We assessed medical and surgical causes of unilateral trapezius muscle (TM) palsy and/or wasting. Methods Clinical and electrodiagnostic data were collected in 54 patients with TM impairment over 21 years. Results In total, 35 cases had a medical origin: neuralgic amyotrophy (NA, n = 22), idiopathic unilateral TM palsy ( n = 5), regional neck radiotherapy for different conditions ( n = 2), facioscapulohumeral dystrophy (FSH) ( n = 4), abnormal loop of the jugular vein ( n = 1), or basilar impression ( n = 1). Other etiologies were neck surgery ( n = 16), cervicofacial lift ( n = 2), or trauma ( n = 1). Conclusions There were 5 main diagnostic findings in unilateral TM palsy: (1) dynamic examination of the scapula provides a new clinical sign; (2) NA is the most frequent medical cause; (3) in medical cases, partial preservation of the upper TM can offer good recovery; (4) FSH must be considered, especially in young patients; and (5) minor neck surgery can lead to severe TM palsy.
