火棉胶包埋法在海绵窦断层解剖研究中的应用

目的：建立一套以火棉胶包埋技术制备大体断层切片的方法并制作出海绵窦断层切片，为海绵窦的影像诊断学提供解剖学依据。方法：采用火棉胶包埋技术将标本制成连续切片，观察海绵窦在各个数面上的位置、形态、大小和内部结构。结果：火棉胶包埋法制备大体断层切片具有切片薄、无锯耗、无结构变形移位、切片标本易于观察和保存等优点。不同层面海绵窦的大小形态内部结构及毗邻关系明显不同，但同一层面海绵窦内部结构的位置关系基本恒定。冠状位切片观察海绵窦的结构优于横轴位。结论：火棉胶包埋技术是一种较好的大体断层标本制作技术。海绵窦断层解剖研究有助于影像诊断学对海绵窦病变的评价。

The use of the technique of celloidin embedding in the study of the cross - sectional anatomy of the cavernous sinus

Objective: To establish a method of making gross sectional slices by using the technique of celloidin embedding and provide anatomic evidences for diagnositic Imageology of the cavernous sinus(CS)by making slices of it.Methods:Twenty two cadeveric skulls of adults were chosen and made into continuous slices by using the technique of celloidin embedding.The location,shape,magnitude and structure of different slices of the CS were observed.Results: The advantages of the technique of celloidin embedding are as follows:thin slices,no consume of sawing,no replacement and distortion and the slices are easy to observe and reserve.The shape,magnitude,structures and relationship with arounding structures of different silces are apparently different.But the location of different structure in the CS in the same slices are consistent.The structures in CS are displayed better in coronal slices than in axial ones.Conlusion:The technique of celloidin embedding is a good technique of making gross sectional slices.The study of cross-sectional anatomy of the CS help to evaluate the diseases of it in diagnostic Imageology.
