摘要目的:探讨眼轮匝肌下脂肪(SOOF)浅面眶隔脂肪释放、重置在下睑成形术中的应用效果。方法:回顾性分析2017年1月至2023年1月在清华大学附属北京清华长庚医院整形外科接受下睑成形术患者的临床资料。实施SOOF浅面眶隔脂肪释放重置下睑成形术：手术经皮肤入路，于眼轮匝肌与SOOF之间松解泪槽韧带和眼轮匝肌限制韧带；释放眶隔脂肪至眼轮匝肌与SOOF之间的间隙，外侧脂肪瓣固定于SOOF包膜，内侧脂肪瓣固定于提上唇肌浅面筋膜，重置眶隔，悬吊外眦。术后随访观察患者下睑形态及并发症情况。结果:共纳入58例患者，其中男8例，女50例；年龄(49.8±10.4)岁(32～70岁)；患者双侧下睑袋明显，并伴有泪槽畸形和(或)睑颊沟形成。术后有57例获得随访，时间为(29.1±16.9)个月(6～67个月)，所有患者下睑区域皮肤平坦，睑袋和泪沟获得明显改善，患者对手术效果均表示满意。2例于术后1周出现轻度下睑外翻，适度按摩于术后2周缓解；1例于术后1个月出现轻度下睑退缩，无不适主诉，未予特殊处置；1例出现球结膜出血，未予特殊处理自行恢复。结论:下睑成形术中于SOOF浅面对眶隔脂肪进行释放、重置，可有效地松解泪槽韧带和眼轮匝肌支持韧带，牢固地固定脂肪，能够降低手术操作难度，术后可获得平坦而紧致的下睑外观，且并发症少，患者满意度较高。

abstractsObjective:To evaluate the clinical effect of orbital fat releasing and repositioning through supra-suborbicularis oculi fat (SOOF) in lower eyelid blepharoplasty.Methods:The authors retrospectively analyzed the clinical data of patients who received lower eyelid blepharoplasty in the Department of Plastic Surgery, Beijing Tsinghua Changgung Hospital from January 2017 to January 2023. Lower eyelid blepharoplasty with orbital fat releasing and repositioning through supra-SOOF was performed. The tear trough ligament and orbicularis retaining ligament were released between the orbicularis oculi muscle and SOOF via skin approach. Orbital septal fat was released to this space, lateral fat flap was fixed to the SOOF capsule, medial fat flap was fixed to the superficial fascia of the levator labii superioris muscle, orbital septum was repositioned, and lateral canthus was suspended. After the operation, lower eyelid morphology and complications were evaluated.Results:A total of 58 patients were enrolled, including 8 males and 50 females with the age of (49.8 ± 10.4) years (32 to 70 years). All patients had obvious lower eyelid bags on both sides, combining the tear trough deformity and (or) palabromalar groove. Fifty-seven patients were followed up for (29.1 ± 16.9) months (6-67 months). All patients were satisfied with the operation. The appearance of lower eyelid was greatly improved, with elimination of fat prominence and tear trough deformity. Mild lower eyelid ectropion was observed two cases 1 week after the operation, and were relieved by moderate massage 2 weeks postoperatively. In one case, mild lower eyelid retraction was observed 1 month postoperatively, with no complaint of discomfort or further treatments. Bulbar conjunctival hemorrhage occurred in 1 case and recovered without further interventions.Conclusion:Lower eyelid blepharoplasty with orbital fat releasing and reposting through supra-SOOF can effectively release the tear trough ligament and the orbicularis retaining ligament, with stronger fat fixation and less surgical difficulty. After the operation, eyelid contour was flat and tight with fewer complications and higher patient satisfaction.
