abstractsObjective:To explore the application effect of mid-facial autologous fat grafting with an intraoral approach in facial contour remodeling.Methods:A retrospective study was performed for 89 female patients aged (35±10) years who underwent mid-facial autologous fat grafting in the Department of Plastic Surgery, Easysculpt Medical Aesthetic Clinic from October 2019 to October 2022. The filling area was designed according to the patient's facial characteristics. According to the patient's wishes and the actual thickness of subcutaneous fat, the abdomen or thigh were selected as the fat collection area. Nerve block anesthesia with 0.5% lidocaine was performed at the corresponding site. The edge of the hairline was chosen to be the insertion point when filling the frontal, temporal, eyebrow arch, and zygomatic arch depression; An intraoral approach was used when filling the middle and lower parts of the face. The surgical effect and complications were recorded at 3 months after the operation, and the patient satisfaction was evaluated.Results:All the patients completed the operation smoothly. A total of 82 patients received a single injection, 5 patients received two times and 2 patients received three times. Fourteen patients had mild facial swelling after surgery, which subsided spontaneously in 1-2 weeks. None of the 89 patients had complications such as embolism, infection, hematoma, induration, cyst, fat liquefaction, pigmentation, dysesthesia or depression. At the 3-month follow-up, 67 patients were very satisfied with the postoperative results, 14 patients were satisfied, 6 patients were generally satisfied, and 2 patients were not satisfied. The overall satisfaction rate was 91.0% (81/89).Conclusion:The intraoral approach to middle face fat transplantation is safe and effective in facial contour remodeling.
