ETV is a well established and successful method in contemporary neurosurgery. With growing experience there is a more efficient patient selection and further advances in technical know how. We evaluated retrospectively a consecutive group of 27 patients who were treated in our institution by stereotactic guided ETV between 1992 and 1996. When reviewing their postoperative imaging studies (MRI/CT) we could measure the position of the burr hole as port of entry for the rigid endoscope in 17 out of 23 finally selected patients. The median lateral position was 28 mm (mean 26.5 mm) from the midline and 8 mm (mean 6.5 mm) anterior of the coronal suture. We conclude that the optimal burr hole position should be 3 cm lateral to the midline and 1 cm anterior of the coronal suture, in the patients with normal anatomical findings.
内镜下第三脑室造瘘术（ETV）是当代神经外科一种成熟且成功的方法。随着经验的积累，患者选择更加高效，技术知识也有了进一步的进步。我们回顾性评估了1992年至1996年间在我们机构接受立体定向引导下ETV治疗的连续27例患者。在复查他们的术后影像学检查（MRI/CT）时，我们能够在最终选定的23例患者中的17例中测量作为硬质内镜入口的钻孔位置。钻孔的中位外侧位置距中线28毫米（平均26.5毫米），在冠状缝前方8毫米（平均6.5毫米）。我们得出结论，在解剖结构正常的患者中，最佳钻孔位置应在距中线3厘米外侧和冠状缝前方1厘米处。
