What is orthognathic surgery?

It is the medical specialisation that puts the bones of the face into the best position for chewing and to create a well proportioned, attractive face.

Orthognathic surgery is operating on the bones of the face

What does orthognathic surgery achieve?

Orthognathic surgery gives the patient greater facial harmony than before, by moving the upper jaw, cheekbones and jawbone/chin to create a more attractive face with more classical anteroposterior and vertical proportions.

How does orthognathic surgery work?

Dr Birbe makes small incisions in the bones (osteotomies) in order to move them and later set them in the right position with tiny plates and screws (osteosynthesis), working in three dimensions so the bones provide the right framework and proper skeletal support for the soft tissue.

What is Orthognathic surgery like at the Birbe Clinic?

  • After a joint evaluation, you will receive a firm, personalised quote and information on payment methods and financing.

  • We work closely with our team of orthodontists so that you don’t have to go to several centres.

  • When the time comes to plan the surgery, we will agree on a date that suits you and do the virtual 3-D planning to create the surgical splints.

  • Our nursing team will be with you in the clinic and help you put on the cryotherapy facemask to minimise swelling.
  • In general, you will be able to go home the day after the surgery.

  • You can begin your physical therapy sessions between two and three days after the surgery.

  • One week after surgery, you will begin postoperative orthodontics.

What results can we expect from the treatment?

Orthognathic surgery can bring about huge changes in both function and appearance, giving many facially discordant patients back their smile and confidence, as well as restoring chewing function in cases with malocclusion.

Conditions treated with orthognathic surgery

When a patient comes in with facial discordance, Dr Birbe analyses their face and smile to come up with the most appropriate surgical plan. Maxillofacial surgery, and specifically orthognathic surgery, is able to restore facial harmony and beauty to those with facial discordance and to highlight the natural beauty of normal patients by elevating aesthetic cannons of facial harmony (strong cheekbones, nose well positioned on the face, beautiful smile, etc.).

This may be due to a very long jawline, with the patient showing a lot of the upper gum when they smile (also known as “gummy smile” or “horsey smile”), to an excessively long chin (the patient is unable to put their lips together at rest) or to a large open bite (the patient can’t close their mouth because their teeth do not fit together).
This may be due to a very short jawline (the patient doesn’t show or shows very little of their upper teeth when smiling, which is a sign of ageing) or to a very short, recessed chin.
This may be due to a recessed chin or a cheekbone defect, or a combination of the two. Beautiful, balanced faces are somewhat convex in profile.
This may be due to a small jawline or an excessively small, recessed chin.

Cara corta

It looks like the individual has a very large jaw that sticks out, but in most cases it is the upper jaw that didn’t grow sufficiently, causing the middle third of the face to be sunken in and making it look prognathic, in which case we refer to mandibular prognathism.
