颞骨的常规解剖和组织学切片不能显示颞骨表面和深部结构的立体关系,为耳蜗植入(CI)手术,这些中耳和内耳在结构上立体关系的确定极为重要。为此,作者用计算机辅助对6个颞骨解剖标志进行三维测量。颞骨均为右侧,尸龄在5个月、14、15、17、18和59岁,无耳疾。标本作成30μm 组织切片,经矫正投影于纸上,扫描重要结构图像轮廓,并将圆窗(RW)、圆窗膜(RWM)、圆窗龛(RWN)、鼓阶、骨螺旋腔、耳蜗基底膜(BM)、面神经(FN)、鼓索神经(CTN)、鼓岬、砧骨和镫骨结构资料输入计算机建立三维图像;
The regular anatomical and histological sections of the temporal bone can not show the three-dimensional relationship between the surface of the temporal bone and the deep structure. For the purposes of cochlear implant (CI) surgery, it is very important to determine the structural relationship between the middle ear and the inner ear. To this end, the authors used computer-assisted three-dimensional measurements of six temporal bone anatomical landmarks. Temporal bone is the right side, corpse at 5 months, 14,15,17,18 and 59 years old, no ear disease. Specimens were sectioned into 30 μm sections and corrected for projection on paper. The outline of the image of the important structures was scanned and the images of round window (RW), round window film (RWN), circular window niche (RWN), scala tympani, (BM), facial nerve (FN), chordoma (CTN), promontory, incus and stapes structure data into the computer to create three-dimensional images;
