High division of the accessory nerve: a rare anatomical variation as a possible pitfall during neck dissection surgery.
A rare clinical variant found during neck dissection surgery is reported in which the spinal accessory nerve divided at a high level in the neck, before entering the sternocleidomastoid muscle. This case documents the need for meticulous technique in identification and dissection of the spinal accessory nerve in order to reduce the risk of postoperative morbidity.
