Does masseter reduction involve removing full thickness of the muscle, or is it possible just to remove the outer layer? (photo)

For mandibular reduction, a portion of the mandibular angle is removed with custom guides, and the masseter muscle is not altered. In some cases, I diminish the inner surface of the masseter with cautery but this is kept to a minimum. It is important for the masseter to reattach to the bone for function and aesthetics.
