Abstract：
Purpose: To compare the efficacy of the vertical lid split (VLS) to the standard lateral canthotomy and cantholysis (LC/C) for orbital compartment syndrome (OCS) in the cadaveric model.Methods: Simulated OCS was achieved in seven fresh frozen cadaveric orbits. Orbital pressure (OP) was monitored in one control orbit and six interventional orbits. Initial OP was recorded before three right orbits underwent lateral canthotomy with superior and inferior cantholysis, and three left orbits underwent vertical lid split of the upper and lower eyelids. In all 7 orbits, OP was recorded for a total of 16 min. The main outcome measure was the amount of OP reduction at timed intervals.Results: Beginning OP in the control orbit was 109 mmHg, and average initial OP of the LC/C and VLS orbits were 90 and 103 mmHg, respectively. The control orbit maintained high OP without intervention. One minute after LC/C, OP decreased an average of 58.7 mmHg (65.2%; range 48-65 mmHg). One minute following VLS, OP decreased an average of 63 mmHg (61.0%; range 39-102 mmHg). At 16 min, OP reduction in the LC/C orbits averaged 65.3 mmHg (72.6%; range 56-71 mmHg), and OP reduction in the VLS orbits averaged 78 mmHg (75.5%; range 54-121 mmHg). Both interventions produced a comparable reduction in OP.Conclusions: Vertical lid split was found to be as effective as LC/C in reducing OP. The technical simplicity of the VLS lends itself well to utilization by physicians who are unfamiliar with eyelid surgery.
摘要：
目的：比较尸体模型中眶室综合征（OCS）的垂直眼睑劈开（VLS）与标准的外侧角切开术和角溶解（LC/C）的疗效。方法：在七个新鲜冷冻尸体眼眶中进行模拟OCS。在一个控制轨道和六个介入轨道上监测轨道压力（OP）。在三个右眼眶进行上、下角裂的侧角切开术之前记录初始OP。左三个轨道经历了上下眼睑的垂直眼睑分裂。在所有7个轨道中，记录OP总共16分钟。主要结果测量是在一定时间间隔内的OP减少量。结果：控制轨道开始OP为109mmHg，LC/C和VLS轨道的平均初始OP分别为90和103mmHg，分别。控制轨道在没有干预的情况下保持高OP。LC/C后一分钟，OP平均降低58.7mmHg（65.2％；范围48-65mmHg）。VLS后一分钟，OP平均降低了63mmHg（61.0％；范围39-102mmHg）。16分钟时，LC/C轨道的OP平均减少65.3mmHg（72.6％；范围56-71mmHg），VLS轨道的OP平均减少78mmHg（75.5％；范围54-121mmHg）。两种干预措施都产生了相当的OP减少。结论：发现垂直盖分裂在减少OP方面与LC/C一样有效。VLS的技术简单性非常适合不熟悉眼睑手术的医生使用。
