Figure 3-27. Schemes of the structure of the frontal sinuses in the axial (top) and frontal (bottom) planes: 1 - left frontal sinus, 2 - right frontal sinus, 3 - orbital fat bodies, 4 - cockscomb, 5 - perpendicular plate of the ethmoid bone, 6 - cartilage nasal septum, 7 – nasal bone, 8 – nasal wing, 9 – lacrimal gland, 10 – muscle that lifts the upper eyelid.

Table of contents:

In 53% of patients, pronounced asymmetry of the frontal sinuses is observed (Fig. 3-31, 3-33, 3-34). And only every tenth out of a hundred are relatively symmetrical. It should be noted that the shape, size, and location of the frontal sinuses are the most variable of all SNPs. To a greater extent, this asymmetry concerns the position of the sinus septum, additional septa and the lower wall. In these cases, the information content of CT turns out to be significantly higher than radiography and tomography, since with its help it is possible to see all the walls of the sinuses, as well as differentiate sinus hypoplasia from its shading during the inflammatory and tumor process.

The cribriform plate is better visible in the frontal projection. Centrally located on it are: on top - the cock's comb, on the bottom - the vomer (Fig. 3-30). In the same plane, the nasal concha and ethmoidal openings are clearly visualized. In frontal sections, it is also quite easy to recognize the posterior ethmoidal cells and the upper sections of the maxillary sinuses, which, by the way, is difficult to do in axial sections.

Rice. 3-28. Frontal sinuses (CT scan was performed in the axial plane): 1 – left frontal sinus, 2 – septum of the frontal sinuses, 3 – right frontal sinus (with pneumatization spreading to the upper wall of the orbit from the frontal sinus – type I pneumatization), 4 – additional septum, 5 – additional pocket of the frontal sinus.

Asymmetry in the development of the frontal sinuses and ethmoid bone (hypoplasia on the left); I (first) type of pneumatization of the orbital roof on the right. The right image shows a three-dimensional reconstruction of this area of ​​the skull using a series of frontal tomograms.

On a computed tomogram of a patient with aplasia of the left frontal sinus (lower right picture), two adjacent round low-density areas are identified in the posterior sections of the section - areas of pneumatization of the dorsum sella (normal variant).

Rice. 3-34. Type I pneumatization of the orbital roof on the right and mixed type on the left.

The ethmoidal cells are quite clearly visible on axial sections (Fig. 3-35, 3-36). This plane can be recommended as the main one when studying the ethmoid bone, although these structures can also be studied in the frontal plane.

Since the medial wall of the orbit, which this bone forms, is located obliquely, its visualization on radiographs is difficult, but on CT sections it is visible along its entire length. The medial wall of the orbit is so thin in places that its contours on a computed tomogram, especially in the central part, appear intermittent in approximately 70% of patients (Fig. 3-37). The symmetry of these structures is a sign of normal development of the ethmoid bone; asymmetry, displacement of bone plates by soft tissue masses indicate the presence of a pathological process (Fig. 3-33).

The ability to see all parts of the ethmoid bone with polyposition radiography is significantly hampered by the presence of a large number of bone structures layered on top of each other in the image; To a certain extent, this obstacle is eliminated with traditional linear tomography. However, its structure, degree of aeration, presence or absence of soft tissue formations and individual anatomical features could be recognized in detail only on computer tomograms (Fig. 3-38...41). The latter circumstance makes it possible to highly evaluate the influence of computed tomography on the planning of surgical intervention, for example, in terms of determining the surgical approach and/or the extent of the operation.

Rice. 3-36. Computed tomogram of the ethmoidal labyrinth in an axial projection: 1 – frontal sinuses, 2 – anterior cells, 3 – middle cells, 4 – posterior cells, 5 – sphenoid sinus (right and left halves). As a rule, on an axial section, all sinuses can be seen simultaneously, which, in some cases, significantly reduces diagnostic time.

hypoplasia of the frontal sinus what is it

Hypoplasia of the frontal sinuses - what is it?

