Transnasal transsphenoidal approach to the sella

The transnasal transsphenoidal approach to the sella turcica has been refined and perfected through advances in medicine and technology. Originally performed for excision of pituitary adenomas, its present primary use is' pituitary ablation in hormonally dependent diseases. Our study of 55 patients who have undergone this procedure during the years 1970- 1975 demonstrates that this microscopic technique gives excellent exposure and visualization of intrasellar contents. Our method with several instrument modifications is discussed. It is technically an easy procedure with a minimum of morbidity and mortality.
