What is double jaw surgery or bimaxillary osteotomy?

Double jaw surgery corrects protruding mouth and or receding chin, as well as protruding lips accompanied by malocclusion (overbite / underbite) along with facial asymmetry. It is sometimes known as two jaw or double jaw surgery because of its correction and alignment of the upper and lower jaw.


This surgical procedure corrects protruding or receding chin, protruding lips accompanied by malocclusion as well as facial asymmetry.

The proper position of the chin changes the entire facial skeleton, providing improvements in both function and appearance.

Special features of VIEW’s transparent double jaw surgery (bimaxillary osteotomy)

Natural facial expression

Accurate planning and precise double jaw surgery without even the slightest error perfects a natural facial expression.

Enhanced Professional Expertise

Bone scalpel

This device used for cutting only bones enables a safe and precise surgery without damaging important nerves and blood vessels.

Bone scalpel enhancing the accuracy and safety of surgery
The bone scalpel is an ultrasonic device which cuts the bones by responding only to the bone tissues.

It has less vibration within 0.5mm enabling a very precise surgery, protects nearby blood vessels and nerves by responding only to bones, causes less tissue damages and bleeding and provides quick recovery.


Pre-operational double jaw surgery (bimaxillary osteotomy)

Unlike existing surgeries, the pre-operational double jaw surgery (bimaxillary osteotomy) performs the bimaxillary osteotomy first and then the revision treatment.

It corrects the skeletal problems for quick improvement of looks, realigns the teeth faster, and has a short period of revision.

Fast fixation (no fixation)

Currently, there is no intermaxillary fixation after the bimaxillary osteotomy.

Why there is no intermaxillary fixation
  • It precisely realigns the jaw joint during the surgery. In this case, the operational technique assists the joint to fall in place comfortably.
  • The muscles around the relocated lower jaw are controlled to minimize the force trying to pull the chin back to the position before the surgery.
Advantages of not performing intermaxillary fixation
  • It can reduce discomfort by allowing the patient to breathe through the mouth after the surgery.
  • It can shorten the period it takes to restore bodily functions in ordinary life like speaking or eating.
When you need intermaxillary fixation
  • The rubber band is used to adjust the position if the asymmetry was serious before the surgery or the jaw tends to fall back to the position before the surgery due to strong muscles around the chin. However, you can open your mouth in this case.
  • For people with open bite (The fixation may be required for 2 days depending on circumstances)

When do you need double jaw (bimaxillary osteotomy)?

01If you have a long lower chin or lantern jaw with a protruded lower chin

02If you have a mouth with protruded ulitis and teeth

03If you have a crooked facial center line and facial asymmetry

04If you have a long central facial line

05If your gums shows a lot when smiling

Double jaw surgery method

View Plastic Surgery Clinic’s ‘Nano bimaxillary osteotomy™’ applies the occlusal plane rotation to form a slimmer facial line and natural look with beautiful dentition.

In addition, the clinic selects either the Sagittal Split Ramus Osteotomy (SSRO) or Intraori Vertical Ramus Osteotomy (IVRO) for the mandible (lower jaw) surgery depending on the patient’s symptoms.

bimaxillary osteotomy

The clinic analyzes symptoms for each individual patient and decides the site to be cut.

bimaxillary osteotomy

It applies the occlusal plane rotation to rotate the upper jaw and move it to the right position.

bimaxillary osteotomy

The lower jaw is cut (mandible surgery) to move it to the proper position for the occlusion with the upper jaw.

bimaxillary osteotomy

The fractured bones are firmly fixed not to move.

Occlusal plane rotation for a slim facial line and natural facial expression

It refers to a technique which pushes in the upper and lower jaws by rotating the chin to move to the proper position.

The limitation in the existing double jaw surgery (bimaxillary osteotomy) is that the chin cannot be pushed further inside when there is occlusion However, due to the development of occlusal plane rotation, lantern jaw or long face with dental occlusion can be pushed in to the desired extent.

Facial bone

The lower jaw is cut (mandible surgery) to move it to the proper position for the occlusion with the upper jaw.

Not only the movement (mm) but also the rotating angle (degree) must be considered to apply the occlusal plane rotation during double jaw surgery (bimaxillary osteotomy).

View Plastic Surgery Clinic moves the chin without the slightest error through precise planning and surgery and rotates the upper and lower chins to the precise angle to make a slimmer face and natural facial expression.


Flat nose after double jaw surgery (bimaxillary osteotomy).

The nose and the surrounding area may look wide due to the rearrangement of muscles around the upper jaw while the upper chin was relocated during a double jaw surgery (bimaxillary osteotomy). You can consider having rhinoplasty if you have severe stress about the wide nose after the surgery.

Why View Plastic Surgery Clinic’s double jaw surgery (bimaxillary osteotomy) has been praised.

3Fast fixing

The fast fixation is a short-term fixation procedure for 2 – 3 days to help the chin joints settle in a more stable position.
The joints are fixed with rubber bands rather than metal wires for the free movement of the chin and comfortable breathing, eating and conversation.

43D CT satisfying both precision and safety

It is important to accurately identify the position of the neural gland and understand the bone structure (size, width, thickness, length) due to difficulty in securing a good field of vision during the facial bone surgery.

View Plastic Surgery Clinic performs 3D-CT imaging for 3D analysis to precisely identify the bone structure and the position of the neural gland, effectively solve problems in the function of the chin and aesthetic issues, and minimize nerve damage through a safe surgery.

53D Morpheus virtual surgery simulation for predicting surgery results

Morpheus 3D scans the facial information, predicts the facial appearance after the surgery and displays a 3D image through cutting-edge 3D simulation.

It can precisely take images within less than 0.1mm error, scientifically evaluates the progress by 3D facial image comparison, and is able to effectively change the surgery plan if required.

This makes it possible for both the doctor and patient to share the surgery goal for a more precise surgery.
