Jaw Misalignment Surgery helps you chew and speak better by optimising your jaw position. In some cases of Obstructive Sleep Apnea,  it could help you to sleep better. Jaw growth (too forward or backward) is one of the many reasons chewing difficulties or choking during sleep happens. Surgery is needed when  braces alone cannot achieve an ideal bite.

About Risks, Recovery And Diet
Maxillomandibular Advancement (MMA)
treats Obstructive Sleep Apnea effectively, and many patients discontinue CPAP after MMA.
Maxillomandibular Advancement (MMA) is one of the more effective procedures to improve Obstructive Sleep Apnea (OSA) significantly. Obstructive Sleep Apnea (OSA) is related to heart diseases, diabetes, high blood pressure and other serious medical conditions. After diagnosis by a Sleep disorder specialist, treatment options which aims to overcome the airway blockage during sleep include Nasal spray, CPAP or Surgery like MMA or other soft tissue surgeries. MMA improves airway architecture and relieves airway obstruction.
Maxillomandibular Advancement
What is Maxillomandibular Advancement
This surgery technique has been practiced and refined over 200 years. Your airway is improved by optimising jawbone position. This often results in a much better airflow during sleep. Many patients also report improvement in biting functions and appearance.
What Happens Next?

OSA is diagnosed after a sleep study conducted by a Sleep disorder specialist. You can discuss MMA as part of the treatment options of OSA with your sleep specialist.

Consultation for MMA involves a detailed assessment of your skeletal and dental architecture. Adjunctive orthodontics may be discussed as part of the treatment since your biting pattern will change.

A customised plan is developed for you and customised 3D patient specific guides are fabricated for your surgery.

You will wake up from surgery comfortable with your jaw in the new position. Most patients stay 1-2 nights in the hospital. Medicine will be given to keep you comfortable during recovery. You can resume light activities after 1 week.

Other Expectations For MMA
  • There are some modifications to your diet for the first 3 weeks of recovery. These will be discussed with you during consultation. You can also find out more here.
  • Most patients require adjunctive orthodontics to optimise chewing function after surgery.
  • You may find changes to your facial features that may not be noticeable to causal onlookers.
  • Some numbness sensations may result after surgery, but these usually improve over time.
  • Your sleep disorder specialist may repeat the sleep study 6 months after MMA.
