Analysis of Clinical Application Effect of Autologous Fat Granule Transplantation in Facial Depression Plastic Surgery

Objective: To explore the clinical application effect of autologous fat granule transplantation in facial depression plastic surgery. Methods: A total of 98 patients with facial depression admitted to the plastic surgery department of our hospital from January 2021 to December 2023 were selected and divided into observation group (49 cases) and control group (49 cases) according to the random number table method. The observation group was treated with autologous fat granule transplantation, while the control group was treated with hyaluronic acid filling. The total effective rate of treatment, incidence of postoperative complications, improvement indicators of facial morphology (depth of depression, symmetry), and effect maintenance rate after 6 months of follow-up were compared between the two groups. Results: The total effective rate of treatment in the observation group was 93.88% (46/49), which was significantly higher than that in the control group (79.59%, 39/49) (P < 0.05). The incidence of postoperative complications in the observation group was 6.12% (3/49), which was lower than that in the control group (20.41%, 10/49) (P < 0.05). One month after surgery, the depth of depression (1.23 ± 0.31 mm) and symmetry (1.02 ± 0.15 points) in the observation group were better than those in the control group (P < 0.05). After 6 months of follow-up, the effect maintenance rate in the observation group was 89.80% (44/49), which was significantly higher than that in the control group (67.35%, 33/49) (P < 0.05). Conclusion: Autologous fat granule transplantation for the treatment of facial depression can significantly improve facial morphology, enhance treatment effect and patient satisfaction, reduce the incidence of complications, and maintain a more durable effect. It is a clinically preferred facial depression plastic surgery solution.
