Transsphenoidal decompression of the optic nerve and chiasm

Abstract

A review of recent experience with transsphenoidal surgery for lesions in and about the sella turcica establishes the value of this approach for the management of patients with visual loss. The lesions encountered consisted of pituitary adenoma in 45 cases, craniopharyngioma in 10 cases and miscellaneous tumors involving the sella in the remaining 7 cases. Sixty of the 62 patients in this series had quantitative determination of preoperative and postoperative visual status. After surgery, vision was improved in 81%, unchanged in 11% and worse in 5%. Two patients (3%) died during the immediate postoperative period before their visual status could be evaluated.
