Transsphenoidal chiasmapexy for correction of posthypophysectomy traction syndrome of optic chiasm. Case report.

Postoperative improvement occurred as a result of transsphenoidal chiasmapexy in a patient with posthypophysectomy visual loss. Traction injury of the optic chiasm may have been caused by a deficient diaphragma sellae and inadequate packing and repair of the sella floor. A cartilaginous seal is recommended.
