The authors present the results of neuronavigation as a help to open neurosurgery for the tumors of the third ventricle. From January, 1995 to August, 1999, six image-guided surgical procedures were performed to remove third ventricle lesions : 4 colloïd cysts, 1 ependymoma, and 1 craniopharyngioma. The operative approach was transcortical in 5 cases, and transcallosal in 1 case. The use of neuronavigation allows a decrease of the surgical trauma during the surgical approach. The procedure secures the neurosurgeon in the choice and execution of his pathway to the target. It becomes however less accurate after opening the ventricle, because of the brainshift induced by the loss of cerebrospinal fluid becomes important. Nevertheless, neuronavigation is useful in the surgery of the third ventricle, especially if it is used with neuroendoscopy.
作者介绍了神经导航辅助第三脑室肿瘤开颅手术的结果。1995年1月至1999年8月，共进行了6例影像引导下的手术以切除第三脑室病变：4例胶样囊肿、1例室管膜瘤和1例颅咽管瘤。手术入路5例为经皮质，1例为经胼胝体。神经导航的应用减少了手术入路过程中的手术创伤。该技术使神经外科医生在选择和实施到达靶点的路径时更加安全。然而，打开脑室后，由于脑脊液流失导致的脑移位变得明显，其准确性会降低。尽管如此，神经导航在第三脑室手术中仍然有用，特别是与神经内镜联合使用时。
