Corpus callosotomy was reported for the first time by Dandy in 1922 and developed by Van Wagenen and Herren in 1940, but only Wilson in 1975 started performing it with a microsurgical technique. Its indications have remained controversial for a long time, but during the last years new interest has been raised concerning callosotomy as a treatment for some kinds of generalized epilepsy or as route to the anterior ventricular system. The microsurgical anatomy of the corpus callosum has therefore regained interest. With this goal in mind, the authors studied some aspects of the microsurgical anatomy of the corpus callosum, namely its dimensions, variability and topography, as well as the transcallosal access to the deep interfrontal region and to the third ventricle. This study was carried out on 30 normal adult brains, obtained from routine autopsies, that were submitted to a special preparation procedure and dissected with microsurgical technique. The main aspects of the operating features, the measurements made and the variation in the different parameters are described. Some references are proposed respecting the extent of anterior partial and subtotal callosotomy.
胼胝体切开术于1922年由丹迪首次报道，并于1940年由范·瓦根宁和赫伦进一步发展，但直到1975年威尔逊才开始采用显微外科技术进行该手术。长期以来，其适应症一直存在争议，但在过去几年中，胼胝体切开术作为治疗某些类型的全身性癫痫或作为进入前脑室系统的途径引起了新的关注。因此，胼胝体的显微外科解剖学再次受到关注。出于这一目的，作者研究了胼胝体显微外科解剖学的一些方面，即其尺寸、变异性和局部解剖，以及经胼胝体进入额深部区域和第三脑室的途径。本研究对30个正常成人脑进行，这些脑取自常规尸检，经过特殊制备程序后，采用显微外科技术进行解剖。描述了手术特征的主要方面、测量结果以及不同参数的变化。针对前部部分和次全胼胝体切开术的范围提出了一些参考意见。
