What Exactly Is Double Jaw Surgery?

Double Jaw Surgery

Bi-maxillary Osteotomy is another name for double jaw surgery. It is a type of corrective jaw surgery called orthognathic surgery. Most of the time, oral surgeons work on one jaw at a time. When someone has double jaw surgery, they do surgery on both jaws at the same time. The goal of double jaw surgery is to fix both the way the bones look and how they work. A common problem that double jaw surgery fixes is a jaw that sticks out. This makes it hard to bite, which is called a malocclusion.

The oral surgeon will change the size, shape, and position of all the jaw bones to give the patient the best possible result.

Who Needs Surgery for a Double Jaw?

Double jaw surgery is not a way to look better. People who need double jaw surgery have mouth and jaw problems that are bothersome because of their genes or other conditions.

People with faces or chins that are too long

People who have a protruding jaw

People whose teeth don’t fit together well because their bones aren’t right

Sleep problems, like obstructive sleep apnea, can be caused by the way your face is built and can be fixed to improve your quality of life.

How do oral surgeons do surgery on a double jaw?

Oral surgeons do double jaw surgery in a hospital with general anesthesia, and it can take anywhere from three to four hours, or even longer. For surgery on the lower jaw, they may use one of two methods, and for surgery on the upper jaw, they usually only use one method. A Sagittal Split Osteotomy is the first choice for the lower jaw. With this method, the back of the jaw is cut in half diagonally on both the left and right sides. The surgeon can then move a lower jaw that sticks out in back or a lower jaw that sticks out in back forward to make the bite better. After that, titanium screws and sometimes plates are used to hold the lower jaw in place. This is the most common method because the pieces are fixed firmly and the patient won’t have to have his or her jaw wired shut for a long time.

The second way to fix the lower jaw is through an Intra-oral Vertical Ramus Osteotomy. With this method, the surgeon makes vertical cuts in the back of the lower jaw so that the lower jaw can be trimmed and moved backward. Since this method can move the jaw without using wires or pins, the patient will have to have his or her teeth wired shut for several weeks while the jaw heals. This makes it less likely that you will have jaw joint pain or other problems. This method requires a very skilled oral surgeon because there isn’t much room for error during the procedure.

The surgery to separate the upper jaw from the skull is called a Lefort osteotomy. During this surgery, a cut is made across the upper jaw bone above the tooth roots. The upper jaw is then put back where it should be, and titanium plates and screws hold it in place.

How long does it take to heal?

How long it takes to get better after double jaw surgery depends on the method used by the oral surgeon. Most bones take between 4 and 6 weeks to heal on their own. The patient’s teeth are usually wired shut for one to three weeks, after which they wear guiding elastics.
