Hand sweating is a disease caused by exocrine glands that cause excessive sweating, although the cause is unknown, but due to sweaty palms, soles and armpits, sometimes the head, neck, trunk, groin or perineum are also prone to sweating. The sweating is often dripping and can cause embarrassment and hindrance to life and work or social interaction. Non-surgical treatments include astringents, antiperspirants, sedatives, anticholinergic drugs, hypnotherapy, psychotherapy, ECT, and acupuncture, all of which have no clear efficacy except for anticholinergic drugs, but their use is limited by their side effects. Television thoracoscopic thoracic sympathectomy is currently the only effective and long-lasting treatment for hand sweating. In recent years, the surgery has been continuously improved, and now bilateral thoracic third sympathetic nerve trunk dissection is used instead of the traditional thoracic second sympathetic nerve dissection (removal) for surgical disorders, with precise and satisfactory results, significantly reducing the possibility of compensatory hyperhidrosis after surgery.
