Abstract
OBJECTIVES: To share results and recommendations for management of penetrating cochlear injury. METHODS: A patient underwent repair of a penetrating cochlear injury after a projectile led to a traumatic cochleostomy with a narrow miss of the facial nerve and intracranial carotid artery. RESULTS: Postoperatively, the patient's audiogram demonstrated a pure tone average of 47.5 dB for air conduction and 35 dB for bone conduction, worse in the high frequencies, with a Word Recognition Score of 76%. CONCLUSIONS: Hearing loss from a penetrating cochlear injury can be mitigated with early repair, minimizing inner ear trauma, and steroid use to treat posttraumatic labyrinthitis.
