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

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.
