目的 评价Medpor下睑插片作为下睑植入物治疗先天性及后天性下睑退缩的效果。设计 回顾性病例系列研 究。研究对象33例患者36眼,其中先天性下睑退缩4例6眼,后天性者29例30眼。方法 术前测量在第一眼位下睑相对角 膜下缘的位置及距下眶缘的位置。手术采用下睑袋皮肤切口,打开眶隔,视患者下睑退缩程度修剪Medpor下睑插片的形状及大 小,将植入物置于下睑板下缘及眶下缘骨缘之间。术后观察植入物是否移位或脱出。术后2周及3个月时测量下睑位置,观察其 变化情况。主要指标 第一眼位下睑位置。结果 对33例36眼行Medpor下睑插片植入者随访6-24个月,无植入物脱出及移 位。34眼在第一眼位下睑位于角膜缘或角膜下缘上0．5mm,2眼仍残存≥1mm的下睑退缩。结论 Medpor下睑插片作为植入物 可提供下睑长期的支撑,可达到良好的功能及美容效果。Medpor下睑插片可作为治疗下睑退缩的较理想植入物。
Objective To evaluate the effect of Medpor’s lower eyelid insert as a lower eyelid implant for congenital and acquired lower eyelid retraction. Design retrospective case series. Thirty-six patients (36 eyes) were enrolled in this study, including 4 cases of congenital lower eyelid retraction and 29 eyes of 30 cases of acquired diseases. Methods The position of the inferior eyelid at the first eyelid and the position of the inferior orbital rim were measured preoperatively. Surgical use of the lower eyelid pocket skin incision, orbital septum open, depending on the patient’s lower eyelid retraction Medpor lower eyelid insert shape and size, the implants placed in the lower edge of the lower tarsal and infraorbital margin between the bones. After surgery to observe whether the implant displacement or prolapse. The position of the lower eyelid was measured at 2 weeks and 3 months after operation, and the changes were observed. The main index of the first eyelid position. Results 33 patients (36 eyes) underwent Medpor lower eyelid implants were followed up for 6-24 months without implant prolapse and displacement. 34 eyes in the first eyelid eyelid or corneal margin of the corneal margin of 0.5mm, 2 eyes still remain ≥ 1mm lower eyelid retraction. Conclusion The Medpor lower eyelid insert, as an implant, provides long-term support for the lower eyelid and achieves good functional and cosmetic results. The Medpor Lower Eyelid Insert serves as a more ideal implant for the treatment of lower lid retraction.
