Hand sweating is a fairly common form of functional abnormal localized sweating of unknown origin. Because of ethnic specificity, young people growing up in subtropical regions are particularly prone to this problem. The sweat glands are controlled by the sympathetic nerves, and hand sweating is caused by unexplained sympathetic overstimulation, such as tension, excitement, stress, or abnormal increases in palm sweating due to summer heat. Hand sweating can occur in both men and women, and is quite common among young people of Eastern ethnicity, with a familial pattern of up to 12%. It has been seen in cases where both parents have hyperhidrosis and all four children have varying degrees of hyperhidrosis. Many patients with hyperhidrosis of the palms have a family history, but it is not always passed on to the next generation. Treatment of hand sweating is divided into medical and surgical approaches. The sympathetic nervous system suppressing drugs used in medical treatment often have side effects such as dry mouth or gastrointestinal disorders, making people afraid to take them for long periods of time. Topical medications are not very convenient because they have limited effectiveness and need to be reapplied from time to time. Because of the limited nature of medical treatment, surgical treatment has become the trend. The sympathetic nerves that control the sweat glands in the hands are located in the second and third vertebrae of the thoracic spine, which are about the line of the nipples and a little higher on the sides of the back vertebrae. Traditionally, the surgery is performed by cutting through the center of the back and cutting the bones where the ribs meet the spine, and removing the second and third sympathetic ganglia on both sides. The surgery takes about 2-3 hours, and there is a wound of about 5-7 centimeters after the surgery, which is painful and takes longer to recover, requiring about 3-5 days of hospitalization. There is also a risk of pneumothorax (a life-threatening sequela in which the lungs cannot breathe due to air leakage), which has mostly been replaced by sympathectomy with TV endoscopy. The procedure requires less than an hour to perform, and after recovery from anesthesia, the patient can go home and rest, with a success rate of up to 98%. ”Thoracoscopic thoracic sympathetic nerve dissection” for hand sweating can be done without opening the chest. The incision is tiny, the pain is small, the scar is small and does not affect the aesthetics, generally discharged about 3 days after surgery, most patients immediately after surgery symptoms disappear. The cure rate is high and the return to normal work life is fast. Patients’ pain of several years or decades disappears immediately, and their self-confidence increases rapidly, and they can soon dissolve into normal social life, interpersonal communication and work. Psychometric studies have also found significant improvements in the psychological health of patients after surgery.
