Jaw surgery, also known as orthognathic surgery, is a corrective procedure that addresses abnormalities in the structure of the jaw. It’s commonly recommended when non-surgical treatments like orthodontics alone aren’t enough to fix serious issues with bite, jaw alignment, or facial appearance قیمت عمل فک. Though it sounds intimidating, jaw surgery can be life-changing—improving not just function, but confidence and quality of life.
What Is Jaw Surgery?
Jaw surgery involves surgically repositioning the upper jaw (maxilla), lower jaw (mandible), or both to achieve better alignment. It’s performed by an oral and maxillofacial surgeon, often working closely with an orthodontist before and after the procedure.
Orthognathic surgery is most often used to correct:
-
Severe bite misalignments (underbite, overbite, crossbite)
-
Jaw size discrepancies (one jaw significantly larger or smaller)
-
Sleep apnea caused by structural issues
-
Chronic jaw pain or temporomandibular joint (TMJ) disorders
-
Facial asymmetry or disproportion due to jaw growth issues
-
Injuries or congenital defects like cleft palate
Signs You Might Need Jaw Surgery
Some signs that jaw surgery may be appropriate include:
-
Difficulty chewing or biting food properly
-
Speech issues related to jaw alignment
-
Jaw pain or popping noises in the joint
-
Breathing difficulties, especially during sleep
-
A visibly misaligned jaw or chin
-
Chronic headaches or facial pain
Types of Jaw Surgery
There are several types of orthognathic surgery, depending on the issue being addressed:
-
Maxillary Osteotomy (Upper Jaw Surgery):
-
Corrects an overbite, open bite, or crossbite
-
Can also fix mid-face height issues or a gummy smile
-
-
Mandibular Osteotomy (Lower Jaw Surgery):
-
Often used to treat underbite or receding lower jaw
-
-
Bimaxillary Osteotomy (Double Jaw Surgery):
-
Involves both upper and lower jaws
-
Common in severe or complex cases
-
-
Genioplasty (Chin Surgery):
-
Sometimes performed alongside jaw surgery to improve facial balance

The Surgical Process: Step by Step
1. Evaluation & Planning:
X-rays, 3D scans, and models of your teeth are used to design the surgery. You may also have braces fitted months before the operation.
2. Surgery:
Performed under general anesthesia, the surgeon cuts and repositions the jaw bones, securing them with plates and screws.
3. Recovery:
Initial healing takes about 6 weeks, but full recovery can take 9–12 months. Patients follow a liquid or soft diet and may need time off from work or school.
4. Post-surgical Orthodontics:
Braces are usually worn for several months post-surgery to perfect the bite.

Risks and Considerations
As with any surgery, jaw surgery comes with potential risks:
-
Swelling and bruising
-
Temporary or permanent numbness (especially in the lower lip or chin)
-

Need for further adjustments or revision surgery
However, with proper planning and a qualified surgical team, complications are rare.
