选择１２例小儿脑室内中线区肿瘤病例，立体定向经额入路全切除或选择性部分切除；其中侧脑室８例，第三脑室３例，左侧脑室跨室间孔１例，术后症状改善明显，并发症少，且无明显的神经心理学障碍，手术所致肿瘤周围正常组织损伤小，重点讨论立体定向经额入路与经中线切开胼胝体入路术后的神经病学与神经心理学障碍情况，认为在儿童发育阶段，由于大脑未发育完全，部分损伤胼胝体可致神经病学改变及神经心理学障碍，而应用立体定向经额入路可以避免 Select 12 cases of pediatric intraventricular midline tumor cases, stereotactic total frontal approach or partial resection; including 8 cases of lateral ventricle, third ventricle in 3 cases, 1 case of left ventricle interventricular septum, postoperative symptoms Improve obvious and less complications, and no obvious neuropsychological disorders, surgery caused by normal tissue damage around the tumor is small, focusing on stereotactic transcranial approach and by the midline incision of the corpus callosum postoperative neurology and neuropsychology Learning disabilities, that in the child development stage, due to the brain is not fully developed, part of the injury corpus callosum can cause neurological changes and neuropsychological disorders, and the use of stereotactic approach can be avoided
