Incidence of carotico-clinoid foramen is an occasional presence in the human skull within the
middle cranial fossa. The presence may lead to compression of upturned course of internal
carotid artery,which may result in symptoms of compression of the artery like
headache,hypertension ,etc.
Aims & objectives: To study the incidence of carotico-clinoid foramen in Odisha population.
Materials and Methods: The present study is carried out in 41 dry human skull of odisha
population.All the skulls were observed to find the presence or absence of different variants of
carotico-clinoid foramen,whether complete or incomplete and unilateral or bilateral foramen.
Results:After thorough observation,it was found that,out of total 41 skull studied, 10 skull
showed the presence of different variants ofcarotico-clinoid foramen.Complete type was found in
5 skull out of which 1was seen on right side,1 on left side and 3 skull showed on both sides of
different skulls.Incomplete type was present in 5 more different skullwhere 2 on right side,2 on
left side and 1 skull showed on either side.
Conclusion:Detailed anatomical information regarding the occurrence of carotico-clinoid
foramen is of great help for various clinicians specially neurosurgeons for pre-operative
evaluation
