Is ETS a new procedure?
No. Surgical sympathectomy for palmar hyperhidrosis has been performed for well over 30 years. What is new is a minimally invasive approach to this very bothersome problem. Previously surgery required a large incision either in the back of the chest or in the neck to gain exposure to the sympathetic nerve. The new endoscopic approach allows surgeons to gain access to the sympathetic nerve via microscopic, painless incisions. The camera magnifies the nerve so that even the small branches are visible.
