The improved survival of patients sustaining massive head injuries has increased the number of temporal bone fractures being managed by otolaryngologists and neurosurgeons. We performed a prospective analysis of 35 patients with head injury with temporal bone trauma. The major emphasis of this study was to investigate the incidence, management, and outcome of facial nerve injury in such patients and to evaluate the importance of electrodiagnostics in the surgical management of the facial nerve. The results of this study indicate an incidence of fracture type, hearing loss, and facial nerve paralysis similar to that already recorded in the literature. This study underscores the importance of evoked electromyography, or electroneuronography, in assessing facial nerve function. Electroneuronography provided the indications for surgical intervention for facial paralysis. All patients having surgery for facial paralysis as determined by electroneuronographic findings had pathology of the facial nerve.
