ABSTRACT
This chapter covers some considerations specific to the management of arteriovenous malformations (AVMs) in the region of the sylvian fissure, including lesions within the fissure, the adjacent opercular temporal, frontal, and parietal regions, the insula, and the mesial (medial) temporal lobe. AVMs of the sylvian fissure proper and of the surrounding opercular regions will be referred to as sylvian AVMs, while AVMs of the mesial temporal lobe will be designated as such. General information and principles regarding AVMs will not be presented here unless our philosophy or techniques are sufficiently different from others described elsewhere in this volume.
