The sellar region is of extreme importance to neuro-ophthalmologists: the optic chiasm lies directly above the sella turcica and many pathological processes that arise in this region cause visual dysfunction. The sella turcica or "Turkish saddle" of sphenoid bone lies above and behind the sphenoid sinus. Anterolaterally on either side of the sella are the anterior clinoid processes, with the posterior limit being the dorsum sellae. The pituitary gland is contained within the sella and a sheet of dura called the diaphragma sellae frames the superior opening and connects the clinoid attachments of the tentorium cerebelli above the gland. The diaphragma sellae is perforated to allow the infundibular stalk of the pituitary gland to connect to the hypothalamus.
