Abstract

Chorda tympani schwannomas are rare benign tumors of the middle ear cleft. This is a case of incidental chorda tympani schwannoma identified intraoperatively.The patient was a 50-year-old male with chronic active otitis media complicated by left-sided facial paralysis. During closed mastoidectomy and tympanoplasty approach, a well-demarcated swelling on the left chorda tympani nerve was identified and sectioned for pathologic evaluation. The histopathologic evaluation established the diagnosis of schwannoma. Although the tumor was unlikely the cause of the disease process in this patient, his facial paralysis and middle ear disease were resolved after surgery.
