Orbicularis oris muscle. In human anatomy, the orbicularis oris muscle is a complex of muscles in the lips that encircles the mouth. Until recently, it was misinterpreted as a sphincter, or circular muscle, but it is actually composed of four independent quadrants that interlace and give only an appearance of circularity.
Lip Augmentation. Patients requesting lip augmentation come from all age groups. As we get older the lips age with the rest of the face resulting in atrophy of the lips. The lips thin out, tiny vertical lines appear, the graceful Cupid's bow of the upper lip begin to flatten, and the upper lip lengthens and hangs over the teeth.
