The gland is pea-sized and sits within the sella turcica, an area of the skull near the back of the nose. (valleygammaknife.com)
The most of cephalometric analysis and studies of the skull depend on the sella point to make liner and angular measurements, like Downs analysis (1948) [ 3 ], where he was used the sella landmark to make Y-axis plane that extend from sella to Gonthon (S-Gn) as one of skeletal reference plane, which indicate the degree of downward, reward or forward position of chin in relation to upper face.

The tiny gland sits in the sella turcica, a structure within the sphenoid bone, a bone that connects the facial bones to the skull bones. (elizabethsandelmd.com)

Pituitary function is checked by measuring hormone levels in the blood to rule out hormone excess or deficiency. (msdmanuals.com)
I.V. administration of gonadotropin releasing hormone distinguishes pituitary and hypothalamic causes of gonadotropin deficiency. (doctorlib.info)

The pituitary gland is surrounded by bone (sphenoid bone), and it sits in a pouch called the sella turcica. (cancer.ca)
The pituitary gland is a small, bean-shaped organ that sits at the base of the brain, behind the bridge of the nose (Fig. 1 and 2). (mayfieldclinic.com)
The pituitary gland is a pea-sized endocrine gland that sits at the base of the brain. (medscape.com)
The pituitary gland is enveloped by dura and sits within the sella turcica of the sphenoid bone. (medscape.com)

2) secondary empty sella is associated with the removal or treatment of PITUITARY NEOPLASMS. (mcw.edu)

The most common pituitary tumor, a prolactinoma, causes an overproduction of the hormone that helps control sexual function. (mayfieldclinic.com)

A quantitative study of the human hypophysis cerebri, or pituitary body. (thejcdp.com)

Higher grades are termed complete/total empty sella and lower grades are termed partially / partial empty sella . (radiopaedia.org)
Poll: Do you have a partially empty sella on your brain MRI? (phoenixrising.me)

It is now thought that many of these patients have idiopathic intracranial hypertension and that the empty sella is actually secondary to elevated CSF pressures. (radiopaedia.org)
As has been alluded to above, it is difficult to pin down the epidemiology for empty sella without contamination by patients with idiopathic intracranial hypertension . (radiopaedia.org)
A common underlying pathology to cases of empty sella both with and without intracranial hypertension may be hemodynamically significant transverse sinus stenosis, which results in altered CSF absorption and expansion of CSF spaces 13 . (radiopaedia.org)

Directly above the pituitary gland is the optic chiasm, which is responsible for vision. (mayfieldclinic.com)
The optic chiasma (where the optic nerves cross) is located on top of the superior part of the pituitary gland. (capsulehealth.one)
Craniofacial developmental anomalies may result in cleft lip and palate, basal encephalocele, hypertelorism, and optic nerve hypoplasia, with varying degrees of pituitary dysplasia and aplasia. (pediagenosis.com)
