platysma

Full Definition

The platysma is a broad, thin muscle extending from the chest and shoulder to the lower face and jaw. In plastic surgery, platysma plication or division is a key component of neck lifting procedures and lower facelifts. The muscle's contribution to neck bands and jowling makes it a critical structure in facial rejuvenation surgery. Understanding platysma anatomy is essential for achieving natural-looking results and avoiding complications such as asymmetry or overcorrection.
