This type of surgery is known as orthognathic and is designed to move the upper jaw or maxilla into a better position to correct a malocclusion and restore facial balance.
Surgery can move the upper jaw forward or backwards, or can lengthen/shorten or widen it. Top jaw surgery is performed under general anaesthesia for about an hour and a half. It can be combined with lower jaw or chin point surgery.
There is usually a hospital stay of one or two nights.
