To treat hyperhidrosis, the sympathetic nerves that cause the excessive sweating must be treated. The thoracic sympathetic ganglion chain is located along the vertebra of the spine inside the chest. The T2 segment, located on the side of the upper spinal column, is specifically responsible.
To cure hyperhidrosis, the responsible segment of the nerve is removed. At Cedars-Sinai, the surgeon removes the 2nd and 3rd ganglion from the chain, as well as the 4th one, if necessary, to treat armpit sweating. Removal of these ganglions typically produce no side effects. With Cedars-Sinai's leading-edge surgical techniques, the procedure takes 30 to 45 minutes, and often patients go home the same day without sweaty hands.
About the Surgery
Under general anesthesia, the surgeon makes two small incisions (less than ½ inch in size) in the chest. Through one he places an endoscope (slender tube with a camera on its tip) and through the other, a harmonic scalpel. The procedure uses a harmonic scalpel, which vibrates at high speed, generates no heat and is capable of laser precision. Viewing the inside of the chest on a TV screen, he removes the ganglia. After the incisions are closed, the patient is recovering and on his or her way - with dry hands.
Endoscopic surgery is less painful (minor discomfort), has fewer postoperative complications, can be done on an outpatient basis and requires very little recovery time (normally, a couple of days).
Outcomes, Risks and Side Effects
Almost everyone is a candidate for video-assisted thoracic sympathectomy, except those with a history of severe cardio-respiratory disease, pleural disease or untreated thyroid disease.
Complications are infrequent. Sweaty palms are cured in over 98% of cases. At Cedars-Sinai, our surgeons have performed sympathectomy surgery since 1977 and helped pioneer the endoscopic procedure in 1995.
The surgery can cause side effects, which may vary in occurrence and severity. Compensatory sweating is perhaps the most bothersome possibility. If this occurs, patients may experience excessive sweating on the back, stomach, thighs or lower legs - instead of the hands.
Be sure to discuss all potential risks and side effects with your surgeon before you proceed.
