Methods of Fat Tissue Processing for Human Vocal Fold Injection: A Systematic Review.

Objectives: We analyzed different methods used to process autologous fat tissues for vocal fold injection (VFI). VFI is a safe procedure that preserves the folds' original elasticity and vibration properties and rarely triggers foreign-body reactions, but is often a temporary treatment due to fat reabsorption. To avoid it, selecting a technique that provides as many viable implantable adipocytes as possible is mandatory.
