Reconstruction of the flaccid cheek and sagging, adynamic commissure can either utilize static or dynamic procedures. The facial nerve has five main branches, although the anatomy may vary somewhat from individual to individual. The branches are, from top to bottom: frontal (or temporal), zygomatic, buccal, marginal mandibular and cervical. Each of these branches provides input to a group of facial expression muscles. Recovery The muscle is then attached to the superficial muscular aponeurotic system and zygomatic periosteum along the vector of pull, applying resting tension onto the commissure and creating a normal-appearing nasolabial fold (Fig. An official website of the United States government.
