Long-term Follow-up of Limited T3 Symathicotomy in Palmar Hyperhidrosis

Background: Conventional thoracoscopic sympathectomy or sympathicotomy is an effective method in treating localized hyperhidrosis; however, this may result in a postoperatively compensatory hyperhidrosis or facial anhidrosis in the treatment of palmar hyperhidrosis. We modified the conventional sympathicotomy by limiting the extent of nerve transection (limited T3 sympathicotomy) since May 1998. However, there are many reports of a good short-term outcome of limited T3 sympathicotomy. Therefore, we reviewed long-term follow-up of limited T3 sympathicotomy based on outcomes analysis using a questionnaire. Methods: Fifty four patients with palmar hyperhidrosis underwent a limited T3 sympathicotomy between May 1998 and March 1999 and had a complete follow-up over two years using a questionnaire (the mean follow-up was 2.6 years). The patients' postoperative satisfaction was determined by their subjective responses to the questionnaires; the degree of compensatory hyperhidrosis, the effects on foot hyperhidrosis, gustatory hyperhidrosis and facial dryness, and recurrence, and patient's satisfaction. Results: Of the total, 87% of patients had a compensatory hyperhidrosis and 3.7% of them were disabled. 31.5% of patients showed improvement in foot hyperhidrosis, while 68.5% of patients demonstrated no change or got worse. 31.5% of patients had gustatory hyperhidrosis and facial dryness and 22.2% of patients showed a mild palmar hyperhidrosis. The postoperative patients' satisfaction was significantly in 96.3% of patients. Conclusions: The limited T3 sympathicotomy is a highly effective treatment of palmar hyperhidrosis and has a low rate of postoperative compensatory hyperhidrosis, gustatory hyperhidrosis, and facial dryness.
