There are many methods that can be used to perform an osteotomy. In one method, the doctor uses imaging technology to measure the piece of bone that will be removed.

The doctor uses an oscillating saw to remove the bone wedge. The remaining parts of the bone will be held together with staples, screws, or a plate and screws. The doctor will stitch the tissue together and close the area.
Anesthesia will block pain during the procedure. You will have pain after the procedure. Ask your doctor about medication to help manage pain.
