The second fat graft has significantly better outcome than the first fat graft for Romberg syndrome: A study of three-dimensional volumetric analysis

Summary Background Patients with congenital or acquired deformities always need fat graft at least twice to remodel facial contour. The purpose of this study was to objectively evaluate the outcomes of the first and second fat grafts for Romberg syndrome by using three-dimensional (3D) volumetric analysis. Method A retrospective study was conducted using the medical records of 13 patients with Romberg disease who were treated with fat graft twice for facial filling. Patient and surgeon satisfactions were evaluated by comparing the preoperative and postoperative two-dimensional (2D) photographs. The preoperative and postoperative 3D images were analyzed with professional analysis software to calculate the volume discrepancy between them. Result According to the 2D photographs, both patients and the surgeon were more satisfied with the cosmetic results of the second fat graft. There was no significant statistical difference in the injection volumes between the two surgeries (p = 0.1); however, the survival rate of the second fat graft (75.1% ± 7.7%) was much higher than that of the first (43.3% ± 11.1%) with a significant difference (p
