Abstract

Introduction: Cochlear implantation for patients with common cavity deformity (CCD) can be difficult, with a higher incidence of intra- and post-operative complications; outcomes with CCD patients are also highly variable. In this study, intra- and post-operative complications were compared between the traditional facial recess approach(TFRA) and the transmatoid lateral semicircular canal approach (TLSCA) with customized electrode. Audiological outcomes and the benefit of using customized electrode arrays for CCD patients are also discussed.

Methods: Retrospective review of 13 cochlear implant (CI) patients with CCD. Six patients were implanted with traditional electrode using TFRA and 7 were with customized electrode using the TLSCA. Intra- and post-operative complications were reviewed. Audiological outcomes were measured three months after surgery. Thirteen CI patients without inner ear malformation served as a control group.

Results: Intra-operative cerebrospinal fluid leakage rates were significant different(p＜0.05) between the two groups, which were observed in 4 out of 6 CCD patients with TFRA, but none out of 7 with TLSCA. There was no post-operative complications. CI outcome of TLSCA group were better than the facial recess group (p < 0.05). While they were significantly poorer (p < 0.05) than those for the control group.

Conclusion: For CCD patients, the transmatoid lateral semicircular canal approach for cochlear implantation is recommended; customized electrode arrays may be additionally advantageous. CCD patients benefit from cochlear implantation, but outcome measures remained poorer than for the control group.
