Endoscopic Release Surgery

Endoscopic surgery is the newest technique for treating carpal tunnel syndrome. Using narrow instruments and a tiny video camera, your doctor can perform the necessary surgery through a smaller incision than in open surgery. If appropriate for you, this technique may cause less discomfort and allow you to heal faster.


  • Make your doctor aware of any allergies you have, especially to medications or latex.
  • Do not take aspirin or any product containing aspirin, ibuprofen or Vitamin E for two weeks before your surgery, unless directed by your doctor.
  • The night before and the day of your surgery, scrub your hand with an antibacterial soap for several minutes. Trim your fingernails and scrub them with a nail brush. Do not wear rings, nail polish, or artificial nails.
  • Bring someone with you to drive you home.


  • Your preference and your situation dictate the level of anesthesia that is right for you. We want you to be as comfortable as possible. Generally, the more anesthesia you have, the longer you must stay at Dartmouth-Hitchcock to recover, but you will go home the same day.
  • If you want, you may be given something to help you relax.
  • General anesthesia is an option that puts you to sleep during the procedure.
  • More common options are local or regional anesthetics, which numb your hand or arm but do not put you to sleep. You may feel pressure, but will not feel pain. We can give you more anesthesia later if needed.

The procedure

  • The entire procedure generally takes less than an hour.
  • A tight tourniquet will be placed around your arm to help prevent bleeding.
  • Your doctor will make a small incision in your palm or wrist, and insert the endoscope (camera) and surgical instruments. Viewing the ligaments on a monitor, your doctor releases the ligament, removes the instruments, and stitches the incision closed. Your hand is bandaged and you are allowed to recover while the anesthesia wears off.
  • In rare cases, once surgery has begun, your doctor may discover that it is necessary to perform open surgery instead of endoscopic surgery.


  • Your nurse will discuss post-operative care with you. You will receive written instructions, and make an appointment for a follow-up visit.
  • If you need medication for pain, take Tylenol (acetaminophen) or the medication your doctor has prescribed you.
