presphenoid
the pituitary gland or hypophysis is often referred to as the "master gland" of the human body. part of the hypothalamic-pituitary axis, it controls most of the body's endocrine functions via the secretion of various hormones into the circulatory system. the pituitary gland is located below the brain in a depression (fossa) of the sphenoid bone known as the sella turcica. although anatomically and functionally connected to the brain, the pituitary gland sits outside the blood–brain barrier. it is separated from the subarachnoid space by the diaphragma sella, therefore the arachnoid mater and thus cerebral spinal fluid cannot enter the sella turcica.

the decision on whether to surgically decompress the pituitary gland is complex and mainly dependent on the severity of visual loss and visual field defects. if visual acuity is severely reduced, there are large or worsening visual field defects, or the level of consciousness falls consistently, professional guidelines recommend that surgery is performed. most commonly, operations on the pituitary gland are performed through transsphenoidal surgery. in this procedure, surgical instruments are passed through the nose towards the sphenoid bone, which is opened to give access to the cavity that contains the pituitary gland. surgery is most likely to improve vision if there was some remaining vision before surgery, and if surgery is undertaken within a week of the onset of symptoms.
