Jaw Augmentation

What is Jaw Augmentation Surgery?

Jaw Augmentation or mandibular augmentation is used to improve the appearance of jaws that may appear out of balance with other facial features. Jaw augmentation may also be used to correct structural jaw issues due to congenital deficiencies or facial trauma. The procedure is intended to restore visual balance to the face by making a prominent jaw less so, or by making so-called weak jaw appear more defined.

A large, prominent jaw is often identified as a more masculine characteristic, whereas a softer, less defined jaw is perceived as being more feminine. Performing jaw augmentation in conjunction with Facial Feminization Surgery or Facial Masculinization Surgery may help balance out the proportions of the face.

Who is a Candidate for Jaw Augmentation Surgery?

Anyone in good health who is unhappy with the appearance of their jaw or has structural issues from trauma or congenital deficiency is a candidate for jaw augmentation surgery.

Patients undergoing Facial Masculinization Surgery are ideal candidates for jaw augmentation, particularly when performed in combination with other facial procedures, as it will make the face appear more feminine or masculine.

Note, if you would like to reduce the appearance of a large or prominent jaw, you may be a good candidate for jaw tapering surgery, where the bone is shaved down with a rotary or burring tool. This procedure is often performed as part of Facial Feminization Surgery.

How is Jaw Augmentation Performed?

Jaw augmentation is performed by making an incision inside of the patient’s mouth and inserting implants. It is performed under general anaesthesia.

For jaw augmentation surgery, a manufactured implant is created to the desired jaw line shape. Once inserted, it is positioned flush against the existing jawbone and held in place with titanium screws. An identical implant is inserted on the other side. Closing sutures will dissolve on their own inside the mouth.

Depending on the desired outcome, this procedure is sometimes combined with Chin Augmentation to achieve an ideal balance of facial features.

What can I expect after surgery?

The most common side effect of this procedure is swelling, which typically peaks between 24 to 48 hours post-surgery. The significant swelling will subside within a few days, but there may be mild swelling that lasts several weeks or even months, so you may not see the final results of the jaw contour until a month or so after the procedure.

While healing, you may have limited ability to talk, smile, or fully move your mouth. Your doctor will discuss all dietary and oral hygiene guidelines with you to help promote optimal healing. You should avoid strenuous activity and exercise for the first two weeks.

Is there any scarring with Jaw Augmentation?

Since jaw augmentation operations are performed through incisions completely inside of the mouth, there are no external scars or visible evidence that an operation was performed.
