To summarize the etiology mechanism and treatment of iatrogenic blepharoptosis after double eyelid surgery in Asia.
To extensively review the literature related to iatrogenic blepharoptosis after double eyelid surgery, and to summarize and analyze the related anatomical mechanism, existing treatment options, and indications.
Iatrogenic blepharoptosis is a relatively common complication after double eyelid surgery, sometimes it is combined with other eyelid deformities such as sunken upper eyelid and wide double eyelid, which makes it difficult to repair. The etiology is mainly caused by improper adhesion of tissues and scars, improper removal of upper eyelid tissue, and injury of a link of levator muscle power system. Whether blepharoptosis occurs after double eyelid surgery by incision or suture, it should be repaired by incision. The principles of repair include surgical loosening of tissue adhesion, anatomical reduction, and repair of damaged tissues. The key is to use surrounding tissues or transplanted fat to prevent adhesion.
When repairing iatrogenic blepharoptosis clinically, appropriate surgical methods should be selected based on the causes and severity of the blepharoptosis, combined with treatment principles, in order to achieve better repair results.
总结亚洲地区双眼皮手术后医源性上睑下垂的病因机制及治疗方法。
广泛查阅与双眼皮手术后医源性上睑下垂相关的文献，并总结分析相关解剖学机制、现有的治疗方法及适应证。
医源性上睑下垂是双眼皮手术后较为常见的并发症，有时会合并上睑凹陷、双眼皮过宽等其他眼睑畸形，修复难度较大。病因主要是组织粘连及瘢痕不当、上睑组织去除不当以及提上睑肌动力系统某一环节受损。无论是切开法还是缝线法双眼皮手术后发生上睑下垂，均应采用切开法修复。修复原则包括手术松解组织粘连、解剖复位以及修复受损组织。关键是利用周围组织或移植脂肪防止粘连。
临床修复医源性上睑下垂时，应根据上睑下垂的病因及严重程度，结合治疗原则选择合适的手术方法，以获得更好的修复效果。
