Ocular and endocrine function in patients with pituitary tumors. Operative results following transnasal, transsphenoidal approach with marsupialization of the sella turcica.

Thirty-one patients with pituitary tumors underwent transphenoidal operation via a unilateral, trans-nasal technique preserving the nasal septum and marsupializing the sella turcica unless CSF leak could be demonstrated. These two modifications neither detracted from exposure nor predisposed to delayed complications and significantly facilitated the procedure.
