[Approach to tumors of the chiasm-sellar region with preservation of the olfactory tracts]. / Dostup k opukholiam khiazmal'no-selliarnoi oblasti s sokhraneniem oboniatel'nykh traktov.

ABSTRACT

Mobilization of the olfactory tract in mono- and bifrontal approach to the chiasmal-sellar region with preservation of its own vascular network down to the olfactory trigone on the side of the approach and for a distance of 20 mm from the other side creates adequate conditions for the operation. According to the EEG values, the degree of the operative trauma does not increase essentially and the prognosis of vision restoration is no worse. The olfactory function is restored immediately after surgery in most cases.
