Preoperative radiological analysis with CT & MRI is inevitable in planning endonasal transsphenoid surgery to avoid complications because of the high variability concerned with sphenoid anatomy.
Anatomical variations of sphenoid sinus esp. degree of [[pneumatization]], sellar configuration, [[septation]] pattern, inter carotid distance were evaluated. Results were significant and in concordance with other similar studies. Most frequently encountered pneumatization was sellar type and least was conchal type [[Sphenoid sinus]] [[pneumatization]] is directly linked to safe access to sella. Presence of septae within sinus need to be identified preoperatively to avoid damage and confusion intraoperatively
