The "Dancing Chin"

I'd like to present a new term that patients, physicians, and plastic surgeons should get to know: the "Dancing chin."

The term "dancing chin" refers to an over-the-top movement of the three muscles in the chin (namely the mentalis, depressor labii inferior, and depressor annuli oris) and the primary neck muscle known as the platysma, which can occur both intentionally and involuntarily, such as in the case of a tic.
