BACKGROUND: Autologous fat grafting (AFG) has been widely used to treat @entity5043 ( @entity5043 ). However, objective and quantitative analyses in @entity1 with @entity5043 are complicated because of multidimensional @entity194 and fat absorption. This study aimed to introduce a new method to predict @entity942 of soft tissues and objectively evaluate the survival of grafted fat with 3-dimensional (3D) and mirror-image analysis (MIA). METHODS: Thirty-one @entity1 with @entity5043 were classified into 2 groups based on the location of the facial midsagittal plane (FMP), which was established through our proposed method using nasion (point a), anterior nasal spine (point b), and pogonion (point c). The included cases with centered FMP were treated using serial AFG and followed up for 12 to 15 months. Images were obtained preoperatively (pre-OP) and postoperatively at 2 time points (3 months and 12 months). Three-dimensional computed tomography (CT) was performed before the first surgery to locate the FMP and predict the @entity942 of soft tissues with MIA. Three months after the first surgery, 3D laser scanning was conducted to evaluate the volume of surviving fat. @entity1 characteristics, satisfaction, and soft tissue augmentation results were analyzed. RESULTS: Twenty-seven cases (9 @entity1 and 18 @entity1 ) with @entity5043 were included and treated using serial AFG (mean number of operation, 3.1 times). The mean age was 22.1 years. With 3D CT or 3D laser-scanning camera and MIA, we obtained the mean deficient volume of the affected area (30.48 mm) and the mean volume of the total fat injection (133.61 mm). The mean fat absorption ratio was 47.92%. The mean satisfaction score immediately obtained at first postoperative (score = 4.3) was higher than that at 3 months postoperatively (score = 4.1) and 12 months postoperatively (score = 4.0). No complications and donor-site morbidity were noted. CONCLUSION: The facial symmetry of @entity1 with centered FMP can be successfully restored using serial AFG alone. The combined 3D and MIA can be used to predict the @entity942 of soft tissues and objectively evaluate the survival of grafted fat.
