Abstract:ObjectiveTo probe surgical selection indexes of cochlear implantation in patients with internal auditory canal stenosis via observing longterm rehabilitation effect in one patient combined with literature review.MethodsPreoperative audiological data and temporal bone CT images were collected. Sound field test, meaningful auditory integration scale (MAIS) and speech recognition rate test were used to evaluate auditory language skills in half a year, 2 years and 4 years after operation, respectively. Internal auditory canal stenosis, cochlear nerve canal stenosis and cochlear nerve deficiency were used as keywords to browse papers related with rehabilitation effect of cochlear implantation.ResultsHearing thresholds at half a year after operation at 500 Hz,1 KHz, 2 KHz and 4 KHz were 35, 40, 40 and 45 dBHL. Score of MAIS assessment scale at 2 years after operation was 24. Speech recognition rate at 4 years after operation was 80%. The speech comprehension ability was improved significantly 3 years after operation. The rehabilitation effect of our patient was better than those from obtained papers.ConclusionPreoperative analyses of audiological and imaging data are of vital important for cochlear implantation in patients with internal auditory canal stenosis. It is better to choose the side with better cochlear nerve development and hearing aid effect. Meanwhile, it will take longterm commitment to obtain good postoperative rehabilitation.
