Essential Surgical Anatomy for Facelift

Abstract It is crucial for a facelift surgeon to have a comprehensive understanding of ageing-related changes on the volume, elasticity, and relative position of various facial tissues and layers. These changes lead to an alteration in the surface topography, contour, and ultimately shape of the face. The depressions and sagging of tissues created as a result of ageing then has a bearing on one's perceived age. This article describes the various layers of the face and neck affected by ageing. The fat compartments, superficial musculoaponeurotic system (SMAS), potential facial spaces, facial ligaments, and facial nerve are discussed in detail. Safe and effective execution of facelift requires a thorough understanding of the intricate relationship between the various layers of face and neck, in particular the path of facial nerve, as it negotiates between these layers. The emphasis of this article is on integrating this knowledge to generate practical tips for safe dissection, effective tissue movement, and repositioning during various type of facelift procedures.
