ABSTRACT
Precise preoperative craniotomy planning and intra-operative lesion localization and orientation have always been paramount issue in neurosurgery. The most important issues are the capabilities of surgical navigation system in appreciation of anatomy to avoid critical structures, arteries and veins. Furthermor, surgical planning for precise craniotomy, localization of lesion, extent of tumor resection increase the confidence of surgeon. The brain lab system [vectorvision.3, Germany] was used for guidance to 30 intra cranial operations. They were 21 male and 9 female, the mean age was [47.1], the range of age group was from 21 year to 70 year. All patients with brain tumors were diagnosed and managed in the departments of neurosurgery at Maadi Armed Forces Hospital, Cairo and Assuit University Hospital Assuit during the period may 2010 to may 2012. This study has shown reduction of surgical time, decrease blood loss during operation, decrease length of 1CU stay. Histopathological diagnosis was meningioma in 12 patients [40.0%], glioblastoma multiform in 10 patients [33.3%], astrocytoma GH in 5 patients [16.7%] and pilocystic astrocvtoma 3 patients [10.0%]. The surgical navigation system is helpful in mrgical planning for precise craniotomy, localization and orientation of the lesion, extent of the surgery reduction of surgery time and decrease in the length of 1C U stay and hospital cost
