ABSTRACT

Pterional, trans-sylvian approach is a basic and most popular neurosurgical procedure used in surgical treatment of various vascular, tumor and other lesions located in and around the sellar and parasellar region. It has several benefits such as a shorter working distance, anatomical familiarity, lesser need for brain retraction with wide sylvian dissection, ability of extension with some modification. All anterior circulation aneurysm except pericallosal origin aneurysm and some aneurysm of posterior circulation can be approached with pterional, trans-sylvian method. The authors discribe the procedure of pterional trans-sylvian approach.
