[摘 要]目的 探讨对鼻假体歪斜患者采用聚左旋乳酸修复的有效性及安全性。方法 选取2022年6月-2023年5月成都锦江安吉拉医疗美容医院收治的隆鼻术后出现鼻假体歪斜的60例患者为研究对象，采用随机数字表法分为对照组(n=30)和观察组(n=30)。对照组采用玻尿酸进行修复，观察组采用聚左旋乳酸进行修复，比较两组修复满意度、面部角度、并发症发生情况及修复效果维持情况。结果 两组治疗后修复满意度评分均优于治疗前，且观察组优于对照组(P<0.05)；观察组鼻小柱上唇角低于对照组(P<0.05)；两组鼻额角、鼻面角、鼻唇角和鼻尖突出度比较，差异无统计学意义(P>0.05)；两组并发症发生率比较，差异无统计学意义(P>0.05)；观察组修复效果维持良好率为100.00%，高于对照组的90.00%(P<0.05)。结论 聚左旋乳酸修复鼻假体歪斜的有效性及安全性确切，该方式能够有效矫治鼻歪斜缺陷情况，从而塑造良好的鼻部形态，修复效果维持情况较好，修复满意度较高，值得临床应用。
