Your doctor may offer surgery if nonsurgical treatment fails to relieve your symptoms or only gives temporary relief. The following factors are considered while deciding whether or not to recommend surgery:
- Your symptoms' seriousness
- The results of the physical examination
- The patient's reaction to non-operative treatment
- The results of the tests
Surgery may be needed to prevent permanent damage in long-term situations of continuous numbness and atrophy of the thumb muscles. If non-operative treatments fail to provide relief and/or testing reveals severe nerve alterations, surgery may be suggested.
Release the carpal tunnel - Your doctor makes a small incision in the palm of your hand and looks into your hand and wrist through it during open carpal tunnel release surgery. Your doctor will divide the transverse carpal ligament during the treatment (the roof of the carpal tunnel).
This opens up the tube, allowing the median nerve to be relieved of pressure. The ligament may gradually extend as a result of surgery, but there will be greater space in the carpal tunnel and pressure on the median nerve will be eased.
Carpal tunnel syndrome is treated with an endoscopic procedure - Your doctor will create one or two small skin incisions (called portals) and use a little camera, or endoscope, to look inside your hand and wrist during endoscopic surgery. Similar to the open carpal tunnel release operation, a specific knife is used to separate the transverse carpal ligament. Open surgery and endoscopic surgery produce similar results. Both the procedures have their own set of advantages and drawbacks. Your doctor will discuss the best surgical procedure for you with you.
