Abstract
IntroductionMiddle-ear adenoma is a rare benign endocrine tumor with slow progression, and can, in very rare cases, lead to recurrent peripheral facial palsy. Case reportA young man experienced three episodes of right peripheral facial palsy of incremental intensity, suggestive of barotrauma. CT and MRI found a tissue mass in the tympanic cavity, and biopsy diagnosed middle-ear adenoma. Electroneuromyography found 50% impairment of facial function. Closed right tympanoplasty with complete tumor resection enabled complete recovery of facial function within 1 month. DiscussionMiddle-ear adenoma is diagnosed on histology, as imaging on MRI can be non-specific, mimicking chronic otitis. Facial involvement is rare and is due to edematous compression of the vasa nervorum. Treatment is surgical, and follow-up should be prolonged. Palsy assessment on electroneuromyography indicates the urgency of treatment.
