MINIMALLY INVASIVE NEUROSURGERY USING CRW-3 STEREOTAXY

The Cosman-Roberts-Wells (CRW-3) scanner independent stereotactic syst em is a recent arc-radius design developed from the Brown-Roberts-Well s system. The results of 74 supratentorial non-basal tumor suspect cas es treated with this second generation computed tomography (CT) guided sterotactic apparatus are presented. Using a simple stereotactic targ et 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.
