Abstract：
Background The study determined to compare the clinical outcomes of traditional gold weight implantation for the correction of paralytic lagophthalmos with those of a newly designed model. Methods In this retrospective cohort study, we enrolled 30 patients (76% females; average age 60.8 ± 12 years) with facial palsy who underwent implantation of either the traditional pretarsal gold weight (PT group; n = 15) or a new supratarsal model (ST group; n = 15) from May 2014 to April 2019. The main outcome measures were the 12-month postoperative weight prominence, weight migration, improvement of lagophthalmos, upper eyelid contour, and upper eyelid ptosis. The secondary outcome was long-term (24 months) reoperative rate. Results The new model group had significantly better eyelid contour (risk ratio [RR] 3.16, 95% confidence interval [CI] 1.62-6.15, p = 0.001), less weight prominence (RR 1.74, 95% CI 1.13-2.70, p = 0.013), less weight migration (RR 1.31, 95% CI 1.12-1.54, p = 0.001), and less eyelid ptosis (RR 2.36, 95% CI 1.21-4.59, p = 0.011) than the traditional model group. Improvement of lagophthalmos was not statistically significant between the two groups (RR 1.44, 95% CI 0.72-2.91, p = 0.303). The 24-month reoperative rate was 53.3% in the PT group versus 13.3% in the ST group (RR 2.00, 95% CI 1.15-3.49, p = 0.015). Conclusion The newly designed supratarsal gold weight showed superior postoperative outcomes than the standard traditional model.
摘要：
背景这项研究决定比较传统的金重量植入与新设计的模型的临床结果。方法在这项回顾性队列研究中，2014年5月至2019年4月,我们纳入了30例面神经麻痹患者(76%为女性;平均年龄60.8±12岁),这些患者接受了传统的骨上金重量(PT组;n=15)或新的骨上模型(ST组;n=15)的植入.主要结局指标是术后12个月的体重突出，重量迁移，改善眩光，上眼睑轮廓，和上眼睑下垂。次要结果是长期（24个月）再次手术率。结果新模型组的眼睑轮廓明显更好（风险比[RR]3.16，95％置信区间[CI]1.62-6.15，p=0.001）。体重突出度较低(RR1.74，95%CI1.13-2.70，p=0.013)，体重迁移较少(RR1.31，95%CI1.12-1.54，p=0.001)，与传统模型组相比，眼睑下垂较少（RR2.36，95％CI1.21-4.59，p=0.011）。两组患者眼痛改善无统计学意义(RR1.44,95%CI0.72-2.91,p=0.303)。PT组24个月再手术率为53.3%，ST组为13.3%(RR2.00,95%CI1.15-3.49,p=0.015)。结论新设计的骨上金重量显示出优于标准传统模型的术后效果。
