[Reconstruction of accessory nerve defects with sternocleidomastoid muscle-great auricular nerve flap].

Objective To describe a new method of accessory nerve defect reconstruction with sternocleidomastoid muscle-great auricular flap. Methods Thirty-four cases receiving traditional radical neck dissection were divided into two groups: single neck dissection group ( n =19) and accessory nerve reconstruction group ( n =15). Surgical procedure of the reconstruction was described in detail. Postoperative shoulder functions were compaired between the two groups. Results Accessory nerve reconstruction group experienced much better shoulder function recovery than that in single neck dissection group. Conclusions Reconstruction of accessory nerve defects with sternocleidomastoid muscle-great auricular nerve flap is simple, effective and complication-free.
