Hearing Preservation After Penetrating Cochlear Injury.

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.
