Botulinum Toxin Treatment – Square Jaw/Broad Jaw Reduction

A square lower jaw is generally considered a very masculine trait. Widening of the lower third of the face can cause either a square appearance to the face as a whole or can distort the natural appearance of the angle between the chin and the neck.

A wide lower face can primarily be caused by enlargement of the mandible or masseter muscle.

What is the cause of a wide jaw?

The primary cause of an enlarged mandible is developmental or congenital. Behaviors such as repeated gum chewing, teeth clenching, teeth grinding, or bruxism can contribute to enlargement of the muscle.


There are several jaw reduction techniques available – both surgical and non-surgical. Ideally prior to selection of a treatment, the patient is examined to determine whether the cause is due to the bone, the masseter or both.

If the oversize jaw is primarily caused by enlargement of the enlarged muscle, patient can opt for convenient non-surgical method with simple injections.

When the enlarged muscle is injected, it weakens and exercises less, so it slowly becomes smaller over times. This treatment is a fast procedure that has very minimal discomfort. There is generally no downtime and improvement are gradual and natural looking. Patient will receive comments that their face looks slimmer without obvious signs of treatment done.

What to expect after treatment?

For the first 2 to 3 hours after treatment, take it easy and do not rub the treated area.  After that, you can return to your regular activities.
