INFLUENCE OF COCHLEAR IMPLANTATION ON THE EXPRESSION OF TINNITUS IN PATIENTS WITH DEEP REDUCTION OF HEARING AND DEAFNESS

Abstract

The aim of the study was to study the dynamics of tinnitusin patients after cochlear implantation and to assess the effect of cochlear implantation on the severity of tinnitus. The authors analyzed the results of the questionnaire of 392 patients, assessed the dynamics of changes in the noise level in patients after cochlear implantation during six months in four stages. The assumptions about the mechanisms of tinnitus reduction after cochlear implantation are made. Conclusion. According to the results of the study, a decrease in the level of noise in the ears with the use of a cochlear implant is associated not so much with the effect of habituation, as was generally assumed earlier, but, more likely, with direct electric stimulation of the auditory nerve and acoustic masking. These observations provide the evidence base for a new indication for cochlear implantation as an effective treatment for patients with unilateral deafness and pronounced tinnitus.
