摘要
目的:证明提上睑肌缩短术治疗上睑下垂,并术中适度过矫术后远期疗效更佳。
方法:本文对73 例共105 眼上睑下垂患者进行术后半年的随访。将患者分为过矫组和非过矫组。所有患者都行提上睑肌缩短术,过矫组术中将患侧上睑过矫约1～3mm,非过矫组不过矫。本文选择了过矫、矫正适度、矫正不足、暴露性角膜炎等指标分别在术后即刻,术后6 个月时进行临床效果评估。
结果:术后6 个月时过矫组矫正不足率远低于非过矫组,手术成功率也明显高于非过矫组。另外,随时间推移,矫正过度、睑裂闭合不全的程度逐渐降低。无一例并发暴露性角膜炎。
结论:对轻、中度先天性单纯性上睑下垂患者行提上睑肌缩短术时,术中应适度过矫1～3mm,其远期疗效明显优于术中不过矫的方法。只要术中及术后护理得当,术中适度过矫不会增加暴露性角膜炎的发病率。矫正过度和睑裂闭合不全较易恢复。
Objective To evaluate the result in patients undergoing levator muscle resection(shortening) and over correction in a sample of patients recruited from a field trial. Methods 73 patients with 105 ptosis upper lids were followed up for half a year, all of whom had taken the levator muscle resected(shortened). The sample were separated as an over-corrected group and a control group in which no over correction had been performed. We chose a couple of items(over correction, under correction etc.) to get the samples assessed. Result The under correction rate in over-corrected group was much lower than that in control group. And the over-corrected group got a better result than the other group by the time 6 months after the operation. Most of the complications were getting better 6 months after the sugery. Conclusion A better result we will get if we over corrected the upper lid for 1~3mm in the operation of blepharoptosis. It is not easy for the patients undergoing over-correted operation to get exposure keratitis. Over correction,under correction and difficulty in closing the eye is easy to recuperate.
