[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. Key words: Perspiration syndrome;  Sympathectomy;  Trans-areola
