Botox for Facial slimming
Botox does a good job in facial slimming (masseter injections) but it sounds like the zygomatic muscle was affected in the process. Unfortunately there is nothing you can do about this problem now but it will go away in approximately three months.
Botox for the Masseter (Jaw Slimming)
Thank you for the question. You hit the nail on the head: the zygomaticus muscles were affected by the Botox injections. This will resolve slowly over about 3 months. When injecting the masseter for jaw slimming, it is important to place the injections laterally and inferiorly (near the angle of the jaw). In addition, the injections are placed deeper than typical Botox injections. Please follow up with your provider to discuss your concerns.
Masseter Injection Problem
The masseter likely wasn't injected properly and the points were too medial and superior. With that said, any issues will return to normal in 2-3 months. Nothing will be permanent. I wish you the best of luck, Dr. Emer.
Smile muscles and botox
Yes, that was the answer I was going to say. MOre than likely it impacted your zygomaticus muscle and it should come back to normal when the Botox wears off.
Uneven smile after Botox
Since Botox is temporary, no permanent damage was done to your smile muscles. Over the next few weeks to months, you will notice strength returning to your smile spontaneously. This means no muscle retraining will be required...only time.
The good news is the dose was small so the unwanted effects...
won't last too long...most likely the injection targeted the wrong muscle...either the injection was too far superior or too close to the nose side of the cheek...not sure I accept the migration story...and it should take some time for the muscle to lose function...should not be right after the treatment...and then the muscle should work again within as little as 3-4 weeks to as long as 2-3 months...don't know what the squirting sensation was...no matter where the botox was injected you shouldn't feel anything squirting unless some dripped onto the surface of the skin which means even less made it to the muscle...
Botox injection for slimming masseter caused abnormal smile - Botox improperly injected is reason.
There are a couple muscles which could cause this problem, the zygomaticus or the risorius muscle. If injected too high, the zygomaticus will be affected, to anterior, the risorius will be affected. Either way, time will heal the problem and you have no worries about it being permanent. Steve Weiner, Facial Plastic Surgeon.
Change in smile
The usual reason for a squared off smile after masseter injection is that the injection was placed too high.
It should not happen when injected correctly near the masseter insertion.
It will wear off in about 3 months.
