睑袋整复术后下睑退缩的矫正

目的：探讨矫正睑袋整复术后并发的下睑退缩的理想方法。方法：对5例（8只眼）下睑退缩较轻者，单纯施行经眦眦固定术缩紧外眦腱使下睑缘上移复位；对15例（27只眼）下睑退缩较重者，施行经眦紫固定术同时行Hamra释放弓状缘和保留眶脂肪的下睑成形术，以在缩紧外眦腱的同时松解下睑眶隔和眶脂肪层的瘢痕挛缩，悬吊眼轮匝肌及提升中面部皮肤补充下睑前层不足。结果：术后14例（25只眼）得到6－12个月的随访，除1例（1只眼）较重的下睑退缩矫正不全外，其余均获得满意效果。结果：①经眦眦固定术是矫正轻度下睑退缩简单而有效的方法；②施行经眦眦固定术同时行Hamra下睑成形术是矫正较重度下睑退缩的理想选择。

Correction of lower eyelid retraction following lower eyelid blepharoplasty

OBJECTIVE: To investigate the ideal methods for correction of lower eyelid retraction following lower eyelid blepharoplasty. METHODS: Transcanthal canthopexy was used in 5 patients (8 eyes) with mild lower eyelid retraction. Transcanthal canthopexy combined with Hamra's lower blepharoplasty was used in 15 patients (27 eyes) with severe lower lid retraction. RESULTS: 14 patients (25 eyes) were followed up for 6-12 months. Of them, 13 patients achieved satisfactory results; one patient had undercorrection of retraction. CONCLUSION: Transcanthal canthopexy is a simple and effective method for correction of mild lower eyelid retraction following lower eyelid blepharoplasty. Transcanthal canthopexy combining Hamra's lower blepharoplasty may be an ideal choice for correction of severe lower eyelid retraction.
