Problems from the procedure are rare, but all procedures have some risk. Your doctor will review problems that could happen such as:
- Numbness or pain in sinuses, ears, or teeth
- Excess bleeding
- No improvement in symptoms
- Poor cosmetic outcome
- Adverse reaction to anesthesia, such as lightheadedness, low blood pressure, and wheezing
- Nausea and vomiting
Factors that may increase the risk of problems include:
- Bleeding disorders
- Chronic health conditions, such as heart disease
Talk to your doctor about these risks before the procedure.
Reasons for Procedure
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:
- Difficultly chewing or biting
- Speech problems
- Breathing problems
- Problems breathing during sleep, such as sleep apnea
- Jaw pain
The jaw may also need repairs due to one of the following:
- Facial injuries
- Birth defects
- Genetic conditions
- Bone disease or conditions that affect bone growth
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.
What to Expect
Prior to 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.
Description of the Procedure
The exact steps will depend on your specific needs. Most cuts will be made inside the mouth.
Repairs to the bone may include:
- Removing a section of bone
- Separating a section of the jaw so that is can be moved backward or forward
- Reattaching the new edges of bone with metal plates, screws, or wires
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.
Immediately After Procedure
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.
How Long Will It Take?
The length of surgery will depend on the needs. It may be 2-4 hours.
How Much Will It Hurt?
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.
Average Hospital Stay
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.
- You will be able to notice cosmetic change right away.
- Your jaw will need to heal before you can do normal movements. It may take some time to feel the improvements in bite or jaw movement.
Some activities will need to be avoided until the jaw is healed.
