The sphenoid bone is the unpaired bone in the cranium.It is present in the middle of the skull and it is an important surgical site. It is butterfly shaped with wings on either side that includes a greater wing and lesser wing of sphenoid. It has various attachments and foramina associated with it.The posterior part of greater wing projects like a triangular process called as sphenoidal spine which is the origin for sphenomandibular ligament.The aim is to study the morphometry of the location, shape, and variations of the spine of sphenoid and its clinical importance in different skulls of the south indian population.For this 30 adult dry human skulls of unknown sex of south indian origin were obtained from the Department of Anatomy, Saveetha Dental College, Chennai, Tamilnadu, India. All skulls were serially numbered from 1 to 30. In each skull, the shape of the spine of the sphenoid was observed and recorded. The distance of the spine from the tip of mastoid process and tip of the articular tubercle were measured on both the right and left sides of the skull using digital Vernier calipers. All data were tabulated and statistically analysed.The range of distance between the spine of sphenoid and the articular tubercle is found to be about 20.17-29.32mm(left) and 20.16-29.19mm(right) and the distance between the spine of the sphenoid and the mastoid process is found to be around 29.17-32.7mm(left) and 29.27-32.79mm(right). It is found that about 6.6% of spine is sharp, 46.6% is rounded in both left and right side, 26.6% is blunt on left side and 23.3% on the right side and about 20% on left and 23.3% on the right side were pointed type.The purpose of this study is to verify the morphometric variations in the location, shape of spine of sphenoid in different dry skulls of south indian and to find out its applications in various surgical procedures.
