Treatment of Hyperhidrosis, "Sweaty Palms"

Treatment of Hyperhidrosis (Sweaty Palms): Endoscopic Thoracic Sympathectomy

Sweaty palms, known medically as palmer hyperhidrosis, or excessive hand sweating, is the most common presentation of hyperhidrosis. Hyperhidrosis is the medical term for perspiration that is greater than that needed to maintain normal body temperature.

Sweaty palms occur when the body's thermostat stays elevated. To get rid of the resulting excess heat, sweat drips from hands, feet, underarms, or forehead. Sympathetic nerves control sweat; so when these nerves are clipped or divided, the sweating stops.

Treatment at Baptist

At Baptist, physicians perform a minimally invasive procedure called endoscopic thoracic sympathectomy to help treat sweaty palms. The thoracic sympathectomy is performed endoscopically. The surgeon makes two 5 mm incisions at the bottom of the armpit. The lung is permitted to fall away from the inside of the rib cage and a fiberoptic scope with a camera is inserted into the chest cavity. The lung is pushed aside, and the sympathetic chain identified. The camera provides magnification, so structures appear larger and in greater detail than they would to the naked eye. Utilizing a cautery device, the sympathetic nerve branches of the sympathetic chain are cut. The incisions are closed and an identical operation is performed on the other side.

The procedure achieves the same results as an open operation but without the long hospital stays, severe pain, and excessive scarring. The success rate for this type of procedure is typically about 98%.

At Baptist, thoracic surgeon Michael Koury, MD, performs this procedure.
