睑袋整复术后下睑退缩的矫正

Correction of lower eyelid retraction following lower eyelid blepharoplasty

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 (2 7只眼 )下睑退缩较重者 ,施行经眦眦固定术同时行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 (2 5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。结论 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。

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.
