title: Pterional approach to the contralateral orbit.
abstract: Of a total of 80 operated intraorbital lesions, 2 were located in the posterior intraconal space, medial and inferior to the optic nerve. Because they were unfavorably located for standard surgical approaches, we operated via a contralateral pterional transsphenoidal-transethmoidal route. This technique provided excellent exposure and results in these two cases of intraorbital cavernous malformations. A brief description of the approach is presented.
