The surgery is done to correct problems of the jaw. It may change how the jaw works or repair damage. The jaw is the platform for the teeth. Certain jaw problems make it hard for the upper and lower teeth to line up as they should. This could lead to:
The jaw may also need repairs due to one of the following:
The surgery may also be done to change the appearance of the face. It may be used for receding chin, protruding jaw, or lips that don’t meet.
Problems from the procedure are rare, but all procedures have some risk. Your doctor will review problems that could happen such as:
Factors that may increase the risk of problems include:
Talk to your doctor about these risks before the procedure.
Your teeth may need to be adjusted before surgery. This will help to make sure they are in line with the new jaw. You may need several months of dental care. Braces or similar tools may be used to help shift your teeth into the right position.
An x-ray and models of your teeth may be done closer to surgery. This will help guide work in surgery.
Talk to your doctor if you take any medicine, herbs, or supplements. You may be asked to stop taking some medicine up to 1 week before the procedure.
You may be asked to not eat or drink anything starting the night before your surgery.
General anesthesia will be used. It will block pain and keep you asleep through the surgery.
The exact steps will depend on your specific needs. Most cuts will be made inside the mouth.
Repairs to the bone may include:
The bones will be adjusted until the upper and lower teeth are lined up.
The incisions may be closed with stitches or a glue-like liquid. Gauze may be placed over the surgical wounds. The gauze will stay in place for a few hours after surgery. Rubber bands may be used to help keep your jaw in the right place. They are attached to appliances on the teeth.
After the operation, you will be taken to the recovery room. A care team will help you wake up and check your vital signs. The gauze may be removed when you wake up.
Ice may be placed around your jaw to decrease swelling.
The length of surgery will depend on the needs. It may be 2-4 hours.
Anesthesia prevents pain during surgery. As you recover, you will have some pain. Your care team will give you medicine to help manage any pain.
You may need to stay in the hospital for 2-5 days. If you have any problems, you may need to stay longer.
You will likely need to start with a liquids or soft food diet. As the jaw heals you will slowly be returned to your normal diet. The schedule will depend on how much work was done. A dietitian will help with meal planning.
Some activities will need to be avoided until the jaw is healed.
Contact your doctor if your recovery is not progressing as expected or you develop complications, such as:
If you think you have an emergency, call for emergency medical services right away.
