Diaphragma sellae • Forms roof of sella turcica • covers the pituitary gland, except in its center, which transmits the pituitary stalk • thin, tenuous structure not an adequate barrier for protecting the suprasellar structures during transsphenoidal operation • deficiency of the diaphragma sellae assumed to be a precondition to formation of empty sella. Primary empty sella syndrome happens when part of the brain pushes down into the sella turcica and flattens the pituitary gland. The sella is a transverse depression crossing the midline at the superior surface of the sphenoid bone that contains the pituitary gland, or hypophysis.
