Bilateral Cochlear Implantations in Temporal Bone Fracture: A Viable Treatment Option.

ABSTRACT

OBJECTIVES/HYPOTHESIS: Although it is surgically more challenging, patients with bilateral temporal bone fractures (TBFs) are potential candidates for successful bilateral cochlear implantation (CI). This study aimed to investigate the feasibility of bilateral implantation in patients with sustained bilateral TBFs. STUDY DESIGN: Retrospective database study. METHODS: Seven patients with bilateral cochlear implants who were diagnosed with TBFs were included in this study. Preoperative radiological and audiological evaluations were performed. The outcomes of the CI were also investigated. RESULTS: Hearing levels were restored to the mild-moderate range (<40 dB) for nearly all patients and they reported an improved quality of life. CONCLUSIONS: CI in patients with TBF is safe and offers a solution for the restoration of hearing in a population who may experience sudden bilateral deafness. However, preoperative confirmation of intact auditory nerves and patent cochlea is essential to maximize the success of CI in this population. LEVEL OF EVIDENCE 4 Laryngoscope, 1322050-2055, 2022.
