Maxillary osteotomy

What is the Maxillary osteotomy?

Maxillary osteotomy surgery may be advised when an abnormally positioned jaw is giving rise to cosmetic problems. A maxillary osteotomy is performed to correct any of the following issues: significantly receded upper jaw, crossbite, excess or deficiency in upper jaw vertical height (too much or too little tooth-show), open bite (apertognathia). The jaw can be moved upwards / downwards / forwards and rarely backwards.

What is the procedure?

The surgeon makes bone cuts inside the mouth above the teeth and below both eye sockets so the entire top jaw, including the roof of the mouth and all upper teeth, can move as one unit. The teeth and jaw are moved forward until the upper and bottom teeth fit together properly.

Once the jaw is realigned, tiny screws and bone plates hold the bone in its new position. These screws are smaller than a bracket used for braces and become integrated into the bone structure over time.

What kind of result can you expect?

Surgery moves your teeth and jaws into a new position that is more balanced, functional and healthy. Not only should you be able to bite and chew better than ever before, but your appearance and speech may be enhanced, as well.

Recovery period and recommendations

After orthognathic surgery, patients are often required to adhere to an all-liquid diet. Normal recovery time can range from a few weeks for minor surgery, to up to a year for more complicated surgery.

Possible side effects and complications

Like any other surgery, there can be some complications like bleeding, swelling, infection, nausea and vomiting. There are certain complications involved in maxillary ostetomies; devitalisation of teeth, loss of part or all of the osteotomized segment, and relapse are possible problems.
