title: Gunshot injuries of the temporal bone.
abstract: Despite an increasing incidence of gunshot wounds to the temporal bone, there is little in the literature regarding management of survivors of these serious injuries. Twelve patients were treated for such wounds between 1986 and 1994. The most frequent presentations were cranial nerve injury, especially facial paralysis (9 patients), hearing loss (7), vascular injury (4), and vestibular dysfunction (3). Persistent cerebrospinal fluid otorrhea was uncommon (1 patient) in this series. Computed tomography and audiovestibular testing were helpful in evaluating the severity of injury and guiding the surgical approach when necessary. Electroneurography was helpful in evaluating facial nerve function; however, documented disruption of the facial nerve canal in itself was considered an indication for surgical exploration. Other indications for surgical intervention included evidence of dural tear, vascular injury, and severe disruption of the external auditory canal.
