Vitreous fovea traction played some roles in the formation of idiopathic macula hole in its early stage, but the traction included anterior and tangential direction. 玻璃体黄斑牵拉力在裂孔形成早期阶段起一定作用,其作用方向可能包括前向和切线方向。
Conclusion: The imaging anatomy of ethmoidal roof, cribrum and understanding of the formation of olfactory fovea is the instructive significance for anterior skull base surgery. 结论:了解筛顶板及筛板的影像解剖及嗅凹的形成对减少前颅底外科手术并发症的发生具有十分重要的意义。
