title: A Novel Technique of Supra Superficial Musculoaponeurotic System Hyaluronic Acid Injection for Lower Face Lifting.
abstract: BACKGROUND
  Various methods attempting to correct sagging of the lower face focus mainly on manipulation of the superficial musculoaponeurotic System. Each technique has its own limitation. The authors propose a relatively simple, conservative method utilizing hyaluronic acid injection just above the superficial musculoaponeurotic System.
  
  
  OBJECTIVE
  To address a novel hyaluronic injection technique to lift the lower face.
  
  
  METHODS
  Details of the injection techniques are described. The Position of the hyaluronic acid injected and the effect of hyaluronic acid on the superficial musculoaponeurotic System were confirmed by ultrasonography in one of the cases.
  
  
  RESULTS
  Sonogram images demonstrated the location of the injected hyaluronic acid and pressure effect of hyaluronic acid on the superficial musculoaponeurotic System, confirming the ability to manipulate the superficial musculoaponeurotic System by this injection technique. The lifting result of this Single injection technique was immediately visible and maintained for at least 26 weeks.
  
  
  CONCLUSIONS
  This is a less invasive, reproducible method that provides a sustained face lifting result. The authors propose the term "supraSMAS lift" for this novel injection technique.
