[The results of bilateral cochlear implantation in the children who survived meningitis].

The objective of the present study was the prospective analysis of the results of bilateral cochlear implantation (CI) in the children presenting with bilateral ossification of the cochlea after they had survived meningitis. A total of 15 patients underwent the surgical intervention. In those exhibiting bilateral ossification of the basal cochlear helix over the 5 mm segment (up to first bend of the cochlear turn) and partial ossification of the second helix (in 6 children), the affected portions were removed with the placement of two choleostomies, the lower one (from the ossified membrane of the cochlear window) and the upper one (toward the second helix).

[The non-damaging method for the insertion of a standard electrode for cochlear ossification].

The objective of the present study was to develop the non-damaging method for the insertion of a standard electrode for cochlear ossification with a view to improving the results of hearing and speech rehabilitation of the patients presenting with grade IV sensorineural impairment of hearing. Twenty preparations of the cadaveric temporal bone were used to investigate topographic and anatomical relationships in the main structures of the middle and internal ears, viz. the second cochlear coil, vestibulum and its windows, processus cochleaformis, spiral lamina, and modiolus.

[PECULIARITIES OF ANESTHESIA DURING COCHLEAR IMPLANTATION IN PEDIATRICS.].

The Aim: analysis of the use of laryngeal mask in anesthesia for cochlear implantation.

Materials And Methods: 10 patients aged from 1 year to 5 years were operated on according to the classical method KI with the use of laryngeal masks. As anesthesia was performed a balanced multimodal anesthesia by Sevoflurane and Fentanyl.

[Optimization of the approach to the spiral (Rosenthal's) canal of the cochlea in the patients presenting with cochlear-vestibular abnormalities].

The objective of the present study was to improve the effectiveness of cochlear implantation (CI) in the patients presenting with cochlear-vestibular abnormalities based on the development and practical application of the algorithm for the insertion of an electrode arrayinto the spiral (Rosenthal's) canal of the cochlea taking into consideration the specific anatomical features of the middle and inner ears. The study included 25 patients with congenital malformations of the inner ear and bilateral grade IV sensorineural loss of hearing or deafness selected for CI. Indications for drilling a cochleostomy were the high localizationof the jugular bulb and the absence of its bone wall (5 patients, 20%).
