Spinal accessory nerve palsy: an unusual complication of rhytidectomy

Abstract

Rhytidectomy is a safe and effective procedure for rejuvenation of the aging face. Reported complication rates vary between 2.5% and 28%, and with proper management, longterm sequelae are unusual. Injury to the spinal accessory nerve is a rare but potentially debilitating complication of rhytidectomy. Afflicted patients present with dull, constant pain in the shoulder region which can be serve in nature. In addition, there is weakness of shoulder abduction and cosmetic deformity related to trapezius atrophy. Measures for conservative management include analgesics and physical therapy to strengthen the shoulder girdle. Nerve exploration is indicated for cases with documented denervation that do not respond to conservative treatment. A review of the English literature identified two previous case reports of spinal accessory nerve injury sustained during rhytidectomy. In this report, we present two additional cases and review current concepts regarding diagnosis, management, and prevention of this unusual complication of rhytidectomy.
