Lower jaw (mandibular osteotomy). The lower jaw is divided and the front section is moved forward or backward and secured with plates and screws.
Lower jaw surgery, a mandibular osteotomy, can correct:
Receding lower jaw
Protruding lower jaw
The surgeon makes cuts behind the molars and lengthwise down the jawbone so the front of the jaw can move as one unit. The jaw can then be moved to its new position either forward or backward. Plates and screws hold the jawbone together as it heals.
Orthognathic surgery moves your teeth and jaws into positions that are more balanced, functional and healthy. Although the goal of orthognathic surgery is to improve your bite and function, many patients also experience enhancements to their appearance, breathing and speech. Orthognathic surgery can have a dramatic and positive effect on many aspects of your life, and it’s likely that your self-esteem and confidence will be significantly boosted.
Chin surgery (genioplasty). A genioplasty can correct a small chin (deficient chin). A small chin often accompanies a severely receded lower jaw.
Typically, surgeons can alter the jaw and restructure the chin during the same surgery. The surgeon cuts a piece of the chin bone on the front of the jaw, moves it forward, and secures it in a new position with plates and screws.
Benefits of jaw surgery may include the relief of facial pain, headaches, snoring and obstructive sleep disorders, including sleep apnea. While a patient’s appearance may be dramatically enhanced as a result of orthognathic surgery, corrective jaw surgery is performed primarily to correct functional problems.
Orthognathic surgery is performed to correct a wide range of skeletal and dental anomalies, including the misalignment of the jaws and teeth.
In normal jaw alignment, the upper jaw and teeth project slightly further than the lower teeth. Problems arise when the jaws or teeth don’t fit together properly because of the size and alignment of the jaw, or position of the teeth.
Jaw surgery, also known as orthognathic (or-thog-NATH-ik) surgery, corrects irregularities of the jaw bones and realigns the jaws and teeth to improve the way they work. Making these corrections may also improve your facial appearance.
Rhinoplasty is a surgery to change the shape of the nose. Because both breathing and the nose’s shape are interrelated, a rhinoplasty may sometimes be performed not only to change the way the nose looks but also to improve breathing through the nose.
