Cochlear implantation in posttraumatic bilateral temporal bone fracture

Temporal bone (TB) fractures can cause loss of audiovestibular function. Four cases of profound hearing impairment following bilateral TB fracture are presented in this report. All patients received a cochlear implant. All 4 patients became regular users of their implants. None of the patients experienced facial nerve stimulation. Implant-aided audiometry demonstrated a hearing threshold of 28 dB HL. The performance in speech understanding was comparable to standard postlingual adult patients implanted. We believe that cochlear implantation in patients suffering from profound sensorineural hearing losses secondary to TB fractures can be an effective tool for rehabilitation.
