Abstract

Background: To report the presentation, diagnostic process, management and results of cochlear implantation of patients diagnosed with Bjornstad syndrome with profound sensorineural hearing loss (SNHL). A retrospective report of two siblings with Bjornstad syndrome suffering profound SNHL unresponsive to conventional hearing aids treated with bilateral simultaneous cochlear implantation.

Methods: Tertiary-referral center.

Results: Cochlear implant surgeries of two siblings (four ears) with profound SNHL and bilateral inner ear anomaly (incomplete partition type 1) were performed without complications. Postoperative audiometric measurements showed a significiant improvement in pure-tone threshold and a word recognition score. In the literature review, no previous case of Bjornstad syndrome treated with cochlear implantation has been reported.

Conclusions: Cochlear implantation is an effective, safe, and ultimate treatment option for Bjornstad syndrome with profound SNHL not responding to hearing aids.
