Abstract:
Patients with bilateral temporal bone fractures frequently suffer profound hearing loss. These patients may benefit from cochlear implantation. Displaced fracture lines and ossification of the cochlea might complicate insertion of the electrode array. In the present paper we present a case of a failed cochlear implantation due to ossification of the cochlea, followed by a successful one on the opposite side in a patient who sustained bilateral temporal bone fractures. Preoperative imaging may identify these factors, help guide the appropriate surgical approach and choose which side to implant. We aim to highlight the necessity of imaging and discuss the reliability of computed tomography (CT) scanning in predicting cochlear patency in cases of temporal bone fracture. Possible management options in the case of complex cochlear implantation are also described.
