Abstract:
Objective The purpose of this study is to compare the most comfortable levels and neural re-sponse imaging threshold between children of cochlear implants with large vestibular aqueduct syndrome and normal inner ears. Methods Thirty-eight implanted children participated in this study and were divided into two groups. Group A consisted of 32 patients with normal inner ears and group B 6 patients with radiographically proven large vestibular aqueduct syndrome. All of the patients were the recipients of the cochlear implants by Advanced Bionics. The initial time for the first programming session was approximately one month after surgery. The psychophysical tests included M- level tests. Programming techniques used in the test were suitable for the age of patients. Sound-Wave 1.4 software was used to test tNRI. Results Using the rank sum test, M-level and tNRI of electrode 3,7,11 and 15 did not differ significantly between group A and B(P>0. 05). Conclusion The parameters of mapping are not significantly different between the implanted children with large vestibular aqueduct syndrome and normal inner ear. The management and procedures of mapping used to the subjects with normal inner ear can be applied to the children with large vestibular aqueduct syndrome.
