Since nonsurgical treatments of hyperhidrosis have only limited success, surgery is the only true cure for this condition. The surgical treatment for hyperhidrosis is a procedure called Endoscopic Thoracic Sympathectomy, sometimes called ETS. The procedure has about a 98% success rate in curing cases of overly sweaty palms, although the same procedure will treat hyperhidrosis in all areas of the body.
Simply put, the sympathectomy procedure severs, or interrupts, the nerves connected to the affected sweat glands. The procedure is performed through small incisions in the underarm area. The surgeon then locates and operates on the sympathetic nerves, located in the chest. This minimally invasive approach allows for relatively quick healing and recovery time. Recent advancements in imaging and instruments have also improved the precision of the procedure.
