Abstract:
Objective To study the feasibility of the cochlear implantation and effects in the treatment of large vestibular aqueduct syndrome.Methods A total of 37 patients(74 ears)diagnosed with large vestibular aque-duct syndrome received cochlear implants since 2002 at the Renmin Hospital of Wuhan University.We made a retro-spectively analysis of these 37 patients(37 ears).While 37 patients(37 ears)with normal cochlear structures were considered as the control group.After activation,their speech perception at pre-operation and at 3,6,9,12 months affer the operation were evaluated.Their CAP and SIR scores were collected through questionnaires at each assess-ment interva1 .Results In LVAS group,5 patients(5 ears)had serious gusher,while no gusher was abserved in the control group.The two groups of the electrodes were all inserted in the cochlea.No serious complications occurred after implantation in the two groups.The impedance of the electrodes,the T level,C level and the hearing thresholds were similar with the normal group with cochlear implantations.The results had no significant differences when compared with the normal cochlear group (P>0.05).The speech perception ability,CAP and SIR scores were im-proved along with the increase time of implant use.At the same recovery time,the results had no significant differ-ence in the two groups(P>0.05).At the same group,the results between pre-operation and 3,6,9,12 months post-operation after device activation had significant differences (P<0.05).Conclusion Cochlear implants could be performed safely in patients with large vestibular aqueduct syndrome.The primary outcomes for patients with large vestibular aqueduct syndrome were similar to those with normal cochlear structure following the cochlear im-plantation.
