The surgical treatment of carpal tunnel syndrome is done under locoregional anesthesia. It is done on an outpatient basis and takes about 1min.
The classic procedure begins with a small incision (3 to 4 cm) in the palm of the hand. This technique allows the orthopedic surgeon to cut the ligament, enlarge the canal and free the nerve.
Another technique can be performed under endoscopy. The surgeon makes one or two incisions of about 1 cm in the wrist and palm. This technique allows him to cut the flexor tendons in order to free the median nerve.
It is up to the surgeon to decide which technique is best suited to your case.
