Surgeon explaining double jaw surgery

Double Jaw Surgery offers a comprehensive solution for correcting jaw misalignments, significantly improving both functional and aesthetic aspects of the jaw and face.

In this article, we will discuss the features of double jaw surgery. We will explain in detail the purposes, reasons, benefits, risks, and expected recovery process of this corrective jaw surgery.

Understanding Corrective Jaw Surgeries

Orthognathic surgery, popularly known as jaw surgery, is a specialized medical procedure for jawline correction.

This surgery can target different parts of the jaw structure, including:

  • The upper jaw (maxilla)
  • The lower jaw (mandible)
  • Both the upper and lower jaws (bimaxillary surgery)

If the surgery addresses both the upper and lower jaws, we call it double jaw surgery or bimaxillary osteotomy. It is also called bimax surgery or bimaxillary surgery among the public.

Orthognathic surgery has two main purposes:

  • Improve jaw function
  • Aesthetic appearance.

The surgical approach may involve repositioning either or both jaws. In some cases, bone segments may need to be removed to achieve the desired result.

Types of Orthognathic surgery

There are different types of jaw surgeries depending on patient needs. These include:

Le Fort I Osteotomy:

It is a type of oral surgery, focused on correcting irregularities of the upper jaw (maxilla). It is named after René Le Fort, a French surgeon who classified facial fractures.

Bilateral Sagittal Split Osteotomy (BSSO):

Bilateral Sagittal Split Osteotomy is a usual oral surgery in orthognathic surgery. Surgeons do it to fix lower jaw problems. In this surgery, they cut carefully on both sides of the lower jaw. This lets them move the jaw to a new place.


Genioplasty is designed to modify the chin’s shape and position for a more balanced facial appearance.

Bimaxillary Osteotomy:

It is a combination of Le Fort I Osteotomy and BSSO. Bimax Osteotomy alters both the upper and lower jaws for a comprehensive correction.

Maxillofacial Surgery Stats

Maxillofacial surgeries maintain their place in the top five among Reconstructive Procedures, according to the 2022 ASPS (The American Society of Plastic Surgeons) Procedural Statistics report. More than 50,000 Maxillofacial surgeries were performed in the USA in 2022.

The success rate of bimax surgery is approximately 95%, resulting in improved facial aesthetics and functional outcomes.

What Is Double Jaw Surgery?

Double jaw surgery or Bimaxillary surgery, is a surgical procedure that aims to correct misalignment or deformities of both the upper jaw and the lower jaw. It addresses issues related to the structure, position, and function of the jaws and facial bones.

Double Jaw Surgery Procedure

Bimaxillary surgery is a versatile surgical procedure. It aims to correct upper and lower jaw disorders.

Detailed breakdown of the process:

Consultation and Planning:

Before the surgery, a comprehensive consultation is held with the maxillofacial surgeon and orthodontist. Advanced imaging techniques such as 3D CT scans are used to evaluate jaw structure. In this way, a detailed surgical plan is created based on patient needs.

Pre-surgical Orthodontic Treatment:

Patients usually undergo orthodontic treatment before surgery. This step helps align the upper teeth and lower teeth in the correct position. It can range from a few months to a couple of years, depending on the individual’s needs.


The surgery is performed under general anesthesia.
Surgical Access: The surgeon makes an incision inside the mouth. That minimize visible external scars. This gives the surgeon access to the jaw bones.


The surgeon makes precise jaw bone cuts in the upper jaw (maxilla) and the lower jaw (mandible). This allows for the free movement and repositioning of these jaw segments.

Jaw Correction:

The surgeon moves the misaligned jaw segments into their pre-planned, new jaw positions. This step is crucial for addressing facial asymmetry and achieving the desired facial aesthetics.


Once the jaws are aligned, they are held in place using titanium plates and screws. These fixtures provide stability and aid in the healing process.

Additional Procedures:

Depending on the patient’s requirements and the surgeon’s guidance, additional procedures like genioplasty (chin reshaping) might be performed. In this way, overall facial harmony can be achieved.

Wound Closure:

The surgeon carefully stitches the incisions inside the mouth. They make sure the wound is properly closed.

Recovery Period:

After the surgery, patients are closely monitored in a recovery room. Once stable, they might be required to stay in the hospital for 2-4 days. During recovery, you need a soft diet. Take the medicines your doctor gives you. And go to regular check-ups to keep an eye on how you are healing.

Post-surgical Orthodontic Treatment:

After the surgery, you might need more dental treatments to adjust your teeth’s alignment and make sure your bite works well.

These steps give a basic idea of what happens in bimaxillary surgery. It’s important to remember that the details can change depending on your situation and the surgeon’s specific approach.

Benefits of Double Jaw Surgery

The jawline problem causes visible problems in facial asymmetry and facial aesthetics. Double jaw surgery eliminates facial asymmetry caused by jaw problems.

Bimax surgery has many benefits that can improve the patient’s quality of life. These include:

Correct Jaw Misalignment:

It resolves open bite problems like underbites, overbites, and crossbites. Also jawline correction improves your facial asymmetry.

Types of jaw misalignment:

  • Deep overbite
  • underbite
  • open bite
  • jaws that overlap sideways
  • jaws that meet at the wrong angle (asymmetric jaws)

Correct Jaw Size:

The procedure adjusts the size of the jaws to achieve proportional facial appearance.

Balance Facial Features:

By aligning the jaws properly, the surgery creates a balanced and appealing facial profile.

Improve Jaw Function:

It rectifies chewing, swallowing, and speech issues caused by jaw malformation.

Relieve Facial Pain:

It provides relief from facial pain and discomfort associated with jaw disorders.

Improve Obstructive Sleep Apnea:

The surgery can make the breathing passages bigger, which helps with symptoms of sleep apnea.

Which Surgeon can perform Double Jaw Surgery?

Double jaw surgery is typically performed by an oral and maxillofacial surgeon. These surgeons specialize in surgery of the mouth, jaws, and face and have extensive training in these complex procedures. In some cases, a team involving both an oral and maxillofacial surgeon and a plastic surgeon may be involved, depending on the specific requirements and goals of the surgery.
