ABSTRACT:
The Carotico-clinoid foramen is an inconstant structure which is formed by the union of the anterior and middle clinoid processes by a ligament known as the carotico-clinoid ligament (CCL) which may be ossified The present study is to know the prevalence of carotico-clinoid foramen in skulls of Aurangabad District. For the present study, dry unknown human skulls from Aurangabad district ,were collected in the Department of Anatomy, Government Medical College, Aurangabad. The carotico-clinoid foramen was studied in dry human skulls and was observed for various parameters like complete or incomplete, unilateral or bilateral. The data was analysed statistically with Chi square test. The presence of carotico-clinoid foramen was observed in 100 skulls and was found in 24 skull bones (24%). Complete bilateral carotico-clinoid foramen was found in 2 skulls (2%) and complete unilateral foramen was found in 2 skulls (2%), one on the right side and one on the left side. Incomplete bilateral carotico-clinoid foramen was found in 8 skulls (8%).Incomplete unilateral foramen was found in 8 skulls (8%), on right side, 7 skulls (7%) and left side, 1 skull (1%). Bilateral carotico-clinoid foramen, complete right side and incomplete left side was observed in 2 skulls (2%). Bilateral caritico-clinoid foramen, complete left side and incomplete right side was observed in 2 skulls (2%). Variations in the anterior clinoid process (ACP) other than ossification are rare. The ossified carotico-clinoid ligament (CCL) may have compressive effects on the internal carotid artery. Thus anatomical knowledge of anterior clinoid process (ACP) and the clinoid space is of utmost importance for a neurosurgeon approaching the internal carotid artery or other skull based surgery. Excision of the ACP may be required for many skull based surgical procedures and the presence of any anomalies such as ossified (CCL) may pose a problem for neurosurgeons.
