Orthognathic Surgery & Corrective Jaw Surgery

Orthognathic surgery is needed when jaws don't meet correctly and/or teeth don't seem to fit with jaws. Teeth are straightened with orthodontics and corrective jaw surgery repositions misaligned jaws. This not only improves facial appearance, but also ensures that teeth meet correctly and function properly.

Who Needs Orthognathic Surgery?


People who can benefit from orthognathic surgery include those with an improper bite or jaws that are positioned incorrectly. Jaw growth is a gradual process and in some instances, the upper and lower jaws may grow at different rates. The result can be a host of problems that can affect chewing function, speech, long-term oral health and appearance. Injury to the jaw and birth defects can also affect jaw alignment. Orthodontics alone can correct bite problems when only the teeth are involved. Orthognathic surgery may be required for the jaws when repositioning in necessary.

Difficulty in the following areas should be evaluated:

  • difficulty in chewing, biting or swallowing
  • speech problems
  • chronic jaw or TMJ pain
  • open bite
  • protruding jaw
  • breathing problems

Any of these symptoms can exist at birth, be acquired after birth as a result of hereditary or environmental influences or as a result of trauma to the face. Before any treatment begins, a consultation will be held to perform a complete examination with x-rays. During the pre-treatment consultation process, feel free to ask any questions that you have regarding your treatment. When you are fully informed about the aspects of your care, you and your dental team will make the decision to proceed with treatment together.

Benefits of Orthognathic Surgery


Below are some of the benefits of orthognathic surgery:

  1. Improved Jaw Function. Orthognathic surgery can improve the function of the jaw, making it easier to chew, speak, and breathe.
  2. Enhanced Aesthetics. Orthognathic surgery can improve the appearance of the face, giving it a more balanced and symmetrical look.
  3. Reduced Risk of TMJ Disorders. Orthognathic surgery can help to reduce the risk of developing temporomandibular joint (TMJ) disorders, which can cause pain and discomfort in the jaw.
  4. Improved Dental Health. Orthognathic surgery can improve dental health by correcting bite problems, reducing the risk of tooth decay, and making it easier to maintain good oral hygiene.
  5. Increased Self-Confidence. Orthognathic surgery can improve a person's self-confidence by correcting facial asymmetry and improving the overall appearance of the face.
  6. Better Sleep. Orthognathic surgery can help to improve breathing during sleep, reducing the risk of sleep apnea and other sleep-related disorders.

Overall, orthognathic surgery can have a significant positive impact on a person's quality of life, improving both their physical and emotional well-being.


Risks and Possible Complications of the Surgery


Below are some of the potential risks and complications of the procedure:


Nerve Damage

One of the most common risks associated with orthognathic surgery is nerve damage. The nerves that control sensation and movement in the face and jaw can be damaged during the procedure, leading to numbness, tingling, or loss of function in the affected area. In most cases, nerve damage is temporary and resolves on its own within a few weeks or months, but in some cases, it can be permanent.



Like any surgical procedure, orthognathic surgery carries a risk of infection. Infections can occur at the surgical site or in other parts of the body, and can be caused by bacteria or other microorganisms. In some cases, infections can be severe and require hospitalization and treatment with antibiotics.



Orthognathic surgery can cause bleeding, which can be severe in some cases. Excessive bleeding can lead to complications such as anemia, shock, or even death. It is important to follow all pre-operative instructions and avoid taking medications that can increase the risk of bleeding.



Swelling is a common side effect of orthognathic surgery, and can be especially pronounced in the face and jaw. Swelling can be uncomfortable and can interfere with eating, speaking, and other daily activities. In some cases, swelling can also lead to complications such as difficulty breathing or swallowing.


Anesthesia Complications

Orthognathic surgery requires general anesthesia, which carries its own set of risks and complications. Anesthesia can cause allergic reactions, breathing problems, or other complications that can be serious or even life-threatening.


Unsatisfactory Results

While orthognathic surgery can have many benefits, there is always a risk that the results will not meet the patient's expectations. In some cases, the surgery may not correct the problem as well as anticipated, or may result in asymmetry or other aesthetic issues.

Orthognathic surgery is a complex procedure that carries a number of potential risks and complications. However, with careful planning, skilled surgical technique, and close post-operative care, many of these risks can be minimized or avoided altogether. It is important for patients to discuss the risks and benefits of orthognathic surgery with their surgeon, and to follow all preoperative and post-operative instructions carefully to ensure the best possible outcome.

In addition, patients should be aware that recovery from orthognathic surgery can be a long and difficult process, and may involve significant pain, discomfort, and lifestyle changes. It is important to have a strong support system in place, and to be prepared for the physical and emotional challenges of the recovery process.

Overall, while orthognathic surgery can be a highly effective treatment for jaw abnormalities, it is important to carefully weigh the potential risks and benefits before undergoing the procedure. With proper planning, preparation, and care, many patients can achieve excellent results and enjoy a significant improvement in their quality of life.

Avoid Strenuous Activities

After orthognathic surgery, you will need to avoid strenuous activities such as exercise and heavy lifting for several weeks. This will help to prevent complications such as bleeding or swelling.


Manage Swelling

Is the procedure safe?

Corrective jaw surgery has been practiced around the world for decades and has a high record of safety. Under the care of a qualified team, it is a safe procedure. However, as with all major surgeries, there are risks involved. Surgical complications such as bleeding, nerve injuries can occur. General anesthesia itself carries some risks, including allergies, abrasion of airways and in very rare cases, even death. 

Will the shape of the face change after the surgery?

Yes. There the shape of the face will change after surgery. In fact, this is often the treatment objective of many patients. 

Can jaw surgery fix my sleep problems?

It depends on what the sleep problems are. Jaw surgery is very effective in treating obstructive sleep apnea, a condition whereby there is airway obstruction during sleep caused by the soft tissue around the throat such as the tongue and soft palate collapsing into the airway. By surgically moving the jaws forward, these soft tissues are also pulled forward away from the airway, thereby eliminating the obstruction of the airway.

Is jaw surgery painful?

As this is a major surgery, some degree of pain is expected. However, with good post operative pain control using analgesics, it is uncommon to have a patient complaining of pain. Most patients do not require painkillers for more than five days after surgery.