In the section Diseases, Medicines, to the question Hypoplasia of the frontal sinus, what is it? asked by the author Skipy _ the best answer is this is underdevelopment of the nasal sinuses

Hypoplasia is a congenital underdevelopment of an organ, manifested by a deficiency in its mass or a decrease in size. Hypoplasia of the frontal sinus is not a rare phenomenon that does not pose any negative consequences for humans.

MRI for diseases of the paranasal sinuses

MRI for diseases of the paranasal sinuses

There are many clinical conditions whose nature and distribution can be clarified by MRI.

To begin with, it is worth saying a few words about the development options, of which the most common are hypoplasia and aplasia of the sinuses.

Hypoplasia of the frontal sinus

Particularly noteworthy is such a development option as excessive pneumatization of the sphenoid sinus and posterior ethmoid cells in the form of developed upper lateral recesses, in the presence of which the internal carotid arteries and optic nerve canals can protrude into their lumen. As a result, during inflammatory processes in the mucous membranes of these sections (including subacute and chronic), a clinical picture of progressive atrophy of the optic nerves may develop. In addition, when performing surgical interventions in this anatomical area, the risk of damage to the carotid arteries and optic nerves increases many times.

Developed superolateral recesses, against which the optic nerves are identified

Inflammatory changes in the paranasal sinuses are the most common diseases of the upper respiratory tract. From 5 to 15% of the world's population suffers from various types of sinusitis. In addition, there is a trend towards an increase in chronic forms.

Facial pain with sinusitis is localized in the projection of the affected sinus. With frontal sinusitis and sinusitis, in addition to pain, there is pain on palpation. Ethmoiditis and sphenoiditis are characterized by constant pain in the eye and nose and nasal congestion. Diagnosis of chronic sinusitis is especially difficult. With mucoceles and tumors, swelling and displacement of the eyeball are observed: upward - with damage to the maxillary sinus, outward - with damage to the ethmoidal labyrinth, and downward - with damage to the frontal sinus.

Let's look at examples of pathology of the paranasal sinuses detected during an MRI examination.

Swelling of the mucous membrane of the right maxillary sinus with fluid level

MR picture of polysinusitis with a total disturbance of pneumatization of the cells of the ethmoid bone, moderate, sometimes uneven, local disturbance of pneumatization of the right half of the main sinus and the upper parts of the left maxillary sinus, without an exudative component.

Chronic rhinosinusitis

characterized by parietal thickenings caused by hyperplasia of the mucosa and partial fibrous changes in it. The thickness of the mucous membrane ranges from 4-5 mm.

Sinonasal polyposis, hypertrophic sinonasal rhinosinusitis. Non-tumor inflammatory swelling of the mucous membrane.

Mycotic sinusitis

Recently, there has been an increase in the number of fungal sinusitis.

Chronic forms occur under the guise of polypous recurrent sinusitis, the MRI picture is nonspecific, and laboratory diagnosis is difficult.

There may be a change in the bony walls of the sinuses due to hyperostosis or destruction of the sinus wall as a result of prolonged pressure from the fungal body.

Mycetoma

non-invasive fungal sinusitis of the left maxillary sinus

The hypointense MR signal of a mycetoma may be mistaken for air in the paranasal sinus; Non-invasive fungal sinusitis does not look the same in different sequences.

Maxillary sinus cysts

If they are large, they cause headaches due to the pressure of the cyst shell on the walls of the sinus.

Often combined with allergic rhinitis, hypertrophy of the nasal turbinates and deviated nasal septum

Large cysts located in the lower parts of the maxillary sinus may be asymptomatic, while a small cyst located on the upper wall, in the area of ​​the 2nd branch of the trigeminal nerve, can cause headaches.

