What is an Orthognathic Surgery?
Orthognathic surgery, also known as corrective jaw surgery, is a surgical procedure performed to correct abnormalities of the jawbones and associated structures, such as misaligned jaws or facial skeletal discrepancies. These abnormalities can cause functional issues with biting, chewing, speaking, and breathing, as well as aesthetic concerns.
What is The Procedure of an orthognathic surgery?
During orthognathic surgery, the procedure typically involves the following steps
1. Pre-surgical orthodontic treatment
Before the surgery, the patient often undergoes orthodontic treatment to
align the teeth as closely as possible. This helps ensure optimal alignment and stability of the jaws after surgery.
2. Surgical planning
Detailed imaging, such as X-rays, CT scans, and 3D imaging, is used to plan the surgery precisely.
Virtual surgical planning software allows surgeons to simulate the procedure and determine the exact movements
needed to achieve the desired results.
3. The surgical procedure
Orthognathic surgery is usually performed under general anesthesia in a hospital setting.
The surgeon makes incisions inside the mouth to access the jawbones. Depending on the specific needs of the
patient, the surgeon may reposition the upper jaw (maxilla), lower jaw (mandible), or both. Surgical techniques
may involve cutting, repositioning, and securing the jawbones using small plates, screws, or other fixation devices.
4. Recovery and post-operative care
After the surgery, patients typically require a period of recovery, during which
they may experience swelling, bruising, and discomfort. Pain medication and a soft diet are usually prescribed to
manage discomfort during the initial healing phase. Follow-up appointments with both the oral surgeon and
orthodontist are essential to monitor progress and adjust orthodontic treatment as needed.
Who needs an Orthognathic Surgery?
Orthognathic surgery is recommended for patients who
Have severe bite misalignment causing difficulty in chewing, speaking, or swallowing.
Experience jaw deformities impacting facial appearance and function.
Suffer from obstructive sleep apnea due to jaw structure.
Have temporomandibular joint (TMJ) disorders not resolved by other treatments.
Require correction post-trauma or congenital anomalies affecting jaw position.
Frequently Asked Questions
Is orthognathic surgery painful?
Pain is managed with anesthesia during surgery and medications post procedure.
How long is the recovery period?
Initial recovery takes 6–8 weeks, with complete healing over several months.
Will I need braces?
Often, pre- and post-surgical orthodontics are needed to align teeth.
Is the procedure safe?
When performed by a skilled oral & maxillofacial surgeon, it is safe and predictable.
Are results permanent?
Yes, with proper post-surgical care and follow-up, results are long-lasting.
