FIELD: otorhinolaryngology.SUBSTANCE: under endotracheal anesthesia, an endoscope equipped with optics and an instrument for removing pathological contents of the maxillary sinus are inserted into the nasal passage. The inferior nasal concha is displaced medially using a raspatory. Then, stepping back from the edge of the piriform opening by 1.5–2.0 cm in the caudal direction, a mucoperiosteal flap of the lateral wall is separated in the lower nasal passage. The mucoperiosteal flap is displaced posteriorly, exposing the bone skeleton in the projection of the inferomedial angle of the maxillary sinus. Next, using a cold plasma coblator, in ablation mode, the mucous surface of the bone skeleton is evaporated for 2–3 seconds, followed by coagulation of small vessels. Then, a bone valve measuring 10–15 mm is formed from the exposed bone skeleton. The bony valve is retracted in the caudal direction, forming an antrostomy. A 70-degree endoscope is inserted through the formed antrostomy and the pathological contents of the sinus are visualized. In this case, if the cyst is visualized with a coblator in ablation mode, the cyst is evaporated along with its contents, and the remaining cyst is captured and removed. If a polyp is visualized, the polyp stalk is first evaporated, and then the remaining part of the polyp is removed. If a foreign body is visualized, it is removed with forceps. In this case, if the foreign body is encapsulated or located in the thickness of the mucosa, a coblator in ablation mode evaporates part of the mucosa until the foreign body is exposed, and then removed. Next, the sinus cavity is washed with saline solution. The antrostomy is closed with a bone flap. The formed mucoperiosteal flap is placed back in its original place.EFFECT: method allows for endoscopic endonasal removal of pathological contents from the maxillary sinuses with a minimal risk of cyst / polyp recurrence and postoperative complications, reduced blood loss during surgery, shortened surgical time, postoperative rehabilitation periods, and temporary disability.3 cl, 3 ex