Mucocele of the ethmoid labyrinth and frontal sinus on the right

This is a large formation of the paranasal sinus, lined with epithelium and filled with mucus, which is formed as a result of obstruction of the main sinus canal.

The most typical symptom: expansion of the paranasal sinus with smooth, clear contours with thinning and remodeling of the adjacent bone plate.

Benign tumors of the paranasal sinuses

Angiofibroma

Benign vascular space-occupying lesion with slowly aggressive growth; localized in the nasal cavity; grows around the posterior wall of the nasal cavity, along the edges of the pterygopalatine foramen; in the early stages penetrates into the pterygopalatine fossa (arrows), grows into the medial pterygoid plate

Transitional cell papilloma

a rare, but benign tumor characteristic of the nasal cavity and its sinuses. More common in men. As a rule, it occurs on the side wall of the nasal cavity, as well as in the paranasal sinuses. From the nasal cavity, a tumor can grow into the paranasal sinus and vice versa. Patients usually complain of nasal congestion, discharge, nosebleeds, and pain in the facial nerve area. Sometimes bone tissue is destroyed in the area of ​​tumor growth.

Transitional cell papilloma with bone wall remodeling

A formation in the center of the middle nasal meatus, accumulating a contrast agent, spreads into the maxillary sinus and/or cells of the ethmoid bone labyrinth

Malignant tumors of the paranasal sinuses

The most common (58-90%) is squamous cell carcinoma.

1. are asymptomatic for a long time, under the guise of inflammatory changes, especially in the absence of destruction of the walls

2. quickly spread to neighboring structures and, by the time of recognition, infiltrate several areas

3. it is difficult or impossible to determine the original site of tumor origin

4. extremely rarely metastasize to distant organs and tissues

5. it is not possible to clearly define the boundaries of the lesion

6. MR semiotics: tissue formation, spread to surrounding tissues, bone destruction

If bone structures are damaged - the hard palate and the alveolar process of the upper jaw, it is necessary to undergo an additional radiological examination - X-ray CT, which clarifies the presence or absence of bone destruction.

Detection of tumor tissue against the background of soft tissue structures - the pterygopalatine and infratemporal fossa, masticatory muscles, soft tissues of the cheek, as well as the spread of the tumor to the frontal and sphenoid sinuses, the ethmoidal labyrinth intracranially requires MRI (with contrast enhancement). In addition, MR imaging is indispensable in the differential diagnosis of postoperative or post-radiation changes with relapse or continued growth.

Thus, in order to exclude a pathological process and begin treatment on time, it is necessary to undergo a complete radiation examination.

    What is hypoplasia of the frontal sinus

    The frontal paranasal sinuses are second in size after the maxillary sinuses. In another way they are also called frontal. They are concentrated in the thickness of the frontal bone in the area just above the bridge of the nose. We are talking about a paired anatomical formation, which is divided into two parts by a special partition.

    When and how are the frontal sinuses formed?

    Few people know, but not all people have frontal sinuses. According to statistics, about five percent of the entire population of the planet does not have them at all. In this case, a diagnosis of frontal sinus aplasia is made. But you should not be afraid of this term, since the absence of one or two frontal sinuses does not pose any danger and does not lead to negative consequences.

    The frontal sinuses (sines) are located in the frontal bone, just behind its brow ridges. The lower walls of the frontal sinuses act as the upper walls of the orbits. As for the posterior walls, they serve to separate the sinuses from the frontal lobes of the brain.

    The newborn does not have frontal sinuses. They develop gradually and are formed by the age of 8 years (at this time their volume does not exceed 7 milliliters). The sinuses reach their maximum size only at the age of 25, when final puberty occurs. As a rule, such organs are not symmetrical, because the septum that divides them is slightly tilted to one side (relative to the middle). Some people, in addition to the main bony septum, may have additional ones.

    The size of the frontal sinuses can vary widely. They perform such important functions as forming the voice timbre, organizing normal nasal breathing, and forming the bones of the facial area.

