Neuromodulator Finesse for Masseter Hypertrophy and Bruxism.

A particularly prominent mandibular angle or a hypertrophied masseter muscle can result in an excessively wide facial appearance, which some individuals may find less aesthetically pleasing. Although normally a benign condition and strictly an aesthetic concern, a hypertrophied masseter can also cause pain, bruxism, and headaches. Neuromodulator for masseter reduction and treatment of bruxism has become first-line treatment. In this article, the authors present the senior author's (R.J.R.) anatomic approach to neuromodulator injection of the masseter, with a corresponding video of the injection technique.
