Minimally invasive treatment of hand hyperhidrosis, i.e., thoracoscopic sympathetic trunk dissection, with intraoperative elevation of the hand temperature above 0,5°C, brings about optimal near- and long-term clinical results, and the risk of recurrence of hyperhidrosis is minimized. Since the development of minimally invasive hand hyperhidrosis needle thoracoscopic treatment in my department, more than hundreds of patients with hand hyperhidrosis have been cured, and no recurrence has been found yet. Foreign medical statistics illustrate that the recurrence rate of hyperhidrosis after surgery is about 1%, and the recurrence rate of surgery by experienced surgeons is less than 1%, and the recurrence is related to the surgeon’s proficiency and neurodegeneration. Recurrence is often caused by the inability to completely cut off the nerve due to adhesion or nerve mutation during surgery. The common complications are as follows: 1, compensatory sweating: the sweat of the hands and feet is gone, but the sweat increases in other parts of the body that were less sweaty before the surgery. 2, Pneumothorax. 3, Hemothorax. 4, Subcutaneous emphysema: there is gas accumulation in the subcutaneous tissue. 5.Recurrence. 6, Pain. 7, Hornor’s Syndrome (Hornor’s Syndrome): ptosis, etc. Sweating in other parts of the body may increase after hand hyperhidrosis surgery, that is, the original chest, abdomen, back and other parts of the body that sweat less sweat increased after surgery (in fact, the amount of this increase is the same as most normal people). Generally, the palms of the hands are almost completely sweat-free after surgery, sweating in the arms, armpits, head and face decreases significantly, and sweating in the abdominal back and thighs may increase. As for the feet, sweating may be reduced in 80% of people. This situation is more obvious in the hot summer, but in general does not constitute a big problem, only a few patients have difficulty in tolerating compensatory sweating. It is generally recognized that the extent of sympathetic ganglia disruption during surgery is small and the likelihood of compensatory sweating after surgery is small.
