AbstractA severe malformation of the inner ear, often referred to as severe labyrinthine dysplasia or common cavity deformity, consists of an absent or dilated cochlear basal coil, wide communication with the vestibule and a tapered internal acoustic meatus and can be associated with absent hearing. We discuss two children with severe labyringthine dysplasia as shown by computed tomography (CT) scans and, in the first case, an absent VIIIth nerve bilaterally shown by magnetic resonance imaging (MRI). In 1995, both cases were precluded from cochlear implantation, on the basis of the absent VIIIth nerve (first case) and increased risk of CSF leak during operation (second case). However, audiometric results and vocalization patterns of both children suggested the presence of some residual hearing function, while recently reported specific surgical techniques have been found to be safe and effective in the cochlear implantation of the common cavity deformity. The management of such cases should be decided on the grounds of a full audiological assessment in conjunction with the radiological features, in the light of current surgical trends shown to be safe and effective.

Common Causes

At the present stage of medical development, cochlear implantation is the optimal method of auditory and speech rehabilitation for patients with binaural deafness. Congenital cytomegalovirus infection, according to Russian and international scientific literature, is one of the two most common causes of congenital deafness. At the same time, its relevance in cochlear implantation is due not only to its high incidence among patients, but also to the influence on surgical procedure and the final results of hearing and speech rehabilitation. The surgery stage of cochlear implantation in patients with cytomegalovirus infection, due to a number of circumstances, requires individual technical procedure. The most significant thing in this context is the phenomenon of frequent preservation of natural hearing residues at low frequencies, requiring careful and accurate preservation. Moreover, due to the pathogenetic effect of an infectious agent, such patients have a high risk of intraoperative bleeding. Therefore, the most important goal is to prevent the penetration of blood cells into the lumen of the cochlear spiral canal in order to prevent damage to the cochlear sensory structures. However, to date, all the proposed methods of performing surgery in such patients have a number of limitations and do not in all cases meet all the requirements of efficacy and safety. In this regard, on the basis of the St. Petersburg Research Institute of Ear, Throat, Nose and Speech, an original surgical technique was developed for cochlear implantation in patients with cytomegalovirus infection. This technique most significantly meets the requirements of hearing-safe surgical techniques when performing cochlear implantation.
