Facelift and masseter muscle?

Thank you for your question.  Yes, the massester muscle, which lies on each side of the jaw bone can be prominent and add some width to the face.  This can be cosmetically displeasing for some.  I do not advocate reduction of the masseter muscle surgically.  However, a neuromodulator injection such as Botox or Dysport is an excellent way to reduce the size of these muscles.  Be sure to consult with a board certified facial plastic or general plastic surgeon, who specializes in facial rejuvenation procedures.  I hope that this helps!-David Gilpin

No, it is not possible. But botox can be used to decrease the thickness of the muscle and improve the shape of  the face.
