Is there a way to correct masseter muscle out of place after jaw angle implant removal?

Thank you very much for your question, it is important to be able to see images of your case to be able to orient it better, sometimes it requires technologies that allow repositioning the tissues, in this case we are talking about ultherapy, however if we talk directly about the masseter muscle, it can treat with botulinum toxin, but it is very important to have more information about your case and to be able to give you a closer answer,

There are two methods to correct the contour deformity of the masseter muscle retracting up over the bony jaw angle. There is muscle repositioning and a soft tissue implant to camouflage the muscle retraction. There are advantages and disadvantages to both approaches. One may be preferred over the other depending upon the extent of the muscle retraction.
