Corrective Jaw Surgery

OG SurgeryWhat is Corrective Jaw Surgery?

Corrective jaw surgery, also known as orthognathic surgery, is a surgical procedure that realigns jaw and teeth.

The objective of orthognathic surgery is the correction of a wide range of minor and major facial and jaw irregularities, and benefits include an improved ability to chew, speak, and breathe. In many cases, an enhanced appearance can also result.

The surgery is performed by an oral and maxillofacial surgeon who will work together with your orthodontist to determine the best treatment plan for you.

The following are some of the conditions that may indicate a need for orthognathic surgery:

  • Chronic jaw pain
  • Excessive wearing of teeth
  • Open bite (space between upper and lower front or back teeth when mouth is closed)
  • Unbalanced facial appearance
  • Facial injury or birth defects
  • Receding chin
  • Protruding jaw
  • Inability to make lips meet without effort
  • Chronic mouth breathing with dry mouth
  • Sleep apnea (breathing problems when sleeping such as snoring, difficulty breathing, etc.)

How can Othognathic surgery help you?

If your dentist or orthodontist has recommended you for orthognathic surgery, it is likely you are a good candidate for the procedure. If you would like to learn more about the procedure and what it would mean for your personal case, we encourage you to schedule a consultation with Dr Mehanna or Dr Yang. As a specialised Oral and Maxillofacial surgeon, with both Dental and Medical degrees you can be assured the best of care.


Usually, patients are in hospital for 1-2 days. You will need to follow a puree or liquid diet for the first two weeks and slowly progress to a normal diet by 6 weeks. At that point, your orthodontist will complete the final subtle adjustments to the bite and complete your treatment.

As with any operation, certain side effects and complication are possible. Fortunately, these are rare but will be explained to your carefully prior to your treatment.
