Endoscopic procedures in stereotactic neurosurgery.

A new prototype of an endoscope for stereotactic interventions is described. This endoscope is adapted to the Mundinger-Birg stereotactic system. Stereotactic endoscopic procedures are carried out for brain-tumour-biopsy as well as for evacuation of haematomas, brain-cysts and abscesses. Ventriculoscopy is performed on hydrocephalus and biopsy of ventricle-relating tumours. One-year experience with stereotactic endoscopy is reviewed.
