Understanding the anatomy of facial muscles is essential for both surgical and non-surgical aesthetic procedures. Facial muscles are divided into distinct anatomical regions, including the forehead, periorbital (around the eyes), external nose, perioral (around the mouth), and chin. These muscles typically originate from the underlying bones and insert into the skin and subcutaneous tissues, enabling a wide range of facial expressions.

Functionally, facial muscles act as sphincters, dilators, and dynamic structures responsible for conveying emotion through expression. Among these, the perioral muscles are of particular importance and are discussed in detail. This group includes the lip elevators, depressors, and the orbicularis oris, which encircles the mouth and plays a central role in lip movement and articulation.

The orbicularis oris muscle is not an isolated structure; its formation and function are influenced by the coordinated action of surrounding mimetic (expression-related) muscles. Understanding these interconnections is vital for precise aesthetic interventions.

Motor innervation of the facial muscles is supplied by the facial nerve (cranial nerve VII). Damage or dysfunction of this nerve, such as in facial nerve palsy, results in muscle weakness and asymmetry of facial expressions.

Muscle overactivity, particularly in aesthetic concerns such as dynamic wrinkles or gummy smiles, can be effectively managed with non-surgical treatments like botulinum toxin (Botox) injections. Rubin's classification of smiles is a useful tool in assessing smile types and guides treatment strategies for conditions like excessive gingival display (gummy smile).

This comprehensive anatomical knowledge underpins the success and safety of both reconstructive and cosmetic facial procedures.
