METHOD OF SURGICAL TREATMENT OF PARTIAL OBLITERATION OF MEMBRANOUS-CARTILAGINOUS PART OF AUDITORY TUBE Russian patent published in 2024 - IPC A61F11/20 A61B17/00 A61M25/00 A61K31/573 A61P27/16 

FIELD: medicine; otorhinolaryngology.

SUBSTANCE: vertical incision is made in the posterior part of the tubar ridge. The tubar ridge is lateralized using a nasal elevator-raspator. The recess in the projection of the overgrown pharyngeal mouth of the auditory tube is expanded and the location of the lumen of the auditory tube is determined. Then the pharyngeal mouth of the auditory tube is probed. First it is required to pass through the scar tissue of the pharyngeal mouth of the auditory tube, creating a lumen in it, then to expand it, spreading the said scar tissue to the sides. After that, a silicone microcatheter with a wire-shaped conductor installed inside it is inserted into the expanded pharyngeal mouth of the auditory tube. The conductor is removed when the silicone microcatheter enters the lumen of the auditory tube. The silicone microcatheter is then advanced along the eustachian tube. After making a vertical incision in the posterior aspect of the tubular ridge, a 0-degree endoscope is placed into the external auditory canal. A dexamethasone solution in a volume of 1.0 ml is injected through an installed silicone microcatheter. Diprospan in a volume of 0.5 ml is infiltrated into the tubar roller. Then, for three weeks, a dexamethasone solution in a volume of 1.0 ml is injected into the tympanic cavity through a silicone microcatheter twice a day. Then, on the seventh day and three weeks after the surgical intervention, Diprospan in a volume of 0.5 ml is infiltrated into the tubal cushion, after which three weeks later the silicone microcatheter is removed from the auditory tube.

EFFECT: method allows to restore the functions of the auditory tube due to recanalization of the lumen in the membranous-cartilaginous section, which leads to the resolution of the pathological process in the middle ear.
