[Trans-areola single port endoscopic thoracic sympathectomy for the treatment of palmar hyperhidrosis: a new surgical approach].

OBJECTIVE: To evaluate the cosmetic effects and safety profiles of trans-areola single port endoscopic thoracic sympathectomy. METHODS: A retrospective study was conducted for 45 males and 7 females with palmar hyperhidrosis undergoing trans-areola single port endoscopic thoracic bilateral sympathectomy during April and June 2011. RESULTS: All operations were successfully performed without severe morbidity and mortality. No conversion to open technique was necessary. The mean unilateral operative duration was 6 minutes (range: 5 - 8). The time was calculated from the time of skin incision to that of dressing application over wound. The mean hospitalization duration was 2.2 days (range: 2 - 3). The mean follow-up period was 2.8 months (range: 1 - 7). All patients achieved excellent cosmetic effects. No incision scar was found. CONCLUSION: Trans-areola single port endoscopic thoracic sympathectomy is a safe and effective therapeutic procedure for primary palmar hyperhidrosis. The incision is undetectable with excellent cosmetic effects. The trans-areola route is a new ideal and promising approach for endoscopic thoracic sympathectomy.
