What Is Endoscopic Carpal Tunnel Release Surgery?
Surgical treatment for carpal tunnel syndrome uses either open surgery or an endoscope, a thin tube that has a camera attached. The surgeon makes a small incision on the wrist or both wrist and palm, then guides the endoscope through to view internal structures. The endoscopic approach minimizes tearing and scarring compared to open surgery.
When Is Endoscopic Surgery Taken Up?
Endoscopic surgery is appropriate in three situations:
- Symptoms persist despite long-term nonsurgical treatment
- Symptoms are severe and restrict daily activities, including loss of hand coordination, weak thumb strength, or persistent numbness
- There is median nerve damage or high risk of damage
What Happens During the Surgery?
The surgeon uses the endoscope to visualize inside the wrist and hand, then divides the transverse carpal ligament (the carpal tunnel roof). This enlarges the tunnel and reduces pressure on the median nerve. Although the carpal ligament grows back with time, the space in your carpal tunnel is now larger and won’t compress the nerve.
After the Surgery
Patients should keep their hand elevated above the heart and move fingers frequently to prevent stiffness and swelling. Recovery typically takes 2-3 months for pinch and grip strength restoration, though advanced cases may need 6-12 months. Light activities like driving and self-care are permitted with a wrist brace or splint for several weeks.
Expected Outcome
Endoscopic surgery allows faster return to daily activities compared to open surgery, with pain and soreness typically resolving within two months.
