What Is It?
Maxillary LeFort I surgery is a corrective jaw surgery designed to reposition the upper jaw (maxilla) to improve bite, function, and facial symmetry. It’s often used to treat:
- Open bite or deep bite
- Underbite or overbite
- Long face or short midface
- Facial asymmetry
- Obstructed breathing or sleep apnea related to jaw position
The procedure is frequently combined with orthodontic treatment for optimal outcomes.
Procedure Overview
- Anesthesia & Access
The surgery is performed under general anesthesia in a hospital or surgical center. An incision is made inside the mouth above the upper teeth, so there are no visible scars. - Jaw Repositioning
The maxilla is carefully mobilized and moved into the new, corrected position—forward, backward, up, down, or rotated, based on your treatment plan. - Fixation
Once in the new position, the upper jaw is stabilized with small titanium plates and screws that remain in place permanently. - Closing & Recovery
The incision is closed with dissolvable stitches. Patients usually stay one night in the hospital for monitoring and supportive care.
Before & After
Frequently Asked Questions (FAQ)
Q: Will I be wired shut after surgery?
A: No, most patients are not wired shut. Small rubber bands may be used temporarily to help guide jaw movement during healing.
Q: Is the surgery painful?
A: You’ll be under general anesthesia during the procedure and prescribed medication to manage discomfort afterward. Most patients report swelling and soreness, but minimal pain.
Q: How long is the recovery?
A: Initial recovery takes 2–3 weeks, with most swelling resolving in about a month. Full bone healing can take 3–6 months.
Q: Will my appearance change?
A: Yes, for the better. While the changes are often subtle, many patients notice improved facial balance, lip support, and smile aesthetics.
Q: Will I need braces before and after surgery?
A: In most cases, yes. Orthodontic treatment ensures your bite aligns properly once the jaws are repositioned.
