FESS polysinusotomy (endoscopic polysinusotomy)
A modern method of surgery of the paranasal sinuses. The operation is performed on more than two paranasal sinuses simultaneously.

Chronic inflammatory diseases of the paranasal sinuses, such as sinusitis, can cause many unpleasant symptoms, including nasal congestion, headaches, nasal discharge and decreased sense of smell.
FESS polysinusotomy helps to eliminate inflammation and improve the patency of the nasal passages. The procedure is performed without incisions in the oral cavity, which eliminates the risk of sensitivity changes, and also leaves no cosmetic defects. The polysinusotomy procedure consists in surgically opening and draining the paranasal sinuses to remove pus and mucus, as well as improve ventilation. This helps eliminate chronic inflammation and prevent recurrence of infection.
Before polysinusotomy, it is necessary to consult with an otorhinolaryngologist and an anesthesiologist Perform general blood and urine tests To do a computed tomography (CT) of the sinuses and orbit
The operation is performed under general anesthesia. The surgeon performs the operation using endoscopic equipment through the nasal cavity. By opening the sinuses in the area of natural buds, it gently removes polypous tissue, pus, and fungal bodies. This ensures thorough drainage of the sinuses and correction of anatomical abnormalities that violate the drainage function of the sinuses.
To perform a polysinusotomy, the following methods are used: Endoscope for visualization Surgical instruments (scalpels, forceps, drainage tubes) Anaesthetic equipment Equipment for stopping bleeding (electrocoagulants, solutions)
After the procedure, the patient spends 1-2 days in the hospital for observation. In the early days, it is recommended to avoid physical exertion, do not blow your nose and follow a mild diet. Minor swelling and pain are possible, which disappear within 1-2 weeks. The doctor may prescribe nasal flushing with antiseptic solutions and medications to accelerate healing.