    Let's understand the terms

    To indicate the complete absence of sinuses or a delay in their normal development, doctors use different (but essentially identical) terms and designations:

    In some clinical cases, regressive development of the sinuses is possible when an inflammatory process occurs and affects the already developed frontal sinuses. Quite often I use agenesis and aplasia as synonyms, denoting the same phenomenon.

    If we take into account the characteristic features of the formation of the frontal sinuses, then it makes sense to use the terms aplasia and agenesis. The first word denotes the complete absence of the process of formation and development (hypoplasia of the frontal sinuses). The second is that there is a delay in the process of organ formation that has begun.

    As a rule, as aplasia develops, doctors diagnose bone compaction in the area of ​​the brow ridges. This pathology will manifest itself especially clearly in the so-called marble disease.

    Signs of paranasal sinus abnormalities

    Birth defects and anomalies can be directly related to hereditary pathology, when the normal process of formation of other cranial parts is disrupted. For example, abnormal development of the maxillary sinuses (maxillary sinuses) is detected in 13 percent of children diagnosed with sinusitis. Most often, anomalies of the paranasal sinuses manifest themselves as follows:

    1. A person’s sinuses may be partially narrowed or completely absent as a result of excess pressure on them from the facial or nasal walls. In this case, underdevelopment will vary widely, starting with a slight depression of the canine fossa, and ending with complete fusion of the nasal wall and the facial wall. In the latter case, the sinus simply disappears in the lower section.
    2. Doctors often diagnose unilateral anomalies. In this case, facial asymmetry is clearly visible. When attempting to puncture (puncture) an underdeveloped sinus, the doctor’s needle passes into the soft tissue of the cheek.
    3. Anomalies and defects of the frontal sinuses will differ from each other in both their size and volume. In some clinical cases, doctors diagnose agenesis of the frontal sinuses with a volume of up to 500 milliliters. There are four main types of delay in the development of sinuses. We are talking about a violation of pneumatization or its complete absence, unilateral or bilateral aplasia of the frontal sinus, trabecular agenesis and secondary sclerosis (regressive type anomaly).
    4. It is worth noting that aplasia is most often diagnosed in men. In addition, with unilateral disorders, the most reliable diagnosis is poor development of the opposite sinus.

    The influence of aplasia on the occurrence of sinusitis

    At the moment, clinical studies do not confirm the effect of agenesis or aplasia of the frontal sinuses on the nature and frequency of nasal pathologies.

    Underdevelopment or absence of the sinus does not in any way affect the form and frequency of inflammatory processes. In addition, this does not in any way affect the occurrence of pain.

    With aplasia, patients are most often diagnosed with the following types of sinusitis:

    According to doctors, an underdeveloped sinus is not involved in the inflammatory process during sinusitis. This is especially true when there is a unilateral delay in its development.

Frontal sinus aplasia

Aplasia is the absence of an organ or its presence in a rudimentary, underdeveloped state. So it cannot function fully, which can sometimes become a predisposing factor for certain diseases.

Aplasia of the frontal sinuses occurs no more often than in 3-5% of patients in the ENT department. Some doctors replace this term with agenesis, atresia or hypoplasia, since these definitions are synonymous.

The structure of the frontal sinuses

The frontal sinuses are a continuation of the paranasal sinuses, that is, the paranasal sinuses. They are located immediately under the brow ridges, being the upper walls of the eye sockets. The average size ranges from 2-3 cm, and the volume can reach 7 ml. The production of mucus in the organ is controlled by the supraorbital nerve.

In newborns, the frontal sinuses are completely absent. The main formation of the organ ends by the age of 8 years. The maximum size of the cavity is reached only when a person is 25 years old.

Often these sinuses are asymmetrical in size, and the septum between them can be deviated to the right or left. Hypoplasia of the frontal sinuses is the complete absence of one or two sub-brow cavities.

