Your lung on this side is deflated (collapsed) so that air does not move in and out of it during surgery. This gives the surgeon more room to work. A tiny camera called an endoscope is inserted through one of the cuts into your chest. Video from the camera shows on a monitor in the operating room. The surgeon views the monitor while doing the surgery. Other small tools are inserted through the other cuts. Using these tools, the surgeon finds the nerves that control sweating in the problem area. These are cut, clipped, or destroyed. Your lung on this side is inflated. The cuts are closed with stitches (sutures). A small drainage tube may be left in your chest for a day or so.After doing this procedure on one side of your body, the surgeon may do the same on the other side. The surgery takes about 1 to 3 hours. Why the Procedure Is Performed This surgery is usually done in people whose palms sweat much more heavily than normal. It may also be used to treat extreme sweating of the face. It is only used when other treatments to reduce sweating have not worked.

Some of these are aspirin, ibuprofen (Advil, Motrin), and warfarin (Coumadin). Ask your surgeon which medicines you should still take on the day of your surgery. If you smoke, try to stop. Ask your provider for help quitting. Smoking increases the risk for problems such as slow healing. On the day of your surgery:Follow instructions about when to stop eating and drinking. Take the medicines your surgeon told you to take with a small sip of water. Arrive at the hospital on time. After the Procedure Most people stay in the hospital one night and go home the next day. You may have pain for about a week or two. Take pain medicine as your doctor recommended. You may need acetaminophen (Tylenol) or prescription pain medicine. Do not drive if you are taking narcotic pain medicine.Follow the surgeon's instructions about taking care of the incisions, including:Keep the incision areas clean, dry, and covered with dressings (bandages). If your incision is covered with Dermabond (liquid bandage) you may not need any dressings. Wash the areas and change the dressings as instructed. Ask your surgeon when you can shower or bathe.Slowly resume your regular activities as you are able.Keep follow-up visits with the surgeon. At these visits, the surgeon will check the incisions and see if the surgery was successful. Outlook (Prognosis) This surgery may improve the quality of life for most people. It does not work as well for people who have very heavy armpit sweating. Some people notice sweating in new places on the body, but this may go away on its own.Open ReferencesReferencesInternational Hyperhidrosis Society website.
