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 clinoid process?
The posterior border of small wing of sphenoid, smooth and rounded, is received into the lateral fissure of the brain; the medial end of this border forms the anterior clinoid process, which gives attachment to the tentorium cerebelli; it is sometimes joined to the middle clinoid process by a spicule of bone, and when …
Which process is part of the sphenoid bone?
The sphenoid bone is said to be ‘butterfly-shaped’. It consists of a body, paired greater wings and lesser wings, and two pterygoid processes.
What attaches to the posterior Clinoid process?
The posterior clinoid processes deepen the sella turcica, and give attachment to the tentorium cerebelli.

Is the anterior 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 is Clinoid process?
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. Blockage of the drainage of a paranasal sinus for any reason can result in accumulation of trapped secretions and result in a mucocele.
What is 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.
