Analysis of the value of expanded polytetrafluoroethylene (e-PTFE) frontalis suspension applied to children with congenital ptosis.

Eighty clinical cases of children with congenital ptosis from October 2019 to October 2021 were randomly selected from our hospital. All children were divided into the observation group (n = 44) treated with e-PTFE frontalis suspension and the control group (n = 36) treated with frontalis flap suspension according to the treatment procedure. Comparison of eyelid condition [palpebral fissure height, margin reflex distance (MRD), eyelid closure time], ocular surface status [corneal fluorescein staining (CFS) score, tear film breakup time (TBUT), surgical eye lacrimal river height (LRH), sehirmer test I (STI)], frontal muscle strength of affected side, cosmetic results and complications in both groups at 1, 6 and 12 months postoperative follow-up.

At 1, 6 and 12 months after surgery, there was no significant difference in terms of palpebral fissure height and MRD between both groups (p > 0.05); After surgery, the eyelid closure time was shorter in the observation group than in the control group (p < 0.05). At 1, 6 and 12 months after surgery, the CFS scores were lower in the observation group than in the control group (p < 0.05); At 6 and 12 months after surgery, the TBUT was longer and the surgical eye LRH was higher in the observation group than in the control group (p < 0.05); At 1, 6, and 12 months after surgery, there was no significant difference in STI between both groups (p < 0.05). At 1, 6 and 12 months after surgery, the frontal muscle strength of affected side was higher in the observation group than in the control group (p < 0.05). At 1, 6, and 12 months after surgery, there was no significant difference in cosmetic results between both groups (p > 0.05). The overall complication rate in the observation group (6.82%) was lower than that in the control group (25.00%) (p < 0.05).

The surgical and cosmetic results of e-PTFE frontalis suspension and frontalis flap suspension applied to congenital ptosis are comparable, but the former has the advantage of faster postoperative recovery, better ocular surface status, less frontali muscle strength damage and fewer complications.

膨体聚四氟乙烯（e-PTFE）额肌悬吊术应用于先天性上睑下垂患儿的价值分析。

随机抽取我院2019年10月至2021年10月临床上80例先天性上睑下垂患儿。将所有儿童分为观察组（n = 44) 用 e-PTFE 额肌悬液治疗，对照组 (n = 36）根据治疗程序用额肌皮瓣悬吊治疗。眼睑状况比较[睑裂高度、边缘反射距离（MRD）、眼睑闭合时间]、眼表状态[角膜荧光素染色（CFS）评分、泪膜破裂时间（TBUT）、手术眼泪道高度（LRH）、 sehirmer test I (STI)]，术后 1、6、12 个月随访时两组患侧额肌力量、美容效果及并发症。

术后 1、6、12 个月，两组睑裂高度和 MRD 差异无统计学意义（p > 0.05); 术后观察组闭眼时间短于对照组（p < 0.05)。术后1、6、12个月，观察组CFS评分低于对照组（p < 0.05); 术后 6 个月和 12 个月，观察组 TBUT 较长，手术眼 LRH 高于对照组（p < 0.05); 术后 1、6 和 12 个月，两组的 STI 无显着差异（p < 0.05)。术后1、6、12个月，观察组患侧额肌力量高于对照组（p < 0.05)。术后 1、6 和 12 个月，两组的美容效果无显着差异（p > 0.05)。观察组总体并发症发生率（6.82%）低于对照组（25.00%）（p < 0.05)。

e-PTFE额肌悬吊术和额肌皮瓣悬吊术应用于先天性上睑下垂的手术和美容效果不相上下，但前者具有术后恢复快、眼表状态好、额肌肌力损伤少、并发症少等优点。
