Nuances in Superficial Musculoaponeurotic System Rhytidectomy.

Rhytidectomy techniques have evolved since the early 1900s. As the understanding of facial anatomy and the aging process expanded, the superficial musculoaponeurotic system (SMAS) became a focal point in developing longer-lasting, natural results. Further evolution led to various approaches in repositioning the SMAS layer, including subperiosteal, composite, and deep plane rhytidectomies. This article describes the nuances of SMAS rhytidectomy, the biplanar SMAS imbrication technique, and adjuvant procedures used. This biplanar SMAS technique has been refined over more than 25 years and has proved to be a reliable and safe technique that leads to high patient satisfaction with minimal complications.
