SU1657181A1 - A method for treating hypoacusis in otosclerosis - Google Patents

Abstract

This invention relates to the field of medicine, namely otolaryngology. The aim of the invention is to reduce the recurrence. The goal is achieved by restoring the integrity of the tympanic membrane, fixing the connective tissue autograft to the de-epithelialized edge of the tympanic membrane, then cutting the tendon of the stirrup muscle and the rear leg of the stirrup, removing the portion of the stirrup, then extending the window of the vestibule with the graft and fixing the foramen. shell medial wall of the middle ear. Positive effect provides improved functional results.

Description

The invention relates to medicine, namely to otolaryngology,

The aim of the invention is to reduce the recurrence.

Example. Patient G., 38 years old, was admitted to the clinic on 01/14/88, complaining of hearing loss to both ears, especially to the left ear. The clinic diagnosed - obliterating otosclerosis. 01/18/88, under local anesthesia, an operation was performed on the left ear using an argon laser produced by Kocherent type 920M. conjugated with an operating microscope ONMI-6 of the company Oton. At the beginning of the operation, an autograft is taken from the fascia of the temporal muscle measuring 1x1 cm. After a complete view of the middle ear is achieved using laser radiation, the stapedial muscle tendon is cut first with laser radiation of 1.5 W with a pulse duration of 0.2 s. and then the back leg of the stirrup with a radiation power of 1.7 W, the pulse duration 0.5 s. After the anvil-stapedion joint is separated, the front leg is easily broken with a sharp curved needle. After that, the massive and bumpy base of the staple is thinned by laser radiation with 2.2 W with a pulse duration of 0.5 s at the beginning, and then 0.2 s. After the base of the stirrup is thinned, the laser radiation with a power of 1.7 W with a pulse duration of 0, 2, six holes are made along the perimeter of the future window, and the thinned portion of the base of the stirrup is removed with an ultrathin hook. After that, the window is closed with an autograft from the fascia of the temporal muscle, which is securely fixed by welding it to the mucus

The dura of the medial wall of the middle ear has a laser power of 0.6 W with a pulse duration of 0.2 s. On the long process of the anvil, a bone growth is noted that makes it difficult to install a ceramic prosthesis. An overlap is removed using a 1.6 W argon laser with a pulse duration of 0.1 s, after which the No. 2 prosthesis of alumina ceramics is installed with greater accuracy. In order to secure it, two small pieces of an autograft from the fascia of the temporal muscle are applied to the short processes of the prosthesis, which are welded to the mucous membrane covering the long process of the anvil, each with two laser effects. The distance between them is 0.3 mm (radiation power 0.6 W, pulse duration 0.1 s). The operation went without complication. There were no bullying events both during and after surgery. Audiometry showed a gain of ia 40 dB. The data obtained indicate the feasibility of using the method.
