The sylvian fissure is not a simple longitudinal cleft as its name implies. It crosses both the basal and lateral cerebral surface and has a superficial and a deep part. The superficial part is visible on the surface of the brain and the deep part, referred as sylvian cistern, is hidden below the basal surface. The superficial part has a stem and three rami. The deep part is hidden. A study was therefore proposed to study the morphometry of sylvian fissure. The present study was conducted on 58 right and left formalin fixed human cadaveric cerebral hemispheres (29 Brains) that were obtained from the Department of Anatomy, Gandhi Medical College, Bhopal. Different parameters were studied like stem of sylvian fissure on inferior surface and lateral surface, posterior ramus of sylvian fissure, anterior rami of sylvian fissure and many more. These were statistically analysed. The mean of length of sylvian fissure on lateral surface was greater on the left hemisphere (71.79 ± 6.46 on the right and 75.15 ± 5.84 on the left). The mean of posterior ramus of sylvian fissure was greater on the left hemisphere (52.66± 4 on the right and 54.56 ± 3.24 on the left). More results and observations are mentioned along with the article. The results of many previous researches correlate with result of our study. It is very important for all anatomists and neurosurgeons to know about the sylvian fissure morphometry
