The advancement of surgical techniques has enabled the neurosurgeon to undertake a continually more aggressive approach toward lesions within the fourth ventricle. Laboratory and clinical observations have enabled us to conclude that (1) exploration of the fourth ventricle is feasible without anatomical disruption of the vermis, (2) controlled ventilation during such explorations is physiologically most desirable, and (3) irrigation of neural structures must consider acid-base and ionic parameters in order to maintain physiologic stability.
