Changes of facial volume maintenance rate after single autologous fat grafted for repaired progressive facial hemiatrophy

Abstract

Objective To measure the change of facial volume maintenance rate after autologous fat grafted for repaired progressive facial hemiatrophy by using three-dimensional digital technology. Methods 3D scanner was used to acquire facial data in 10 patients with progressive facial hemiatrophy before operation; Mimics 17.0 software was used to reconstruce patients＇ facial 3D model and to calculate the volume of facial tissue defect; autologous fat was grafted to repair facial deformity. The facial volume maintenance rate was calculated in all the patients 3 months and 6 months after operation. Results We had performed facial 3D data acquisition and facial repaired with autologus fat grafted in 10 patients; patients＇ facial morphology was improved. The mean facial volume maintenance rate was (35.80±3.44)% in 3 months and (27.82±3.80)% 6 months after surgery. Conclusions The mean facial volume maintenance rate in postoperative 3 months is inferior to that in 6 months in single autologous fat grafted for repairing progressive facial hemiatrophy.
