What is posterior clinoid process?
The anterior, middle and the posterior clinoid processes are located in the middle cranial fossa of the skull. The posterior boundary of the pituitary fossa is formed by the dorsum sellae, the supero-lateral angles of which are raised to form the posterior clinoid process.
What is posterior Clinoid?
Description. The posterior boundary of the superior surface of sphenoid bone is formed by a square-shaped plate of bone, the dorsum sellæ; ending at its superior angles in two tubercles, the posterior clinoid processes, the size and form of which vary considerably in different individuals.
Why is it called clinoid process?
Clinoid likely comes from the Greek root klinein or the Latin clinare, both meaning “sloped” as in “inclined.”
Where is the clinoid process?
Background: The anterior clinoid process (ACP) is located close to the optic nerve, internal carotid artery, ophthalmic artery, and can be easily injured in an ACP-related surgery.
What attaches to the posterior clinoid process?
The posterior clinoid processes deepen the sella turcica, and give attachment to the tentorium cerebelli.
Is the posterior clinoid process part of the sella turcica?
‘Sella turcica’ indicates the pituitary fossa on the upper surface of the sphenoid body, defined anteriorly by two anterior clinoid processes and posteriorly by two posterior clinoid processes, the former being parts of lesser wings of the sphenoid bone and the latter the posterior boundary of the sella turcica of the …
What attaches to anterior and posterior clinoid process?
Petroclinoid ligament It extends between the posterior clinoid process and anterior clinoid process and the petrosal part of the temporal bone of the skull.
What is the anterior Clinoid process?
The anterior clinoid process (ACP) is a bony structure on the superolateral aspect of the sphenoid sinus lying between the internal carotid artery and the optic nerve.
What is a Clinoid meningioma?
Clinoidal meningiomas (CM) are benign tumors arising from the meningeal covering of the anterior clinoid process (ACP). These tumors have been referred to by various other terms, such as medial or inner sphenoid wing meningiomas.
What is the posterior sella?
Anatomy. The sella turcica is a bony depression in the sphenoid bone. The sella is bordered laterally by the cavernous sinuses, superiorly by the diaphragma sellae (dural fold), anteroinferiorly by the sphenoid sinus, and posteriorly by the pontine cistern. The pituitary gland normally sits within the sella.
What is anterior Clinoid?
What attaches to anterior and posterior Clinoid process?
What attaches to the posterior Clinoid process?
What doctor treats empty sella syndrome?
Jefferson Health endocrinologists provide comprehensive care and expert evaluation, diagnosis and treatment of empty sella syndrome and other disorders involving the pituitary gland.
What happens if the pituitary gland is damaged?
Hypopituitarism is when you have a short supply (deficiency) of one or more of the pituitary hormones. These hormone deficiencies can affect any number of your body’s routine functions, such as growth, blood pressure or reproduction. Symptoms typically vary, based on which hormone or hormones you are missing.
Does meningioma shorten life?
Although high survival rates are reported for WHO grade I meningiomas, complications and long-term disability occur frequently, which decrease quality of life. Studies on functional outcome of meningioma in patients usually include few patients and/or a short period of follow-up.
Do meningiomas stop growing?
Although the majority of meningiomas are benign, these tumors can grow slowly until they are very large, if left undiscovered, and, in some locations, can be severely disabling and life-threatening. Other forms of meningioma may be more aggressive.
