Some people have complaints of a face that is “too round”, or a jawline that is too “full”. For complaints that are directed toward extra fullness in front of the ears, this may be due to the enlargement of the masseter muscle. The masseter muscle is one of the muscles that help you chew, and you can feel it when you place your fingers on your jawline and bite forcefully. This is the flexing of your masseter muscle. A large muscle here is also associated with temporomandibular joint (TMJ) pain or arthritis, which can be a result of grinding one’s teeth at night.
My treatment for this group of muscles is a neuromodulator (such as Botox, Dysport, Jeuveau, or Xeomin). Typical treatments are 30-40 Units. Treatment of this area has the effect of “slimming” the jawline by reducing the prominence of the masseter muscles. It can also have the added benefit of better sleep, which is especially felt in patients that grind their teeth at night.
Neuromodulator treatments in the office take 15 minutes (most of which is spent talking about the treatment and expectations), and the effects are seen as early as 2 days, and by 2 weeks, all of the effects have taken place. The duration of treatment typically ranges from 3-6 months, depending on the individual patient and dose used.
