Corrective Jaw Surgery/Orthognathic Surgery

Orthognathic surgery is also known as corrective jaw surgery. It is used to treat a variety of facial and jaw abnormalities in which the facial bones and teeth are not correctly developed. This results in difficulty with chewing, speech, and jaw function. In many cases, the facial appearance is affected by this problem. Orthognathic means "straight jaws", and orthognathic surgery corrects these jaw and facial deformities, usually in conjunction with an orthodontist, so that after the jaws are corrected, the teeth will come together properly.

Sometimes, braces alone can correct a problem with the bite, but when it is severe, usually orthognathic surgery is required. Abnormal jaw and facial development can be genetic or acquired due to disease or injury. When the jaws are not properly developed or proportioned, problems such as difficulty chewing, jaw and facial pain, speech abnormalities and dental problems can result. Using sophisticated surgical techniques, the facial bones can be repositioned in order to restore proper function and facial appearance.

In the past, thin wires were used to support the bones in the new positions, necessitating the jaws to be wired together. Oftentimes this can now be avoided, with miniature titanium plates and screws which are used to fixate the facial bones in their new relationship.

This, in combination with new instruments and anesthetic techniques, has allowed orthognathic surgery to be safer and more effective, and is much easier for the patient to undergo. New advances in orthodontics have also allowed the total treatment times to be shortened.

If the upper jaw is in normal position, but the lower jaw is retruded, the lower jaw is brought forward to its proper position. Small screws hold the bones in their new positions.

Sometimes, the problem is in both the upper and lower jaws. Here, the upper jaw is brought down and forwards, and the lower jaw is moved back. A combination of plates and screws stabilize the surgical

Orthognathic surgery is performed in the hospital or outpatient surgical center. Patients generally stay in the hospital 1-2 nights, depending on the extent of surgery done. Most patients state that the post-operative discomfort is much less than they were expecting. Almost all patients agree that they are happy with the results and would go through the surgery again, without hesitation. The improvement in jaw function and facial appearance is remarkable. Most patients experience a great improvement in their self-confidence and quality of life after orthognathic surgery.
