Non-accidental caustic ear injury: two cases of profound cochleo-vestibular loss and facial nerve injury.
Non-accidental caustic injury is a rare form of child abuse usually secondary to forced ingestion. Caustic injury to the ear most commonly arises from battery lodgement in the external canal. This case series represents the first report of non-accidental caustic injury to previously normal ears resulting in profound sensorineural hearing loss, vertigo with horizontal canal hypofunction and in one patient a severe facial nerve paralysis. Both patients required blind-end sac closure of the injured ear and one required sural nerve interposition combined with transfer of the masseteric branch of the trigeminal nerve to the ipsilateral facial nerve.
