膨体聚四氟乙烯在泪沟矫正中的应用

The Application of the epolytetrafluoroethylene(ePTFE)in the Correction of the Tear Trough Deformity

目的:评价应用膨体聚四氟乙烯填充矫正泪沟的安全性与有效性。方法:2016年11月-2021年4月,针对无下睑手术史的泪沟就医者,采用经下睑缘切口在眶缘前下方骨膜上置入膨体的方法矫正泪沟,观察其临床效果及并发症发生情况。结果:本组共46例就医者,术后泪沟明显改善者37例、改善9例,就医者对手术效果满意者43例、一般者2例、不满意者1例,门诊随访3~50个月,泪沟矫正效果稳定,发生轻微睑球分离4例均在术后3个月内恢复正常,单侧假体移位1例,经手术修复后改善,无假体排异、感染、瘢痕增生、持续性下睑退缩等并发症。结论:应用膨体填充矫正泪沟是一种安全有效且效果持久的方法。

Objective To introduce a method using epolytetrafluoroethylene(ePTFE)to correct the tear trough deformity and evaluate the clinical effect of this treatment.Methods A retrospective study was conducted from November 2016 to April 2021.46 patients who showed obvious tear trough deformity and lower lid depression were treated with ePTFE to improve the appearance of the lower lid.Follow-up was performed for 3 to 50 months.The clinical effect and the complications was observed.Results 37 patients achieved complete correction and 9 patients achieved partial correction of the tear trough deformity,43 patients were satisfied with the surgical result while 1 patient was not.During the follow-up period,the effect of the surgery were lasting,4 cases of temporary eyelid ectropion occurred and relieved spontaneously within 3 months after operation,displacement was observed in 1 patient and corrected by reoperation with internal fixation.There were no complications such as rejection,inflammation,scar hypertrophy.Conclusion The method of using ePTFE for the correction of tear trough deformity was safe and effective which has the advantages of high security and permanent effect.It provides a new choice for the treatment of tear trough deformity.
