OBJECTIVES/HYPOTHESIS: To evaluate the effectiveness of free fat grafting in preventing Frey's syndrome (FS) and facial depression after parotidectomy compared with acellular dermis.
A prospective randomized trial was performed. Patients who underwent parotidectomy were randomly assigned to abdominal free fat or acellular dermis grafting groups. The occurrence of FS, the aesthetic outcome, economic results, and other complications were evaluated.
Both acellular dermis and free fat grafts were effective in preventing FS with an equal rate of postoperative complications. Patients undergoing free fat grafting had a significantly higher aesthetic score and lower cost than those undergoing acellular dermis grafting.
Free fat grafting has equal risks but more advantages compared with acellular dermis. Free fat grafting is an effective, convenient, and inexpensive option for parotidectomy defect reconstruction.

目的/假设：与脱细胞真皮相比，评估游离脂肪移植在腮腺切除术后预防味觉出汗综合征（FS）和面部凹陷方面的有效性。
进行了一项前瞻性随机试验。接受腮腺切除术的患者被随机分配到腹部游离脂肪或脱细胞真皮移植组。评估FS的发生情况、美学效果、经济结果和其他并发症。
脱细胞真皮和游离脂肪移植在预防FS方面均有效，术后并发症发生率相同。接受游离脂肪移植的患者美学评分显著更高，成本低于接受脱细胞真皮移植的患者。
与脱细胞真皮相比，游离脂肪移植风险相同但优势更多。游离脂肪移植是腮腺切除术后缺损重建的一种有效、方便且廉价的选择。
