Abstract：
BACKGROUND: The correction of tear trough deformity poses a significant challenge in the context of facial rejuvenation. Our aim was to introduce a technique that corrects tear trough deformity during transconjunctival lower blepharoplasty using minced orbital fat grafts.
METHODS: The medical records of patients who underwent lower blepharoplasty from January 2019 to December 2021 were reviewed. The study included patients with various grades of tear trough deformity, who underwent lower blepharoplasty using minced orbital fat grafts and followed up for at least 6 months. Modified Barton\'s grading for tear trough depression, patient satisfaction, and postoperative complications were evaluated.
RESULTS: A total of ninety-eight patients, with a mean age of 48.07 ± 9.72 years, consisting of 93 (94.9%) females were included in the study. The average duration of follow-up was 7.2 months, ranging from 6 to 13 months. Tear trough depression significantly improved after the operation (preoperative tear trough depression grade mean (SD): 3.11 (0.60); postoperative tear trough depression grade mean (SD): 0.87 (0.66); P < 0.001). 78.5% of the participants reported their outcome as excellent or good, 20.4% reported as fair, and 1.0% (only one patient) reported as no improvement. None of the participants rated their outcome as worsening. No major complication was observed during the follow-up period.
CONCLUSIONS: Minced orbital fat grafting during transconjunctival lower eyelid blepharoplasty has good effectiveness for correcting tear trough deformity without the risk of major complications.

摘要：
背景：泪槽畸形的矫正在面部年轻化的背景下提出了重大挑战。我们的目的是引入一种技术，该技术可以使用切碎的眼眶脂肪移植物在经结膜下睑成形术期间纠正泪槽畸形。
方法：回顾了2019年1月至2021年12月接受下睑成形术的患者的病历。该研究包括患有各种级别泪槽畸形的患者，使用碎眶脂肪移植物进行下眼睑成形术，并随访至少6个月。改良的Barton\'s泪槽凹陷分级，患者满意度,并对术后并发症进行评估。
结果：共有98名患者，平均年龄48.07±9.72岁，研究包括93名(94.9%)女性。平均随访时间为7.2个月,6至13个月不等。术后泪槽凹陷显著改良(术前泪槽凹陷分级均值(SD)：3.11(0.60)；术后泪槽凹陷分级均值(SD)：0.87(0.66)；P<0.001)。78.5%的参与者报告他们的结果是优秀或良好，20.4%报告为公平，1.0%(只有一名患者)报告无改善。没有一个参与者认为他们的结果恶化。随访期间无重大并发症发生。
结论：在经结膜下睑眼睑成形术中进行眼眶脂肪碎裂移植对矫正泪槽畸形具有良好的效果，且无重大并发症的风险。
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.
