Transcanal surgical excision of an intracochlear schwannoma.

An intracochlear schwannoma is a rare cause of sensorineural hearing loss, which is little discussed in the literature. This case report details the presentation of a patient with a sensorineural hearing loss due to an intracochlear schwannoma. The patient was initially managed conservatively; however, as her symptoms and serial imaging indicated progression, the lesion was surgically resected via a transcanal/transotic approach. Diagnosis and management of this unusual schwannoma are reviewed.
