To quantify the surgical outcomes of transconjunctival fat repositioning technique, we study the lower periorbital area with magnetic resonance imaging (MRI) and three-dimensional (3D) surface imaging. The preoperative and postoperative images were analyzed. The T1-weighted MR images in the quasi-sagittal plane parallel to the long axis of the orbit and passing through the globe center were used to measure the transposed fat, and 3D comparison was performed to calculate the tear trough depth. Changes throughout the surgery and their relationships with clinical characteristics were statistically analyzed. A total of 11 patients who underwent surgery were included. The mean follow-up period was 10.1 months. MRI measurements showed that the fat area beneath the tear trough increased from 0 to 22.7 ± 6.7 mm after fat repositioning, whereas the fat area of the eyelid bag decreased from 46.3 ± 11.0 mm to 25.5 ± 14.0 mm. The 3D results revealed an increase in thickness by 1.2 ± 0.4 mm in the tear tough areas. Both MRI and 3D imaging provide options to objectively assess the fat-repositioning technique.
为了量化经结膜脂肪重置技术的手术效果，我们使用磁共振成像（MRI）和三维（3D）表面成像来研究下眶周区域。对术前和术后的图像进行了分析。使用与眼眶长轴平行且穿过眼球中心的准矢状面 T1 加权 MR 图像来测量移位的脂肪，并进行 3D 比较以计算泪槽深度。对整个手术过程中的变化及其与临床特征的关系进行了统计学分析。共纳入 11 例接受手术的患者。平均随访时间为 10.1 个月。MRI 测量显示，脂肪重新定位后泪槽下方的脂肪面积从 0 增加到 22.7±6.7mm，而眼袋的脂肪面积从 46.3±11.0mm 减少到 25.5±14.0mm。3D 结果显示泪槽区域的厚度增加了 1.2±0.4mm。MRI 和 3D 成像都提供了客观评估脂肪重置技术的选项。
