“…A standard transsphenoidal approach is commonly used to treat these lesions, supported by maneuvers that facilitate the descent of the tumor into the sella (e.g., Valsalva maneuver, jugular vein compression, and lumbar infusion). Other treatment options for a significant suprasellar extension of a tumor include staged transsphenoidal removal (Mohr et al, 1990;Saito et al, 1995), with or without the use of the open sella method (Saito et al, 1995), a combined transsphenoidal and intracranial approach (Burian et al, 1970;Laws et al, 1977;Loyo et al, 1984), and a transcranial approach only. Recently, Mason et al (1997) described a transsphenoidal approach extended to the supradiaphragmatic intradural space to remove lesions at the level of the pituitary stalk.…”
