摘要 目的应用三维重建技术研究面神经乳突段神经纤维的空间配布规律。方法取5只新西兰大白兔面神经全段及周围颞骨、脱钙、石蜡包埋、连续切片后神经三色染色,观察拍照、经图形配准后,利用Mimics软件重建显示面神经纤维的空间构筑。结果兔面神经乳突段神经纤维聚集成簇,但周围无明显神经束膜;神经纤维之间相互交叉,重组,形成复杂的网络结构。结论利用计算机三维重建技术可显示面神经乳突段神经纤维的空间配布规律,为研究面神经显微解剖形态提供参考。 Objective To investigate the spatial configuration of the mastoid segment of facial nerve adopting the three dimensional(3D)reconstruction technique.Methods Five pairs of rabbit facial nerve and temporal bone were extracted and embedded in paraffin.After special trichrome stain,the serial sections were performed,observed and photoed under the microscope.And then,the images were imported to the Mimics software to reconstruct the 3D model to show the spatial configuration of facial nerve bundles.Results The facial nerve fibers assembled to fascicles without perineurium,and intertwined with each other to form a complex network structure.Conclusions The computer aided 3D reconstruction can show the spatial structure of facial nerve bundles and provide reference for the microanatomy.
