Abstract:
Objective:To investigate the clinical efficacy and safety of a modified injection technique for improving temporal concavity deformities.Methods:A prospective study was conducted on 157 female patients who underwent temporal concavity augmentation at the Department of Plastic Surgery, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences, from June 2019 to June 2022. The patients were aged from 32 to 48 (38.2±3.1) years. Granular fat was obtained through liposuction and purification. Using the midpoint of the frontotemporal line as the entry point, the granular fat tissue was injected evenly at multiple points under the skin and superficial temporal fascia. Additional granular fat was injected in the temporal edge area to ensure a smooth appearance. The visual analogue scale (VAS) was used to assess the patients' intraoperative pain levels. Follow-up visits were conducted for one year postoperatively to assess patient satisfaction with the improvement in temporal concavity, local pigmentation, and fine lines in the lateral orbital area based on preoperative and postoperative photographs. Complications, including swelling, ecchymosis, hematoma, fat embolism, infection, fat liquefaction, and subcutaneous induration, were recorded immediately after surgery and at the one-year follow-up.Results:All the 157 patients experienced mild swelling in the injection area postoperatively, which resolved within 3 to 6 days. Ecchymosis occurred in 15 patients and spontaneously resolved within 10 days. Eleven patients had asymmetry in the filled area, with 3 recovering after local massage and observation, and the remaining 8 undergoing a second fat grafting procedure. A total of 25 patients underwent more than two fat grafting procedures, including 4 who underwent three procedures. Mild local hematoma occurred in 3 patients postoperatively. The intraoperative pain VAS was (1.8±0.5) score. After treatment, the improvement scores for temporal concavity, local pigmentation, and fine lines in the lateral orbital area were (7.4±0.7), (6.8±0.7), and (7.9±0.7) scores, respectively. After one year of follow-up, no complications such as fat embolism, infection, fat liquefaction, or subcutaneous induration were observed in the 157 patients.Conclusion:The modified injection technique for improving temporal concavity deformities is safe and effective, with high patient satisfaction.
