Fat Transfer Techniques: The Effect of Harvest and Transfer Methods on Adipocyte Viability and Review of the Literature

Abstract

The variety of techniques used to collect, clean, and reinject fat do not damage the fat cells except for the collection of fat at -700 mmHg vacuum. External ultrasound, preoperatively, does not destroy fat cells but produces smaller bundles of fat. The ratchet gun does not result in increased fat cell loss. Preoperative massage causes 30% cell loss and deformation of 80% of the remaining cells.
