Microsurrgical Anatomy of the Basis Nuclei and White Fibers Associated With Three-Dimensional Images

The microsurgical approach to the basal ganglia (NB) was performed from the lateral surface of the cerebral hemispheres (HC) to the medial surface in order to preserve the related structures.Our objective was to perform microdissection of NB in three HC fixed in formalin under a surgical microscope to analyze the topographic anatomy of this region in relation to the white fibers of the brain (FB).The white fiber (FB) microdissection technique used was Klingler.During and after the microdissections, photographs were taken and three-dimensional (3D) images were produced, to better understand the depth of the anatomical structures.The anatomical details of the topographic arrangement of the NB with the FB were described.From the microdissection of the NB, in relation to the FB, the images generated in 3D provided a better understanding of the relationship between the superficial and deep structures of this region, contributing to the depth relationship of the structures studied.
