Experience in the surgical correction of congenital ptosis in 203 children operated on at The Hospital for Sick Children, Toronto, demonstrated that because of the different types and complicated nature of ptosis the choice of operation in each case is most important. Occasionally ptosis is associated with other anomalies such as blepharophimosis, epicanthus, and the jawwinking syndrome, which further complicate its repair. Although the results in complicated cases are not perfect, these children should be given the benefit of surgery, since almost all can be greatly improved. The best time for surgery is after three years of age but before the child starts school. If adequate levator action is present, shortening this muscle is the operation of choice. If levator function is poor, the lid is elevated by the frontalis muscle and fascia lata. Achievement of symmetry in the position of the lid and width of the palpebral fissure is the key to real success in ptosis surgery.
在多伦多病童医院为203名儿童实施先天性上睑下垂手术矫正的经验表明，由于上睑下垂的类型不同且性质复杂，因此每例手术方式的选择至关重要。上睑下垂偶尔会伴有其他异常情况，如睑裂狭小、内眦赘皮和下颌瞬目综合征，这使得修复手术更加复杂。尽管复杂病例的手术效果并不完美，但这些患儿仍应接受手术治疗，因为几乎所有患儿的情况都能得到极大改善。最佳手术时间是在患儿三岁之后、上学之前。如果提上睑肌功能良好，首选的手术方式是缩短该肌肉。如果提上睑肌功能较差，则通过额肌和阔筋膜来提升眼睑。实现眼睑位置和睑裂宽度的对称是上睑下垂手术真正成功的关键。
