[Rosemont, IL, October 1, 2014] Corrective jaw surgery is the treatment of choice for improving facial appearance by correcting a protruding or underdeveloped jaw and other abnormalities of the facial skeleton. Such surgery also helps fix improperly aligned upper and lower teeth. While most patients who opted for this surgery in the past were in their 20s or 30s, more recently patients over 40 have become aware of improvements in these jaw surgical techniques and the resulting improved facial appearance and jaw function.
