An Analysis of the Auditory Rehabilitation Outcomes of Patients with Cochlear Nerve Canal Stenosis after Cochlear Implantation
摘要
Abstract
Objective To evaluate the auditory rehabilitation outcomes of profoundly sensorineural hearing-impaired patients with cochlear nerve canal stenosis after cochlear implantation. Methods The clinical data of 10 cases were analyzed including audiologic data, imaging findings, intraoperative neural responses and postoperative auditory performance. Results The auditory brainstem response, 40 Hz auditory event related potential and distortion product otoacoustic emissions (DPOAE) were absent before cochlear implantation in all the 10 cases. The temporal bone CT showed different degrees of cochlear nerve canal stenosis between the internal auditory canal and cochlear modiolus. The electrically evoked compound action potentials(ECAP)of auditory nerves can be elicited by 3 electrodes in 2 cases, 2 electrodes in 1 case and 1 electrode in 6 cases, but no ECAP waveform was observed in 1 case during surgery. The average vowel recognition rates of 8 patients 3 months,6 months,9 months,1 year and 2 years after cochlear implantation were 60.3%,60.4%,60.3%,60.2%and 60.2%,and the average consonant recognition rates were 19.0%,19,1%,19.1%,19.2% and 19.2%.The average vowel and consonant recognition rate of the 2 patients 3 months after cochlear implantation was 60.1% and 18.2%, respectively. Conclusion The 10 profoundly sensorineural hearing-impaired patients with cochlear nerve canal stenosis have no residual hearing before cochlear implantation and the intraoperative ECAPs can be evoked by only part of the electrodes. After cochlear implantation, the patients have poor auditory rehabilitation outcomes.关键词
