颞骨内部结构复杂，组织成份较多，常规组织切片所示为二维图像，建立三维结构比较困难，所以在临床及教学中该部位为一难点。采用 ＣＴ及 ＭＲＩ进行的三维重建对精细的中内耳特别是膜性结构显示往往不太满意。作者采用颞骨火棉胶包埋连续片技术行中内耳及其毗邻结构的三维重 The internal structure of the temporal bone complex, more tissue components, conventional tissue sections shown as two-dimensional images, the establishment of three-dimensional structure is more difficult, so in clinical and teaching of the site as a difficult point. Three-dimensional reconstruction using CT and MRI is often not satisfactory for the fine middle ear, especially the membranous structure. The author uses the temporal bone fire cotton glue embedded continuous sheet technology in the inner ear and its adjacent structure of three-dimensional
