[Comparative analysis of approaches to surgical cochlear implantation in adults and children].

The aim of a surgical stage of cochlear implantation (CI) is to place the implanted part of the device in the temporal space. Criteria of the decision on the side of the intervention and components of it in CI are outlined. To help selection of an optimal variant of surgical intervention in CI at the initial stage, the techniques of the implanted parts insertion are reviewed. Types of skin cuts, approaches to the cochlea, location of cochleostoma, methods of fixing the stimulator are described. The importance of intraoperative registration of the musculus stapedius reflex and action potential of the acoustic nerve in response to cochlear electrostimulation is emphasized. Basing on the experience of treating 38 deaf patients, the author states that for effective performance of the operation it is desirable to conduct reverse U-cut of the skin, make posterior tympanostoma, cochleostoma in the basic cochlear margin, suturing of the cut with intracutaneous suture.
