What is the difference between open and endoscopic carpal tunnel release?
Carpal tunnel surgery to release the median nerve can be performed both open and endoscopically.
The open carpal tunnel release procedure involves a 3-4cm incision over the carpal tunnel to directly access and incise the transverse carpal ligament under direct vision. The endoscopic carpal tunnel release procedure is a more minimally invasive approach, in which a tube is placed underneath the transverse carpal ligament through 2 small cuts on the wrist and the palm to allow placement of a camera and cutting device. The ligament is then divided under guidance from the camera.
Both procedures are highly effective at relieving carpal tunnel symptoms, with similar long term results at 6 months post surgery. Endoscopic carpal tunnel surgery is associated with faster recovery time and less pain than open procedures in the immediate post operative period due to the smaller incisions used. The choice of surgical method used in often determined by the preference of the patient and surgeon, and can can be discussed fully during your appointment.
