目的:探究组织梯度差原理在修复切开法重睑术后重睑过宽中的效果。方法:2019年7月至2020年7月，四川省人民医院整形外科对双侧重睑过宽并要求修复女性患者30例(60眼，年龄20~35岁，平均30岁)用切开法进行修复。组织梯度差具体表现为重睑线上下皮肤、眼轮匝肌等软组织的厚薄差、质地差、张力差。结果:满意度评估，60眼中57眼(95.0%)满意；有3眼(5.0%)不满意。其中2例患者因矫正后两侧重睑宽度不一致而实施第2次修复，修复后1例患者获得满意重睑形态，另1例实施了第3次修复后获得满意重睑形态。重睑形态评估，配对n t检验结果显示，术后6个月与术前相比重睑形态有明显改善，差异有统计学意义(n t＝15.86，n P<0.01)。n 结论:组织梯度差原理指导重睑过宽修复简单易行，效果佳，值得应用。“,”Objective:To explore the effect of the principle of tissue gradient difference in repairing the over wide eyelid fold after double eyelid operation by incision.Methods:From July 2019 to July 2020, we applied the principle of tissue gradient difference to 30 cases (a total of 60 eyes; age ranging 20-35 years with mean 30) of female patients with excessively wide eyelids after incision double eyelid surgery needing a repair. All cases were from the Plastic Surgery Department of Sichuan Provincial People＇s Hospital. The difference in tissue gradient was manifested as the difference in thickness, texture and tension of soft tissues such as the skin above and below the double eyelid line and the orbicularis oculi muscle.Results:Satisfactory evaluation results showed in a total of 30 patients with 60 eyes, 95.0% (n n=57) were satisfied, and 5.0% (n n=3) were dissatisfied. Two of the patients received the second repair due to the inconsistency of the double eyelid width after correction. One patient obtained satisfactory double eyelid morphology after the second repair, and the other patient obtained satisfactory double eyelid morphology after the third repair. Evaluation results of double eyelid morphology showed that it obeyed a normal distribution by analyzing the difference between preoperative and postoperative double eyelid morphology scores. The results of paired n t test showed that the double eyelid morphology was significantly improved 6 months after operation compared with preoperative, and the difference was statistically significant (n t=15.86, n P<0.01).n Conclusions:The principle of tissue gradient difference guides the repair of double eyelid width that is simple and easy, the effect is good, and it is worth applying.
