Abstract
Introduction: Eminentia arcuata is a crescent like raised projection observed at the middle cranial fossa on anterior surface of petrous part of the temporal bone. TheArcuate eminence, in anatomical term referred as the “eminentia arcuata” shows the site of the superior semi-circular canal of inner ear.
Materials and Methods: The research work was carried out in Department of Anatomy, Basic Medical Science, Saveetha Dental College. No sampling bias is used. The disadvantage of this study is that skulls from different geographical regions are not included. The parameters included are length and breadth of Eminentia arcuata on left lateral and right lateral side. The measurements are taken with a digital sliding vernier caliper.
Results: Length along with the breath of Eminentia arcuata on the left and right side was found to be nearly the same. This work was done to analyse the clinical implications and morphometric examination which found that length breath of Eminentia arcuata in most of the cadaveric skulls were nearly the same. In another research there was a controversy going on whether the Eminentia arcuata is formed by sulcus and gyri of the brain or by superior semi-circular canal.
Conclusion: On taking that research it is clear that the brain sulcus and gyri are just brain tissues which cannot cause Eminentia arcuata and its formation is by the superior semi-circular canal which is a bony structure of the inner ear.
