Why is it important?
Sylvian fissure is one of the most important landmarks of human cerebral hemisphere, with necessary surgical landmarks situated around its vicinity. Therefore, a research was designed to study the morphology of this anatomically and surgically significant fissure. The natural upward retraction of the apex of the pars triangularis commonly creates the largest opening in the superficial compartment of the sylvian fissure and provides an area on the convexity where the sylvian fissure is widest, and where it is often safest to begin opening the fissure. 58 formalin fixed cerebral hemispheres were taken and studied. 29/58 (50%) specimens exhibited U pattern while V and Y pattern was exhibited by 19/58 (32.76%) and 10/58 (17.24%) specimens respectively. most common pattern observed is U, followed by V & then Y. This study was then performed and carried further with comparing the difference in morphology of both sides.
