What is orthognathic surgery

Orthognathic surgery is also known as “Corrective Jaw Surgery”. 

The upper jaw, lower jaw or both jaws can be surgically repositioned to correct a malocclusion (or “bad bite”) that is too severe for orthodontic correction and to achieve better facial balance.

Types of Jaw Surgery include:

  1. Upper Jaw Surgery (Le fort 1 Maxillary Osteotomy)
  2. Lower Jaw Surgery (Bilateral Sagittal Split Mandibular Osteotomy)
  3. Chin Surgery (Genioplasty)

Sometimes only single jaw surgery is required. Other times, Two jaw Surgery is needed.  Two jaw surgery is often referred to as “Bimaxillary Osteotomy” and both jaws are operated on at the same time in the one surgery.

The benefits of jaw surgery include improvement of bite function, improvement of facial aesthetics and in some instances improvement of the airway.
