METHOD FOR RECONSTRUCTING THE LONG PROCESS OF THE INCUS WITH A BIOCOMPATIBLE POLYMER

Abstract

Purpose of the study: to increase the functional effectiveness of tympanoplasty options using a biocompatible polymer. Materials and methods of research: using this method, 35 patients were operated on at the medical center “Medcentre.kg”. Results and discussion. This method ensures the achievement of 10 dB of bone-air gap in approximately 50% of cases, 20 dB in 70%-80% of cases. The method is carried out as follows: Under local anesthesia + neuroleptanalgesia, the mobility of the auditory ossicular chain is checked. If erosion of the long process of the incus is observed with the malleus manubrium and stapes superstructures intact, all mucosa is removed from the bony surfaces and allowed to dry. Next, a biocompatible self-polishing acrylic mixture is applied with point movements to the remaining part of the long process of the incus. The eroded area of the long process of the incus is increased with a biocompatible self-polishing acrylic mixture, allowed to dry, and the mobility of the incus-stapedial joint is checked. The wound behind the ear is sutured in layers. Aseptic dressing. Conclusions. The method of hearing restoration is much cheaper than previously known analogues, such as the use of partial prostheses of the auditory ossicles, does not require a two-stage surgical intervention, and does not contain the risk of displacement of the chain of auditory ossicles, as with the use of prostheses. The biocompatible self-polishing acrylic mixture is easy to work with and hardens within 5 minutes into any desired shape, making it a reasonable alternative for repairing ossicular chain defects without causing any allergic reaction.
