What Are the Long-Term Effects of Orthognathic Surgery?
Understanding the long-term impact helps you make an informed decision. Here is what patients can expect years after surgery.
Orthognathic surgery has lasting positive effects on both function and appearance. Here is what the research shows:
- Positive long-term effects:
- Improved chewing function β permanent and life-changing for most patients
- Better breathing β particularly if the airway was opened
- Reduced wear on teeth β proper bite alignment protects teeth
- Stable facial appearance β the result is permanent
- Improved quality of life β patients report lasting satisfaction
- TMJ symptoms β often improve, though results vary
- Sleep apnea β long-term cure rates of 85β95% with MMA
- What changes over time:
- Facial aging β the jaw changes are permanent, but normal aging continues. Your face will age naturally
- Weight changes β significant weight gain or loss can affect facial appearance over the new jaw position
- Dental changes β teeth may shift very slightly over time with normal aging
- Hardware β titanium plates remain in place permanently and rarely cause problems
- Minimal long-term risks:
- Hardware removal (needed in less than 5% of cases, usually only if it causes irritation)
- Late relapse (minor β usually less than 2 mm over 10+ years)
- TMJ changes (some patients develop symptoms years later, unrelated to surgery)
Long-Term Satisfaction
Studies show 85β95% of patients remain satisfied with their result 5+ years after surgery. Most say it was worth the recovery.
Clinical Guidance
The effects of orthognathic surgery are permanent. Patients enjoy lasting improvements in chewing, breathing, and appearance. The titanium hardware stays in place with minimal long-term issues. Normal aging continues, but the skeletal correction is stable for life.
