PRP联合自体脂肪颗粒修复颞区凹陷畸形的美学效果观察OA

Objective To observe the aesthetic effect of platelet-rich plasma(PRP)combined with autologous fat granule in the repair of temporal depression deformity.Methods From May 2023 to May 2024,82 patients with temporal concavity deformity treated at Xuzhou Renci Hospital were selected and divided into an observation group and a control group using a random number table method,with 41 cases in each group.The control group was treated with autologous fat granule transplantation,while the observation group was combined with PRP filling repair.The patients were followed up for one year after surgery.The fullness of temporal depression and the change rate of soft tissue thickness were compared between the two groups immediately after surgery and at 1 year after surgery,and the occurrence of postoperative liquefaction focus,secondary filling rate,incidence rates of complications and patient satisfaction rate were counted.Results Immediately after surgery,the change rate of soft tissue thickness in the observation group was significantly higher than that in the control group(P＜0.05).At 1 year after surgery,the fullness of temporal depression and satisfaction rates of shape,fullness,color,smoothness and symmetry in the observation group were higher than those in the control group(P＜0.05),and the change rate of soft tissue thickness,incidence rate of liquefaction focus and secondary filling rate were significantly lower than those in control group(P＜0.05).There were no statistical differences in the incidence rates of complications between groups(P＞0.05).Conclusion PRP combined with autologous fat granule filling has an exact aesthetic effect in the repair of temporal depression deformity,and has low change rate of soft tissue thickness at 1 year after surgery,and it can effectively prevent the occurrence of postoperative liquefaction focus and avoid secondary filling,with high clinical safety and high patient satisfaction.
