About the disease

A sinus cyst is a formation with thin and elastic walls, which is filled with fluid from the inside. The size and location of cysts in the sinus may vary. As a result, the manifestations of cysts may vary from patient to patient.

Inside the mucous membrane, humans have special glands that produce mucus throughout a person’s life. The glands have their own excretory ducts that open onto the surface of the mucous membrane. If, due to an inflammatory process (or for another reason), the gland duct closes, then it stops working, but mucus continues to be produced. The mucus does not find a way out, the walls expand under pressure, which leads to the formation of a spherical container. Most often, cysts form in the area of the maxillary sinuses.

About the disease

Symptoms of a sinus cyst

The following symptoms occur most often:

  • Discomfort in the upper jaw, pressure on the eye.
  • Recurrent or constant headaches.
  • Mucus running down the back of the throat.
  • When diving to depths or sharp ascent, headaches appear or intensify.
  • When the cyst is localized in the sphenoid sinus, complaints characteristic of sphenoiditis are possible.

Complaints depend on the location and size of the cyst and the structure of the maxillary sinus.

Diagnosis and treatment of paranasal sinus cysts

X-ray methods are used for diagnosis. The most optimal is CT (computed tomography) of the nasal cavity and paranasal sinuses, which allows you to determine the size of the cyst and its location with millimeter accuracy.


Treatment of cysts in the paranasal sinuses is possible only with the help of surgical methods. Today, the gold standard of surgery is the use of endoscopic techniques in combination with the FESS technique. In the Otorhinolaryngology Department of the K+31 Clinic, endoscopic instruments are used, which allows the doctor to monitor the entire progress of the operation on the monitor in real time and see the microstructure of the nose. The operation is performed through the nose, which helps avoid incisions on the face. The method has virtually no contraindications, rarely has complications, reduces the time of hospital stay (patients are discharged on the same day) and allows you to return to the normal rhythm of life as quickly as possible.

General information about treatment

Symptoms of a radicular cyst

A radicular cyst can exist asymptomatically for years, gradually increasing in size. The patient may notice swelling in the area of the tooth root. Problems arise when the contents of the cyst, for one reason or another, suppurate and a fistulous tract is formed. In the case of inflammatory phenomena, aching pain appears in the tooth, a feeling that the “tooth has grown”; an opening appears outside, in the gum area, from which the contents are released (the opening of the fistulous tract).

Diagnostics

A reliable diagnostic method is CT scan of the paranasal sinuses.

Treatment of radicular cysts

The treatment is surgical. After consulting a dentist and developing a tactic, the cyst is removed using endoscopic or combined access.

Risk factors and causes of radicular cyst formation

  • Tooth injury
  • Poor quality dental treatment (instrument fragments in root canals, filling material leaving the canal)
  • Hereditary tendency to cyst formation
  • Chronic inflammatory processes of the tissues surrounding the tooth

How is an appointment with an otolaryngologist at K+31?

During the initial appointment, the doctor questions the patient in detail about complaints, clarifies the history of the disease, and lifestyle. Next, a thorough visual examination of the nose, pharynx, ear, and larynx is carried out. Special tests are prescribed to assess the acuity of hearing and smell.

About doctor:

Osipova Irina Andreevna

I had a planned tonsillectomy with E.V. Chekaldina. She's truly a God, not a doctor. As a patient with high anxiety, I received answers to all my questions. She also provided moral and psychological support before and after the procedure. The surgery itself was excellent, with a quick recovery. Visiting Elena Vladimirovna was like visiting a special someone.
