Li Guilin, Department of Neurosurgery, Xuanwu Hospital, Capital Medical University We can excise the tumor in the saddle area through a bone window of about 2 cm in the arch of the eyebrow to achieve minimal trauma. The upper left picture shows the intraoperative bone window, and the upper right picture shows a 4-year-old craniopharyngioma with a good result using this procedure. The two images below show pre- and post-operative films of surgical resection of saddle-nodular meningioma. This surgical approach is particularly suitable for surgery in pediatric patients and in elderly people with other organ dysfunction.
