ABSTRACT
Cochlear implantation is a high-tech method of rehabilitation of patients with progressive hearing loss, up to deafness. Ossification of the cochlear spiral canal is no longer considered a surgical contraindication for cochlear implantation (CI). However, performing the surgical stage of CI in patients with ossification of the cochlea spiral canal may be accompanied by a number of difficulties. The advanced process of ossification and remodeling can lead to significant difficulty in inserting the electrode into the cochlea, leading to the risk of incomplete insertion. Today, the introduction of an electrode represents the greatest problem during ossification or remodeling of the cochlea since it carries the risk of complications and determines the prospects for subsequent rehabilitation. In addition to incomplete insertion of the electrode, special attention is paid to possible post-implantation stimulation of the facial nerve. Despite the achievement of significant results in the development of surgical techniques for the cochlea ossification management, there are still frequent discrepancies in the assessment of the length of the ossification of the descending segment of the basal coil according to the temporal bones computed tomography (CT) performed at the preoperative stage and the results of intraoperative assessment of the length of the ossification area of the cochlea spiral canal.
