Services Corrective Jaw Surgery (Orthognathic Surgery)

Corrective jaw surgery improves the lower & upper jaw relationship. Problems may either be because of developmental or trauma issues. Surgery may be on the upper or lower jaw (single jaw surgery) or both jaws (bimaxillary surgery). It involves carefully placed cuts in the bone, known as an osteotomy. The most common osteotomy performed on the lower jaw is the bilateral sagittal split osteotomy. The most common on the upper jaw, is the Le Fort I osteotomy. An osteotomy moving the chin alone, is known as a genioplasty.

Corrective jaw surgery usually involves orthodontic treatment by an orthodontist, both before and after the surgery. When someone has a jaw discrepancy, the teeth in the jaw, are often in the wrong position. The orthodontist moves the teeth into the correct position in each jaw and the jaws are moved into their correct relationship to each other.

A thorough examination and history is taken and investigations performed, where the surgey's nature, risks and benefits are discussed. The patient then makes informed consent as to whether or not to have the surgery.
