Types of Corrective Jaw Procedures

Corrective jaw surgery isn’t a single procedure done in the same manner to all patients with jaw issues. Instead, surgeons take on a wide variety of approaches and strategies to align the jaw, all dependent on the patient’s medical history, health conditions, and ideal outcome. For example, orthognathic surgery to fix a misaligned bite will be quite different from orthognathic surgery to treat a sleep apnea patient.

Common types of jaw surgery that we perform:

• Upper Jaw Surgery (Le Fort Osteotomy). The three types of Le Fort Osteotomy, Le Fort I, Le Fort II, and Le Fort III, all involve sectioning and realigning the upper jaw (maxilla) to improve the patient’s condition. These operations are often the treatment of choice for patients who suffer from cleft palate, an underdeveloped upper jaw (mid-face hypoplasia), or upper jaw fractures.

• Lower Jaw Surgery (Bilateral Sagittal Split Osteotomy). In this procedure, the lower jaw (mandible) is sectioned and split before it is re-positioned to better align the teeth and jaw. In some cases, this involves moving the jaw bone backward, while in others it involves moving the bone forward.

• Sleep Apnea Surgery (Maxillomandibular Advancement). There is an innovative sleep apnea surgery that involves moving both the upper and lower jaw forward in order to widen the patient’s airway and make breathing at night easier. This surgery, called Maxillomandibular Advancement (MMA), has a success rate of over 90 percent.

• Chin Surgery (Genioplasty). This procedure re-positions or reforms the chin in order to correct a receding or jutting chin. Chin surgery may involve moving the lower jaw bone, using a chin implant, or cutting away bone in the chin area to reshape a large chin. Chin surgery is sometimes done in addition to other procedures in the mouth, neck, nose, and face area.

In all cases, we use state-of-the-art 3D imaging technology in order to better understand the exact position of our patient’s jaw as well as the very best way to correctly align the teeth and jaw. We refer to these images before, during, and after your operation.

Could Corrective Jaw Surgery be Right for You?

Often, a patient’s very first question is: How do I know if I could benefit from corrective jaw surgery?

The answer is: By speaking with an experienced, knowledgeable oral and maxillofacial surgeon about your condition. Together, perhaps with the help of your dentist and orthodontist, we can find a treatment plan that will work for you.