Causes of aplasia

Aplasia of the frontal sinus is a congenital defect directly related to a malfunction in the genetic code of the fetus or exposure to teratogenic factors on a pregnant woman.

These include the following impacts:

That is, any incorrect actions of the mother during pregnancy can affect the full development of the unborn child. For example, taking any strong medications, abdominal injuries, smoking, drinking alcohol, poor lifestyle or dangerous work.

Sometimes aplasia is inherent in the patient's genetic code. Therefore, if such an anomaly was found among relatives of even the most distant generations, we can confidently speak about a hereditary predisposition.

Signs of anomaly

Hypoplasia of the frontal sinus is an anomaly that is rarely diagnosed in completely healthy patients. Most often it is detected when a person goes to the doctor with any complaints. There are several signs that distinguish aplasia.

These include the following features:

  1. Sometimes narrowing of the paranasal sinuses develops due to pressure on them from the facial or nasal wall. In some patients this anomaly will involve depression of the canine fossa, in others it will involve fusion of the nasal and facial walls.
  2. If a person is diagnosed with unilateral underdevelopment of the frontal sinuses, asymmetry on the face is observed with the naked eye.
  3. Sometimes the presence of an underdeveloped sinus is revealed during puncture. When performing a puncture, the specialist notes that the needle passes through the soft tissue of the cheek.
  4. If the anomaly is one-sided, in the absence of one sinus, the second will also be underdeveloped.
  5. Most often, aplasia is diagnosed in males.
  6. Sometimes the inflammatory process in the body provokes regression in the development of existing sinuses. In this case, the cavities can significantly decrease in size.

However, the presence of any signs or predisposing factors in the patient’s life does not guarantee the occurrence of pathology in the structure of the sinuses. You can find out for sure about their presence or absence only after a high-quality diagnosis.

How is it diagnosed?

There are several types of diagnostics that help determine the presence of any pathological processes in the frontal sinuses. To conduct a full examination using equipment, you need to consult an otolaryngologist.

For diagnosis the following is carried out:

  1. X-ray examination. X-ray helps determine the enlargement of the sinus, the structure of the septum in this organ, and the severity of its contours.
  2. Computed tomography (CT). It is the same scan using an X-ray machine, but with CT, the organ is studied using layer-by-layer sections. This helps to more accurately determine the location of the cavity, its structure and the thickness of the bone wall between the sinuses. Computed tomography also helps to identify inflammatory processes, degenerative changes in the facial bones and other anomalies.
  3. Ultrasound examination (ultrasound). Non-invasive and safe diagnostic method. It is often used in young children due to the absence of any pain, as well as harmful effects. It is often prescribed when the doctor has doubts about the data obtained after an x-ray.
  4. Magnetic resonance imaging (MRI). It is one of the most highly informative diagnostic methods. The resulting image has high contrast, helping to identify the presence of a tumor or inflammatory process in the area. A significant advantage of MRI is the absence of x-ray radiation with a high quality diagnostic examination.

As a rule, hypoplasia is diagnosed using these techniques when a patient presents with any complaints. That is, the anomaly is rarely detected on its own. Most often, a person learns about it when any disease appears in this area.

Aplasia and diseases

Today, experts confidently say that there is no connection between the occurrence of sinusitis and the presence of anomalies in the development of the frontal sinuses in the patient.

Underdevelopment or absence of cavities under the brow ridges does not affect the frequency and extent of the inflammatory process, as well as the presence of more severe pain during the illness.

For example, only 10% of patients with chronic sinusitis are diagnosed with frontal sinus hypoplasia. That is, 90% of people suffer from this pathology, without having any congenital anomalies in the structure of the facial bones.

The pathology cannot be eliminated surgically, so its presence should be perceived as a peculiar feature of the body. There is no connection between hypoplasia of the frontal sinuses and the detection of an inflammatory process in this area.

