Bilateral Carotico-clinoid foramen in Adult Human Skull and its surgical implication
Haldar A, Tirpude A, Tirpude P
The carotico-clinoid foramen was first described by Henle (1855), as an osseous bridge between the tip of the middle and anterior clinoid processes. The carotico-clinoid ligament connecting anterior and middle clinoid processes sometime get ossified forming the carotico-clinoid foramen which transmits one of the segment of internal carotid artery. The existence of a bony or osseous carotico-clinoid foramen may cause compression, tightening or stretching of the internal carotid artery, especially of the clinoidal segment. It may cause endocrinological problems affecting hypothalamus or hypophysis cerebri or neurological problems by affecting oculomotor or optic nerve, pituitary gland, which manifest as headache, behavioural changes, hormonal, visual, epileptic, craniofacial deviation and tooth anomalies, etc. The knowledge of the incidence and morphometry of the ossified carotico-clinoid foramen will help the neurosurgeons to plan a safe and effective surgery in the region of sphenoid bone in middle cranial fossa. Therefore, detailed anatomical knowledge of the carotico-clinoid foramen is of utmost importance, to increase the success of regional surgery. Thats why thorough anatomical knowledge is of great clinical help for neurosurgeons, neuro-physicians, endocrinologists, radiologists, anatomists and biological anthropologists.
