The Problem

Your teeth and jaws may not be properly aligned, which can affect your bite, facial balance, and sometimes your speech or breathing.
Orthognathic surgery is performed to reposition the upper jaw (maxilla), lower jaw (mandible), or both, to achieve better alignment and facial harmony.
This surgery is done under a general anaesthetic, meaning you will be fully asleep during the procedure.

What Does the Operation Involve?

• The surgery is usually performed inside the mouth, so there are no visible scars on the face.
• Cuts are made in the gum to reach the jawbones.
• The bones are carefully cut and moved into their new, correct positions.
• They are held in place using small metal plates and screws made of titanium.
• The gums are then closed with dissolvable stitches, which may take up to two weeks or longer to disappear.
• X-rays will be taken during and after surgery to check the position of your jaws.

What Can I Expect After Surgery?

• You will have some swelling, tightness, and mild discomfort after surgery. Regular painkillers will be given.
• Swelling usually peaks around days 2–3 and begins to settle after a week or two.
• Keeping your head elevated and using cold compresses can help reduce swelling.
• Some patients notice minor bruising, particularly under the eyes or around the cheeks.
• You will receive antibiotics to reduce the risk of infection.
• You may have some numbness of the lips, cheeks, or tongue after surgery. This is usually temporary but can occasionally be long-lasting.
• The plates and screws are permanent but rarely cause problems and do not trigger metal detectors.

Eating After Surgery

• You will need to follow a modified diet for several weeks.
• Initially, you may be limited to liquids and soft foods, gradually returning to a normal diet as healing progresses.
• Good nutrition is important for recovery—your team will advise you on suitable meal options.

Oral Care

• You should continue to brush your teeth and gums gently with a soft toothbrush.
• Mouth rinses or saltwater rinses may be recommended to help keep your mouth clean.
• Avoid smoking and alcohol during recovery, as they can delay healing.

Hospital Stay

• Most patients stay in hospital for 1–2 nights.
• You will be monitored closely until you are comfortable and able to eat and drink.
• X-rays will be taken before discharge to confirm everything is in the correct position.

Time Off Work or School

• Recovery time varies depending on the complexity of your surgery and your occupation.
• Most people need 2–4 weeks off before returning to work or school.
• Avoid strenuous physical activity for at least 4–6 weeks.
• You must not drive or operate machinery for at least 48 hours after a general anaesthetic.

Possible Complications

While complications are uncommon, it is important to be aware of possible risks:

• Bleeding: Some oozing inside the mouth is normal. Persistent bleeding should be
  reported.
• Infection: Occasionally, the metal plates may become infected and need removal.
• Numbness: Temporary numbness of the lips, chin, or cheeks is common and may take
  months to recover.
• Relapse: In rare cases, small movements of the bones may occur as healing progresses.
• Jaw stiffness: Gentle exercises and time help restore full movement.

Follow-Up Appointments

• You will be reviewed regularly by your surgeon and orthodontist to monitor healing
  and bite alignment.
• X-rays and clinical checks will ensure everything is progressing well.
• Further orthodontic treatment is often required after surgery to fine-tune your bite.

If You Have Concerns

If you experience persistent bleeding, swelling, fever, or difficulty breathing or swallowing,
contact your surgical team or the hospital immediately.
