Abstract

Schwannoma is benign tumor that is originated from the schwann cell. It rarely occurs in the middle ear. Schwannomas of the middle ear may originate from the nerves of the middle ear cavity or by extensions from its neighboring structures. Most schwannomas arising from the middle ear are facial nerve schwannomas. We present a case of a 16-year-old male patient with primary middle ear schwannoma believed to arise from Jacobson's nerves. The tumor was easily dissected from the facial nerve and the chorda tympani nerve. The mass was successfully removed by canal down mastoidectomy, while preserving the hearing and facial nerve functions of the patient.
