Orthognathic Surgery

Orthognathic surgery may also be known as corrective jaw / facial surgery. Orthognathic surgery addresses conditions / jaw deformity that may be due to either developmental or traumatic factors.


Such conditions may present as jaw / facial overdevelopment, underdevelopment or facial asymmetry. This can sometimes contribute to problems chewing, breathing (obstructive sleep apnoea), swallowing or pain.

Orthognathic surgery is carried out in conjunction with orthodontic treatment and is part of a treatment regime designed to achieve a balance between the cosmetic appearance of the jaws, facial bones  and a functional occlusion (bite).


What is involved

You will require referral from your orthodontist, dentist, local doctor or physician.

You may need a number of consultations to:

  • Determine the problems you are experiencing, or may experience as a result of your jaw deformity
  • Diagnose these problems
  • Discuss the diagnosis, treatment options and treatment plan
  • Clinical examination and discussion
  • X-rays
  • Photographs
  • Dental models
  • Computer imaging

Treatment planning involves:

  • Clinical examination and discussion
  • Imaging as required (such as plain radiographs and/or CT scan and/or Bone Scan or other special investigation
  • Photographs
  • Dental models
  • Computer imaging

A joint consultation with your referring doctor and you may also be required.

About the Surgery

Prior to undertaking any surgery you will be fully informed of all aspects of your treatment and have the benefits and risks of orthognathic surgery explained.

The surgery is carried out in hospital and involves a stay of approximately 2-5 days. All aspects of this are discussed with you before surgery. The duration of surgery and the period off work vary with the complexity of the surgery.

If you are privately insured we advise you check with your private health insurance provider if your level of cover will provide a rebate for this type of surgery. Although this surgery is not cosmetic in nature but is to correct a functional and growth abnormality, some private health insurance companies classify it as a plastic surgery procedure and require you to be insured for Plastic and Reconstructive Surgery in order to claim a rebate.
