Abstract：
Even though the tear trough (TT) deformity is only 2 cm in length, it can give a worn, even haggard appearance on the face. The authors developed a novel approach and presented findings from the clinical effect.
Between February 2018 and January 2021, the medical records of patients treated with autologous fat injection for TT deformity were researched. The fat was placed under the orbicularis oculi muscle with a sharp cannula. During that period, the TT ligament was also released with the cannula. After the fat was injected entirely, we still needed to repeatedly puncture this ligament to release it until there was no puncture resistance. Improvement was evaluated by measuring patients\' and investigators\' global aesthetic improvement scale.
152 of 173 patients completed the follow-up plan and were enrolled in this study. The most common complications reported were temporary swelling and lumpiness. At 1 month, 3 months, 6 months, 12 months, and 24 months, the satisfaction rate of patient self-assessment was 93.4%, 89.5%, 86.8%, 84.3%, and 82.4%, respectively. The Investigator Global Aesthetic Improvement Scale showed 94.1% of patients\' improvement after one month, 83.6% after three months, 78.3% after six months, 75% after 12 months, and 71.8% after 24 months.
Fat injection based on TT ligament release to correct TT deformity is a novel, easy and effective treatment that deserves to be further used.

摘要：
背景：即使泪槽（TT）畸形的长度仅为2厘米，它可以给一个磨损，脸上甚至出现了憔悴的样子。作者开发了一种新方法，并介绍了临床效果的发现。
方法：在2018年2月至2021年1月之间，对接受自体脂肪注射治疗TT畸形的患者的病历进行了研究。用锋利的套管将脂肪置于眼轮匝肌下方。在此期间,TT韧带也用套管释放.脂肪完全注射后，我们仍然需要反复穿刺这个韧带来释放它，直到没有穿刺阻力。通过测量患者和研究者的整体美学改善量表来评估改善情况。
结果：173例患者中有152例完成了随访计划，并被纳入本研究。报告的最常见并发症是暂时性肿胀和肿块。在1个月，3个月,6个月,12个月,还有24个月,患者自评满意率为93.4%,89.5%,86.8%,84.3%,和82.4%，分别。研究者全球美学改善量表显示94.1%的患者在一个月后有所改善，三个月后83.6%，六个月后78.3%，12个月后的75%，24个月后为71.8%。
结论：基于TT韧带释放的脂肪注射纠正TT畸形是一种新颖的，简单有效的治疗方法，值得进一步使用。
方法：本期刊要求作者为每篇文章分配一定程度的证据。对于这些循证医学评级的完整描述，请参阅目录或在线作者说明www。springer.com/00266.