Treatment of such patients is no different from identical clinical cases without such pathology.

Underdeveloped frontal sinuses

These are the sinuses of the nose, which in medicine are called paranasal or paranasal. Necrosis of tissue in the paranasal sinuses. The paranasal sinuses are voids located in the facial area of ​​the skull. At birth, children's paranasal sinuses are in an underdeveloped state, and they have no frontal cavities at all. The ethmoidal labyrinth is located between the main and frontal sinuses.

The accessory nasal cavities are formed inside the womb and complete their development during puberty. They have an epithelium that produces mucus. So, the largest sinus is the maxillary sinus. The frontal sinus is divided into 2 parts, and its sections are pneumatized in different ways.

If the doctor suspects the presence of inflammation in the sinuses, he may send you for an X-ray examination. Reduced pneumatization appears with inflammation of the maxillary sinus, when its lower septum is clearly thin. Most often, the maxillary and frontal cavities become inflamed due to their anatomical location. An x-ray of the paranasal cavities immediately shows a decrease in air filling of the affected sinus. Late diagnosis and delayed treatment can lead to serious consequences due to the proximity of the nasal cavities to other vital organs.

Good afternoon The ENT specialist told me to take a picture of the sinuses, I did it and in the conclusion they wrote: The nasal septum is deviated. The frontal sinuses are underdeveloped. I saw swelling in my nose and sent it for a picture! However, few people understand the importance of the paranasal sinuses and the role they play.

If there is a cyst in the maxillary sinus

Almost every adult has four pairs of paranasal sinuses: maxillary, main, frontal and ethmoid labyrinth. They are located in the bones of the facial skeleton and are air cavities. In this regard, the inflammatory process from the nasal passages in the vast majority of cases passes into the paranasal sinuses. They are located in the thickness of the upper jaw, hence their name.

This is why inflammation of this sinus sometimes causes vision complications. It is thanks to this opening that the paranasal sinuses are airy: everyone needs to know that this is an important element of the paranasal cavities.

The main, or sphenoid, sinuses are located in the body of the bone of the same name. Unlike other adnexal cavities, they are considered unpaired. But at the same time there is a special partition that divides the sinus into 2 parts with separate excretory channels.
The frontal sinuses are located behind the brow ridges in the body of the bone of the same name. These cavities are formed by the front, rear, bottom and inner walls. The maxillary sinuses are located on either side of the nasal pyramid under the facial cheekbones.

It is thanks to the paranasal sinuses that each person has a unique sounding voice. Since the process of producing mucus occurs without stopping, the anastomosis in the sinuses must always be open, through which this mucus can freely exit into the nasal cavity. If inflammation begins in the maxillary sinus, the first symptom that the patient feels is headaches. The danger of sinusitis is a pathological increase in intracranial pressure.

Paranasal sinuses: their structure and role

Normally, an x-ray of the maxillary paranasal sinuses will show clear contours of the bones, pneumatization will be compared with the orbits, and the ethmoidal labyrinths can be easily traced. If the patient has sinusitis, then the pneumatization of the sinuses will be reduced, and the image in the area of ​​the cavities will be darkened.

This method of treating sinusitis is recommended only in cases where the patient’s anastomosis structure is not disturbed and all liquid can move normally through the nasal cavity. Sometimes patients undergo sinus lavage along with laser therapy.

Washing is carried out under slight pressure, which promotes the outflow of purulent exudate from the sinuses. To treat sinusitis you will need to undergo at least 5 rinsing sessions. Very often, for an ENT specialist, a cyst becomes an unexpected finding after diagnosing the sinuses with radiography. There are no special signs of its development, so it is impossible to detect neoplasms in the accessory cavities without x-rays. A sinus cyst requires removal because it does not respond to conservative or alternative treatments.

