Unilateral brachial plexus injury occurring after reduction mammaplasty

A left neuropraxic brachial plexus injury was seen after reduction mammaplasty. The clinical signs of plexopathy were noted in the very early postoperative period. The partial axonal damage was heavy in the upper and posterior branches and moderate in the medial branch of the plexus. The hyperabduction of the upper extremity during the surgery was thought to be the main cause. With a close followup and extensive physiotherapy, in addition to B complex vitamins, a full recovery was achieved at the end of the tenth week.
