Chiasmapexy for the correction of traction on the optic nerves and chiasm associated with their descent into an empty sella turcica

Abstract

✓ A patient recovered full vision after evacuation of a chromaphobe adenoma and subsequent irradiation, but experienced delayed visual loss in the left eye associated with descent of the diaphragm of the sella and the optic nerves and chiasm into the tumor bed. More normal anatomical relationships were restored by inserting silicone sponge beneath the diaphragm of the sella. Vision improved rapidly thereafter and has been maintained for more than 3½ years.
