title: Limiting the anatomic extent of upper thoracic sympathectomy for primary palmar hyperhidrosis.
abstract: Ninety-four consecutive patients undergoing bilateral sympathectomy of the upper part of the thorax for primary palmar hyperhidrosis were reviewed. The supraclavicular operative approach was used and a limited sympathectomy was performed from below T1 to above T3, denervating the palm only. Follow-up evaluation was complete in 86 patients at a median period of 31 months. All patients had complete and permanent relief of palmar hyperhidrosis. However, 19 had compensatory hyperhidrosis and this was the common cause of patient dissatisfaction. Although axillary denervation was not performed, axillary sweating was a problem postoperatively in only two patients. Significant morbidity was minimal; the only permanent disability was in one patient with Horner's syndrome. Upper thoracic sympathectomy is a safe and effective method of treatment for primary palmar hyperhidrosis. The low incidence of compensatory sweating may be explained by the limited extent of the sympathectomy. Axillary sweating is rarely a significant postoperative problem, and extensive sympathectomy to include axillary denervation is unnecessary and should be avoided to minimize compensatory hyperhidrosis.
