Bi-jaw surgery, also known as double jaw surgery, is a corrective procedure where both the upper jaw (maxilla) and lower jaw (mandible) are repositioned. It is performed to correct bite problems, facial asymmetry, sleep apnea issues, or aesthetic concerns.

Who usually needs this surgery?

Patients who have difficulty biting, chewing, or speaking; suffer from jaw pain; have long-term orthodontic issues; or notice a significant imbalance in their facial profile may benefit. It’s often recommended when braces alone cannot fix the problem.

3. Is it only for cosmetic reasons?

No. While improved facial appearance is a welcome benefit, the primary goal is functional – correcting bite alignment, improving speech, breathing, and chewing efficiency.

4. How is bi-jaw surgery different from single jaw surgery?

Single jaw surgery addresses only the upper or lower jaw. Bi-jaw surgery is done when both jaws are misaligned, ensuring harmony between the jaws and facial profile.

Will my face look different after the surgery?

Yes, but positively. Many patients notice a more balanced facial appearance, improved smile, and better profile. The extent of change depends on your existing jaw structure and surgical plan.

How long does the recovery take?

Initial healing takes 3–6 weeks, but complete bone healing usually requires 3–6 months. Most patients resume normal daily activities within a few weeks, with precautions.

Is bi-jaw surgery painful?

The surgery is done under general anesthesia, so you won’t feel pain during the procedure. Post-surgery, there can be swelling, discomfort, and numbness, which are managed with medications and gradually improve.

Will I need braces before and after the surgery?

Yes, in most cases. Braces are used before surgery to align teeth in preparation for jaw movement, and after surgery to fine-tune the bite.

Can bi-jaw surgery help with sleep apnea?

Yes. By repositioning the jaws, the airway can be widened, significantly improving or even curing obstructive sleep apnea in some patients.

Are the results permanent?

Yes. Once the bones heal in their new position, the changes are stable and permanent. Long-term follow-up with your surgeon and orthodontist ensures the best outcome.

What are the risks involved?

Like any major surgery, there are risks such as infection, bleeding, nerve injury (causing temporary or rarely permanent numbness), or relapse of jaw position. However, with modern techniques and proper care, complications are rare.

Will I have scars on my face?

No. All incisions are made inside the mouth, so there are no visible external scars.

How soon can I eat normally after the surgery?

You’ll start with a liquid diet, progress to soft foods, and gradually return to normal chewing in 6–8 weeks depending on healing.

Is there an age limit for bi-jaw surgery?

It’s usually recommended after growth is complete (around 17–18 years). There is no strict upper age limit as long as the patient is healthy.

How do I know if I am a good candidate?

A consultation with an oral & maxillofacial surgeon is essential. Through clinical examination, imaging, and orthodontic evaluation, a personalised treatment plan will be created.
