This study aims to evaluate three-dimensional stereophotogrammetry measured volume changes in the tear trough area after lower blepharoplasty with midface lift with or without orbital fat manipulation. Among patients undergoing midface lift surgery, volume change by three-dimensional photography in the tear trough region was compared between those having no orbital fat manipulation, fat transposition, or fat resection. This is a prospective study of 260 eyelids of 130 patients who underwent cosmetic midface surgery. All patients had an external skin muscle flap midface lift. During the procedure, medial inferior orbital fat was resected, repositioned to a preperiosteal dissection pocket, or not manipulated. Forty-six patients (35.4%) had no fat manipulation, 42 patients (32.3%) had fat preservation with repositioning to the preperiosteal pockets on the medial inferior orbital rim, and 42 patients (32.3%) had fat resection without repositioning. All patients had volume gain in tear trough volume. The amount was not statistically significantly different between fat treatment groups. Mean follow-up time was 12 months (range 6-20 months). Midface lifting improved tear trough volume irrespective of how fat was manipulated.
本研究旨在评估中面部提升联合或不联合眶隔脂肪处理的下睑成形术后泪槽区的三维体层摄影测量体积变化。 在接受中面部提升手术的患者中，比较了无眶隔脂肪处理、脂肪移位或脂肪切除患者的泪槽区三维摄影的体积变化。 这是一项对 130 名患者的 260 只眼睑进行的前瞻性研究，所有患者均接受了美容中面部手术。 所有患者均采用外肌皮瓣中面部提升术。 在手术过程中，切除内侧下眶隔脂肪，重新定位到骨膜下解剖袋内，或不进行处理。 46 例（35.4%）患者未进行脂肪处理，42 例（32.3%）患者将脂肪保留并重新定位到内侧下眶缘的骨膜下口袋中，42 例（32.3%）患者切除脂肪而不重新定位。 所有患者的泪槽体积均有容积增加。 脂肪处理组之间的差异无统计学意义。 平均随访时间为 12 个月（6-20 个月）。 中面部提升术改善了泪槽容积，而不论脂肪如何处理。
