I have been experiencing an unfortunate complication from the removal of a large jaw implant. My lower lip is sagging and I have a deep mental crease possibly due to a loss of support in my mentalis muscle. I've had the muscle repaired a couple of times, but it only lasts about 6 weeks or so, and then my lower lip reverts to a low position as before. Is it possible to regain a little improvement if I were to fill the deep crease?
