Background Congenital ptosis not only results in an asymmetric facial appearance but can lead to permanent visual disturbances if not addressed at an appropriate time. Crawford used fascia lata for suspension of the eyelid to frontalis muscle, which remains a standard procedure for congenital ptosis correction to date, with an acceptable recurrence rate due to graft slippage. There are many modifications in this technique to reduce this complication; hence, in this study, we share our experience of a modification to improve the outcomes. Methodology This retrospective study was conducted at a private tertiary care hospital in Karachi for 10 years. In total, 26 patients fulfilled our inclusion criteria. All patients underwent a modified Crawford's procedure under general anesthesia. Results In this study, the male-to-female ratio was 1:1.5. In total, 17 (65%) patients had unilateral ptosis. The mean age of presentation was 7 ± 3 years. All of our patients had poor levator function (<5 mm excursion) with a mean of 3 mm and mean grade of ptosis of 4 ± 1.6 mm. The mean preoperative marginal reflex distance (MRD) was +1.8 ± 0.6 mm. In this study, the patients had a mean postoperative MRD of 4.2 ± 0.7 mm at the four-week follow-up. Conclusions Although Crawford's procedure gives promising results for ptosis correction, suturing the fascial sling to the tarsal plate ensures good anchorage and prevents relapse.
先天性上睑下垂不仅会导致面部外观不对称,而且如果不及时治疗,可能会导致永久性视力障碍。克劳福德(Crawford)使用阔筋膜将眼睑悬吊于额肌,该方法至今仍是先天性上睑下垂矫正的标准术式,因移植片滑动导致的复发率尚可接受。该技术有许多改良方法以减少这种并发症;因此,在本研究中,我们分享一种改良方法以改善治疗效果的经验。
本回顾性研究在卡拉奇一家私立三级护理医院进行了10年。共有26例患者符合纳入标准。所有患者均在全身麻醉下接受改良的克劳福德手术。
在本研究中,男女比例为1:1.5。共有17例(65%)患者为单侧上睑下垂。就诊时的平均年龄为7±3岁。所有患者提上睑肌功能均较差(上睑移动度<5mm),平均为3mm,上睑下垂平均程度为4±1.6mm。术前平均边缘反射距离(MRD)为+1.8±0.6mm。在本研究中,患者在四周随访时术后平均MRD为4.2±0.7mm。
尽管克劳福德手术在上睑下垂矫正方面取得了不错的效果,但将筋膜吊带缝合至睑板可确保良好的固定并防止复发。
