Microscopic paraseptal sphenoidotomy approach for pituitary tumors.

Background: Dissection of mucosa from the nasal septum during a transsphenoidal approach may lead to significant morbidity. Endoscopic techniques that obviate this dissection and its complications have been successful for pituitary operations. These techniques, however, are generally not stereoscopic, can add significant costs, and in many instances require additional surgical personnel.
