Morphometric Study Of Anterior Clinoid Process And Its Clinical Importance In Skulls Of South Indian Population

Abstract

The medial end of the lesser wing of sphenoid forms the anterior clinoid process which gives attachment to tentorium cerebelli, it is
sometimes joined with the middle clinoid process with a spicule of bone and forms carotidoclinoid foramen. This study is done to obtain
the knowledge of morphometry of the anterior clinoid process which is important for neurosurgeons in approaching the lesions of this
area.
The length of ACP, the width of ACP, and the distance of ACP from its tip to OS were measured from the right and left sides of 31
skulls( out of which 25 were males and 6 were females) using digital calipers.
In the case of the male’s length in left side is more than the right side with p<0.001, Where as width does not differ between the left
and right sides with p>0.05, Distance between ACP & OS was more significant than the right side with p-value p<0.001. presence of
carotid clinoid foramen was observed out of 11 carotido clinoid foramen( N=9 )were of incomplete form(most common), (N=1) contact
form and( N=1)was of complete form.
The knowledge of the morphology of ACP & CCF allows better surgical results and minimizes surgical morbidity.
