Can Botox be used to slim jaw despite having had jaw correcting surgery?

Botox can be used to decrease the size of the masseter muscle and slim the jawline near the angle of the mandible. This should still be effective, even in a person with a history of jaw surgery. As Dr. Shieh mentioned, bite issues are possible, but not common. 
Be sure to see an expert physician injector who specializes in facial aesthetic procedures.
All the best,

Botox and the other neuromodulators can help decrease the prominence of the lower face and jaw. It does so by decreasing muscle hypertrophy in the masseter muscle which lays on the jaw bone. The masseter can become large through grinding and chewing gum, as well as with certain ethnicity. It is a simple and effective treatment which has no downtime and is done in the office. Results may be appreciated after one month and require a couple of treatments. Previous jaw surgery should not have any effect on the injection technique though there could be scarring on the bone muscle attachment.

Hello and thank you for your question.  There should be no issue with being treated with Botox after your jaw surgery.  These metal plates were placed in the bone, underneath the muscles that would be injected with Botox. Botox is used to slim down the jaw by treating the large muscles called the massesters.  These muscles are injected with just enough Botox to relax the muscles and lower their strength.  When the muscle is not being used to its potential, it shrinks down over time.   Be sure to see an experienced injector. Best of luck!

Thank you for your question. You sound like an ideal candidate for the laser-assisted weekend necklift because it is minimally invasive and can create a more contoured neck and jawline with a recovery as short as one weekend. Always work with a board certified facial plastic surgeon.
Best wishes,

Botox can be injected into the masseter muscles to slim the “jawline“ and narrow the lower face.  Due to the fact that it slims the lower face and jawline by atrophying the masseter muscles, having bony corrective jaw surgery is not a contraindication to this procedure.  I would make sure that you seek out a consultation with a board certified surgeon who is an expert on that anatomy.

Yes, you can have Botox after a jaw surgery and it can slim the masseter. Botox results resolve in 3-4 months. I recommend getting a consultation with a cosmetic dermatologist. Hope this helps.

Please check with the surgeon who did your jaw surgery and placed your metal plates to approve any future cosmetic treatments in that area. 

Botox can offer some degree of slimming effect only if there is hypertrophy of the mastication muscles especially the masseter. It is recommended that you follow with your surgeon for evaluation.

Great questionNo, there should be no problem using Botox that long after jaw surgery.  I perform both procedures (sometimes in the same patient) and have never had any issues.  The jaw surgery is well healed after a few months.  The small plates are  on the bone, and sit deeper than where the Botox is injected.   Botox is injected into the masseter muscle in the same areas, but not exactly.  Assuming your injector uses proper technique you should have no issueBest of luckDr Rodman
