What Double Jaw Surgery Is and What You Can Expect

Double jaw surgery is also known as Bi-maxillary Osteotomy. It is a specific type of orthognathic or corrective jaw surgery. Often, oral surgeons perform surgery on one jaw at a time. Double jaw surgery is when they perform surgery on both jaws simultaneously. Double jaw surgery aims to correct both aesthetic and functional skeletal issues. A common condition double jaw surgery addresses is a protruding jaw, which causes an abnormal bite, called a malocclusion.

The oral surgeon will resize, reshape, and reposition the entire jawbones to give the patient the most favorable outcome.

Who Needs Double Jaw Surgery?

Double jaw surgery is recommended for those with severe jaw alignment issues. Double jaw surgery is often recommended after orthodontic treatment does not work to correct skeletal structural problems. Double jaw surgery is recommended for patients who have had facial trauma or surgery. Here are other reasons why someone might need a double jaw surgery:

People who have an abnormally long face or chin.
People who have lantern (square) jaw with malocclusion (an incorrect relation between the teeth of the two dental arches when they approach each other as the jaws close).
People who have a protruding mouth.
Sleep conditions, such as obstructive sleep apnea, can result from various facial structural issues and can be corrected to improve quality of life.

What to Expect From a Double Jaw Surgery

Double jaw surgery requires the use of general anesthesia. It is performed under the guidance of an oral and maxillofacial surgeon. The surgeon makes incisions on both sides of the face. The surgeon will then perform the necessary osteotomies to realign the jaw. There is significant post-operative swelling and bruising. Your doctor will place a splint on the face to help straighten the jaw, and then you will be released to go home.

The jaw will be wired shut at least for a week. The wires will be removed, and you will be allowed to eat soft solid foods. The jaw will be wired shut again for another 2-3 weeks. You will not be able to talk or chew solid food. You will be required to see the surgeon weekly during the healing process. Sometimes you may need to have the wires changed or adjusted. The splint will eventually be removed, and you will be allowed to eat soft solid food. There is some risk of infection and jaw fractures.

After the operation is complete, the doctor will go through what you can expect in terms of recovery time and care. After a few weeks, you may need to follow up with the surgeon to make sure there is no infection. As a result, the recovery time for double jaw surgery can be long. It will take several months before the jaw returns to its normal state.


Choosing the right surgeon will help you achieve the best results. Double jaw surgery is not simple, especially when two jaws are affected. Never go to a surgeon who offers this surgery if they are not board-certified by the American Board of Oral and Maxillofacial Surgery.
