A reduction of the labial prominence with increase nasolabial angle was noted subsequent to anterior segmental osteotomies. Long term, prospective, methodology sound clinical trials with larger samples are required to provide sufficient information for predicting the soft and hard tissues changes response to anterior segmental osteotomies.
