筛骨迷路眶板
Lamina orbitalis labyrinthi ethmoidei
- 拉丁语近义词: Lamina papyracea

定义
筛骨迷路眶板,又称纸样板,是一块薄而脆弱的骨板,构成筛骨迷路的外侧壁,并参与构成眼眶(即眼窝)的内侧壁。该骨板在保护眼睛方面发挥着至关重要的作用,将眶腔与筛骨气房分隔开来;筛骨气房是筛骨内众多含气空间的统称。
眶板位于眼眶内侧壁的特定位置,与多块相邻骨骼相连接。其上方与额骨相接,下方与上颌骨及腭骨相接,前方与泪骨相接,后方与蝶骨相接。这些骨骼共同构成眼眶内侧壁的精细结构。由于眶板毗邻筛骨气房,在筛窦感染时极易受损。此类感染可能进一步引发眶蜂窝织炎等严重并发症。
