3 cm in distal diameter is more suitable for the removal of the anterior and posterior clinoid processes, opening the back of the internal auditory canal and other deep bone removal operations through the keyhole approach.
The sella turcica in the sphenoid bone consists of a central hypophysial fossa and two pair of clinoid processes (anterior and posterior).
The occurrence of partially or completely ossified ligamentous connection between the anterior and middle clinoid processes forming the carotico-clinoid foramen was observed and noted.
The particular emphasis of the cranial work was on the following locations: where those cranial nerves cross the borders of tentorium cerebelli, as they pass through cavernous sinus, where the particularly vulnerable spot was, the fibro-osseous canal beneath the posterior clinoid processes, at sutura petrobasilaris, and where those nerves enter the orbit through fissure orbital is superior.
The caroticoclinoid foramen (foramen caroticoclinoideum) is formed when tops of the anterior and middle clinoid processes merge on the upper side of sphenoid bone.
The anterior clinoid processes of the lesser wing of the sphenoid are lateral to the tuberculum sella and project posteriorly.
Surgical removal of the anterior clinoid processes to expose of the structures of the cavernous sinus is more difficult when the interclinoid ligament is ossified, due to the established neural and vascular relationships (oculomotor, trochlear, abductor, ophthalmic and mandibular nerves, internal carotid artery, cavernous sinus and coronary sinus) (Ozdogmus et al.
The anterior, middle and the posterior clinoid processes are located in the middle cranial fossa of the skull.
In the lateral view, (1) the temperomandibular joints should be superimposed, and (2) the clinoid processes should be symmetrical.
The pneumatization of the sphenoid sinus can vary from total non-pneumatization to hyperpneumatization including clinoid processes, sphenoid wings and pterygoid plates.
