Orthognathic surgery is a form of surgery to correct facial and skeletal problems (malocclusions). Skeletal malocclusions often have a large influence on the teeth and in some instances orthognathic surgery is the ideal treatment approach.
Orthognathic surgery and orthodontics are usually performed together. The surgery is performed by an oral and maxillofacial surgeon whilst the orthodontics is performed by an orthodontist. There are many benefits of orthognathic surgery including the repositioning of the jaws in the correct position to enable better function and bite, as well as an improved facial appearance. There are also risks with any surgery (however these risks are normally well managed). Ask your orthodontist if surgery is correct for you or your child.
