This trial is being conducted to investigate the possible role of the patient's fat stem cells in grafts for inherited facial deformities. The trial is being conducted by the University of São Paulo School of Medicine and proposed to recruit 30 patients with craniofacial microsomia (an inherited defect of facial development). Participants will be randomly divided into two groups. One group will receive adipose derived regenerator cells, that were collected by liposuction, as well as a graft of fat during surgery (experimental group). The other group will only receive the fat graft (control group). Participants will be monitored for complications and for changes in graft survival.
