Facial Anatomy and Its Importance in Health: A Practical Guide for Diagnosis, Prevention, and Treatment

A Guide to Applied Facial Anatomy

چکیده

ABSTRACT. The human face, a key indicator of overall health, is a complex and coordinated network of multilayered structures vital for function, identity, and communication. This review article examines facial anatomy from an integrated health perspective, demonstrating how a thorough understanding of its structures is critical for diagnosing diseases, preventing injury, and ensuring the safety of clinical procedures. It explores the superficial layers and the Superficial Musculoaponeurotic System (SMAS) as the first line of defense, the muscles of facial expression as tools for functional health, and the dual innervation system—motor (Facial Nerve, CN VII) and sensory (Trigeminal Nerve, CN V)—as a roadmap to neurological health. Key health implications such as facial palsy, trigeminal neuralgia, and skin infections are analyzed. Furthermore, critical health and safety considerations in medical and aesthetic procedures, including the vascular risks of filler injections and the significance of the "danger triangle," are highlighted. A comprehensive understanding of these relationships is essential for healthcare professionals to provide accurate diagnoses, effective treatments, and preventive care.
