I asked a similar question in a different thread but I managed to confuse the issue- many apologies.
The following is a FAQ item from my surgeon's website, it's about chin reduction:
QuoteQ: Is it possible for the lower lip to move upwards after a chin height reduction? Does the smile change?
A: Yes, if you reduce the height of the chin and you suture the muscle well, the lower lip moves upwards.
Has anyone else heard of this before? Has anyone experienced this as a result of a chin reduction?
Again, apologies for asking twice. I won't do it again- promise.
