METHOD FOR SURGICAL TREATMENT OF OBSTRUCTIVE DYSFUNCTION OF THE AUDITORY TUBE Russian patent published in 2022 - IPC A61F11/00 A61N1/18 A61B1/55 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to otorhinolaryngology. Anesthesia is performed. Then an endoscope and an instrument for removing pathological tissue are inserted through the nasal passage to the pharyngeal mouth of the auditory tube. As a tool for removing pathological tissue, the EIC7070-01 electrode is used, having a length of 19 cm, a diameter of 3.7 mm, a bending angle of the working part of 55°, which is used as part of the Arthrocare Coblator II electrosurgical apparatus. The endoscope has a viewing angle from 30 to 45°. Under visual control through the endoscope, the lumen of the auditory tube is revealed by the curved part of the electrode. The area of the lumen of the auditory tube is examined with the endoscope, identifying mucosal pathology: hypertrophy, mucosal hyperplasia or polyp, which causes obstruction of the auditory tube. The working surface of the electrode is combined with the pathological tissue and the electrode is applied to the pathological tissue to remove it. The effect of the electrode includes the supply of normal saline as an electrolyte to the area of the tissue being removed and the effect on this area with energy in the coblation mode, followed by the removal of decay products through the aspiration channel of the working part of the electrode. The power supply mode is constant, until the pathological tissue is completely removed at a coblation power of 230 W, a coblation voltage of 265 V. The working surface of the electrode is moved along the surface of the pathological tissue so that the removal of the pathological tissue is carried out only on half of the surface of the lumen of the auditory tube - on the front or back wall.

EFFECT: method makes it possible to reduce the invasiveness of surgical treatment of obstructive dysfunction of the auditory tube, to carry out treatment of the auditory tube along the entire length, to reduce the number of instruments necessary for surgical intervention.
