Accessory nerve lesion after cervicofacial lift: clinical and electrodiagnostic evaluations of two cases.
Two cases of accessory nerve lesion are reported that occurred within 2.5 weeks and 4.5 weeks, respectively, after surgery for cervicofacial lift. The patients were referred for electrodiagnostic examination because of persistent and unexplained unilateral shoulder pain and disability, 6 and 5 months, respectively, after face lift. In both cases clinical examination revealed severe right-shoulder weakness related to trapezius palsy, without trapezius muscle atrophy in the first case and with trapezius atrophy in the second. Electrodiagnosis revealed bilateral accessory nerve lesions in the first case and a unilateral lesion in the second case. Recovery for both cases was progressive but delayed, and both were evaluated 11 and 10 months, respectively, after the first evaluation. Clinical and especially electrodiagnostic findings suggested that the accessory nerve lesion was related to conduction block in the first case and severe axonal loss in the second case.
