Minimally invasive neurosurgery using CRW-3 stereotaxy

The Cosman-Roberts-Wells (CRW-3) scanner independent stereotactic system is a recent arc-radius design developed from the Brown-Roberts-Wells system. The results of 74 supratentorial non-basal tumor suspect cases treated with this second generation computed tomography (CT) guided stereotactic apparatus are presented. Using a simple stereotactic target classification coupled with biopsy, trephine or mini-craniotomy, it has been possible to biopsy, excise and develop new strategies using microneurosurgical techniques with extremely low morbidity.
