Edema of the mucosa of the left maxillary sinus
The maxillary sinus (or the author's surnamegaimorova) refers to the sinuses, which are attached to the nose, that is, the subordinate. The sinus has the shape of a pyramid, which lies on the side wall of the nasal cavity with its base, and the apex in the zygomatic process of the upper jaw. The remaining walls of the maxillary sinus are arranged so that the front wall faces anteriorly, the second, the ophthalmic, separates the maxillary sinus from the orbit, the third is facing its surface to the transplant and palatine fossa. The size of the sinus varies from 5 to 30 square meters. see Bones, bounding the sinus walls, are lined with mucous tissue from the inside.
The cyst of the left maxillary sinus isbenign elastic neoplasm, the cavity is filled with a liquid that mucus tissue secrete, and can expand as it accumulates, sometimes filling up the entire maxillary sinus. However, the size of the cyst usually does not exceed 7-10 mm.
- Congenital or acquired due to traumacurvature of the nasal septum: In this case, cold air is not sufficiently heated in the nasal passages and causes cooling of the maxillary sinus, which in turn creates favorable conditions for the development of infection with the subsequent formation of a cyst.
- Expansion of the opening of the maxillary sinus in the nasal cavitycavity (congenital or acquired after a disease or injury), which also violates bacterial equilibrium in the sinus and leads to an inflammatory process with excessive secretion of mucus, which is then covered with an elastic tissue and turns into a cyst.
- Complications after acute or chronic diseases of the nasopharynx, paranasal sinuses, mouth cavity, teeth.
- Immunity disorders, weakening of the body.
Sometimes a person can not suspect for yearsexistence of the maxillary cyst. It happens that when climbing mountains, diving, sharp slopes and turns of the head, there are pulling pains in the frontal sinus or the area of the maxillary sinuses, a headache, but this is usually not given much importance. In this case, the cyst is either in the compensation stage or its location does not exert a strong pressure on the pain points.
With an increase in cysts due to thediseases or localization of pain in the painful spots, pains in the jaw area, headache, nasal congestion, left side of the face, swelling of the mucus in the nasopharynx, purulent discharge into the nasopharynx in case of inflammation of the paranasal sinuses.
When the cyst is localized in the region of the trigeminal nerveon the upper wall of the maxillary sinus, there may be a skewed face and pain near the temple and ear. In rare cases, when the inflammatory process spreads, there are temperature, vomiting, symptoms of irritation of the meninges and even epileptic seizures
In addition to the above symptoms, in diagnosiscysts of the left maxillary sinus will burn the radiography of the paranasal sinuses if necessary with the use of a contrast agent. This allows you to determine the exact location of the tumor and its size, as well as outline the tactics of treatment.
Endoscopy is also used, i.e. The introduction of a probe with fiberglass optics through the nasal cavity in the sinus of the nose. With this method, it is possible to obtain a tissue sample of the cyst for research.
A definite result is the puncture of the subordinatesinuses by puncturing through the sinus wall and suctioning the contents of the cyst. Very informative is computed tomography, i.e. layered computer images of the affected area or skull as a whole. Sometimes the method of magnetic resonance is used, but in the case of the cyst it is not so useful
If the presence of a cyst in the leftmaxillary region and special hassles, it does not deliver, treatment is not necessary, Cases of spontaneous resorption of the cyst are described. In cases of pain and discomfort, worsening of the condition or development of complications, surgical intervention is necessary. It is carried by a cut above the lip through the sinus wall.
However, in this case the probability thatthe hole will overgrow with time, very small. The remaining hole in the bone will serve as an entrance gate for infection and lead to chronic inflammation of the head tissue. The method of endoscopic surgical intervention (insertion of the probe through the nose) is more gentle, it can be carried out without general anesthesia and it does not give complications
In the case of a sharp increase in the size of the cyst, itsinflammation and suppuration complications can be very diverse, up to the defeat of the meninges. This depends on the location of the cyst and the degree of activity of the process
