Objective To describe clinical experience of the cochlear implantation in Common Cavity Deformity (CCD).

Methods 28 patients with Common Cavity Deformity (CCD), were implanted cochlear in our department from 2012 to October 2019. A retrospective study has been performed about clinical information on these patients.

Results Among all 1367 cases diagnosed with inner ear malformation in our hospital, there were 28 (2.05%) patients with CCD. For patients with CCD, we select the appropriate implant ear, surgical approach, and type of implanted electrode based on preoperative audiology and imaging assessment. Not including the patients lost to follow‐up, subjects we observed had significantly better post‐activation scores on the Categories of Auditory Performance (CAP), Speech Intelligibility Rating (SIR) and Meaningful Auditory Integration Scale/Infant‐Toddler Meaningful Auditory Integration Scale (MAIS/IT-MAIS), with no significant differences between the traditional facial recess approach and transmastoid slotted labyrinthectomy approach (TSLA).

Conclusion Careful consideration of the type of electrode and surgery approach used in patients with a severe deformity is important. Cochlear implantation with customized electrode array through TSLA is safe, effective and can shorten the operation time. For CCD patients combined with CND, it is necessary to pay attention to the selection of implant ear, intraoperative gusher control, and long-term postoperative rehabilitation.
