Changes of facial volume maintenance rate after single autologous fat grafted for repaired progressive facial hemiatrophy / 中华医学美学美容杂志

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.