Accordingly, the hole heals by scarring, which leads to a violation of the integrity of the maxillary sinus. This is the most physiological method of removing a cyst from the maxillary sinus. The instruments are inserted through the sinus anastomosis and nasal canals, so no external incisions are required. If, in addition to the cyst, the patient has a deviated nasal septum, then during removal of the tumor, the septum is also corrected.

The maxillary sinuses are affected: how is treatment carried out?

The term "sinusitis" is a common name for diseases of the paranasal sinuses. These ailments include sinusitis, frontal sinusitis, ethmoiditis and sphenoiditis. Frontal sinusitis refers to the process of inflammation in the frontal sinuses. Ethmoiditis affects the ethmoid bone. And with sphenoiditis, pathology develops in the sphenoid sinus. Most often in medical institutions, patients are diagnosed with sinusitis and frontal sinusitis, and sometimes these ailments are determined together.

Maxillary (maxillary) sinuses

Sinusitis is an inflammation of the maxillary (maxillary) sinus, and frontal sinusitis is the frontal sinus (from the word frontalis, which means “frontal”). Sinusitis and frontal sinusitis in the acute phase last no more than 2 weeks. Viruses penetrate inside, resulting in inflammation. As soon as the microbe enters the nose, the body responds with an immune response.

A lot of people have underdeveloped frontal sinuses, and some have them completely absent. X-ray determines the location of the sinus. The sinus is washed with an antiseptic, and a drug is injected into it. This will help avoid the development of many diseases, including those that take a chronic course. The beginning of the development of the paranasal sinuses dates back to the 8-10th week of embryonic life, and the rudiments of the maxillary bone and ethmoidal labyrinth appear the earliest (at the 8th week).

The maxillary, or maxillary, sinuses are the largest of all the accessory cavities. Sinusitis is the development of an inflammatory process in the maxillary sinuses. After all, the inflammatory process quite quickly moves into the paranasal sinuses. The size of the sinus cyst, as well as the location, varies.

What are developmental anomalies of the paranasal sinuses?

Anomalies of the paranasal sinuses may be one of the symptoms of a combined genetic syndrome with deviations in the development of other parts of the skull. Anomalies of the maxillary sinuses are detected in 13% of children with various forms of sinusitis.

Symptoms of Abnormalities of the Paranasal Sinuses

With anomalies in the development of the maxillary sinuses, the following symptoms are most often observed.

Complete absence or partial narrowing of the sinus due to depression of the nasal or facial wall into it. The degree of underdevelopment can vary, from a slight depression of the canine fossa (fossa canina) to the fusion of the facial and nasal walls with the disappearance of the sinus in the lower part.

With a unilateral sharp anomaly of the maxillary sinus, pronounced facial asymmetry is formed. When attempting to puncture such a sinus, the needle passes into the soft tissue of the cheek.

In some cases, the sinus is multi-chambered, preferably divided by a complete bone septum into two cavities, of which the upper one communicates through the natural opening with the middle nasal passage, and the lower one communicates through the lower ethmoidal fissure (fissura ethmoidalis inferior) with the posterior ethmoidal cells.

Congenital anomalies of the frontal sinuses vary in size and volume. Sinus agenesis and underdeveloped sinuses up to 0.5 ml. There are 3 types of agenesis of the frontal sinus: complete absence of pneumatization; aplasia of the frontal sinus on one or both sides, trabecular agenesis, secondary sinus sclerosis.

Sometimes there are giant sinuses with a volume of more than 500 ml.

According to various authors, in 2.5-20% of cases the frontal sinuses are absent.

Diagnosis of developmental anomalies of the paranasal sinuses

Hypogenesis of the outlet openings of the paranasal sinuses can only be detected with microrhinoscopy or fibrorhinoscopy. Defects in the development of the paranasal sinuses must be taken into account when interpreting diagnostic and clinical data.

Forecast. In all cases, when congenital anomalies of the nose and paranasal sinuses are detected in children, it is necessary to carefully analyze the hereditary and family history to determine the most likely teratogenic factors.

