Ptosis is a complication that can arise after blepharoplasty resulting in lid asymmetry. It should be recognized early and intervention directed at its underlying anatomical cause. Ptosis can be secondary to lid edema, hematoma, septal levator adhesions, septal suturing, supratarsal fixation, and levator complex injury. Injury to the levator complex can be rarefaction, dehiscence, or disinsertion. Evaluation of this condition involves assessment of the degree of ptosis and the amount of levator function. Severe ptosis with poor levator function requires reexploration and repair of the levator mechanism. Mild or moderate ptosis may resolve spontaneously and can be managed expectantly. Chronic cases (longer than 3 months) may need exploration, and the procedure used is guided by the amount of levator function present.
上睑下垂是睑成形术后可能出现的一种并发症，可导致眼睑不对称。应尽早识别，并针对其潜在的解剖学原因进行干预。上睑下垂可能继发于眼睑水肿、血肿、眶隔提上睑肌粘连、眶隔缝合、睑板上固定以及提上睑肌复合体损伤。提上睑肌复合体损伤可为肌纤维稀疏、裂开或断离。对这种情况的评估包括对上睑下垂程度和提上睑肌功能的评估。提上睑肌功能差的重度上睑下垂需要再次探查并修复提上睑肌机制。轻度或中度上睑下垂可能会自行缓解，可以进行观察处理。慢性病例（超过3个月）可能需要探查，所采用的手术方法取决于提上睑肌功能的情况。