What does it mean that the frontal sinus is not developed?

The frontal sinuses are an integral part of the paranasal cavities. This area is responsible for several functions, but the main task is to protect the body and normalize the pressure of the respiratory tract.

It is important to know that the frontal sinuses are located in close proximity to the brain, so inflammation in this area is especially dangerous. It is known that almost fifteen percent of people suffer from diseases in this area.

About the frontal part and pneumatization

Unfortunately, it is impossible to prevent this side from the penetration of microbes, cyanobacteria, shigella, enterobacteria, enterococci and other numerous harmful elements, therefore, if an infection enters the body, in which the temperature rises and inflammation of the respiratory tract is characterized, as well as pain in the ears or head, the frontal area should be checked.

Sometimes the frontal sinuses are undeveloped or completely absent. With this anatomical structure, a person often complains of headaches.

The paranasal sinuses, located in the forehead area, are located just above the nose and are voids in their structure, and are connected to the nasal sinuses area using a certain frontonasal fold. Penetration of harmful elements into the head area occurs precisely through this element. When microbes enter the nasal fold, the patient experiences severe discomfort and other unpleasant symptoms.

Note that the depression in the forehead is a paired organ and therefore the disease always occurs on both sides.

This side resembles a triangle measuring five centimeters, but the cubic size can vary depending on the individual structure of the patient’s body. Inside the sinus there is a mucous part that envelops all four parts of the frontal sinus:

All four parts help protect the brain from the penetration of viruses and bacteria, as well as changes in atmospheric pressure, trauma to the skull, and the body’s adaptation to weather changes. In addition, this part is responsible for the following functions:

  • transmission of sound impulses;
  • increasing air temperature and adapting it for subsequent processing;
  • moisturizing the mucous area;
  • regulation of pressure in the nasal sinus;
  • As the skull develops, this side reduces its mass.

The frontal sinuses are not developed - what does this mean?

It is known that at birth in newborns the frontal recess is not fully developed or is completely absent. The accessory cavities begin their formation while in the mother’s belly, but complete their formation only closer to 18 years of age or during puberty.

If, upon examination by a doctor, it was diagnosed that the child’s frontal sinus is not developed, there is no need to be afraid. The largest region, called the maxillary region, is formed only at adulthood, and before this time each part of the frontal sinus can be pneumatized.

If there is a suspicion of undeveloped frontal sinuses in an adult, the doctor may send for additional examinations. This is necessary if there is a risk of disease formation due to the penetration of viruses or microbes, as well as if there is a risk of a tumor or cyst.

It is known that with reduced pneumatization, disease of the maxillary region occurs. This most often occurs when the area of ​​the lower septum is too elastic. In addition, if the right frontal sinus or both parts at once are undeveloped, the patient often complains of pain in the head and temporal region, as well as a feeling of constant pressure on the bridge of the nose.

A common cause of frontal disease is the anatomical structure. When examined on an x-ray at this time, it is clear that the paranasal cavities are filled with air. In this case, the patient is given treatment in which the general condition is normalized and excess air flows are removed. With poor quality or incorrect therapy, disease in this area leads to consequences that are dangerous for overall health.

It is important to note that children do not have frontal sinuses at all. Before the age of eighteen, they are just beginning to develop and form in the upper part of the eyes. Towards the completion of formation, this side grows into the mucous region of the nose and becomes covered with mucous membrane.

At the same time, the dissolution of the spongy bone occurs, which is located between the inner bone and the outer part of the skull.

Conclusion

With sharp pain in the head or nasal area, doctors often diagnose voids in the frontal sinus. In this case, patients complain of a feeling of pressure in the bridge of the nose, pain in the forehead, excessive production of tears, as well as anemia.

When palpating the wall of the eyes, sharp shooting pains often form. In this case, an individual course of treatment is prescribed.
