Topography of Sylvian Fissure and Central Sulcus as Neurosurgical Landmarks: an Anatomical Study Using Cadaveric Specimens in Iran

Although the wrinkles of the outermost layer of the brain vary among people and even between two right and left hemispheres, anatomical folds such as Sylvian fissure and central sulcus are more stable (the so-called anatomical landmarks) and their differences among individuals are not significant. Indeed, Sylvian fissure is the most recognizable part of the outer layer of the brain and thus Sylvian fissure and central sulcus are the main anatomical indices during brain surgery. Moreover, detailed knowledge of their size and distance from other anatomical indices such as the frontal pole, and detailed information about the distance of important locus from these markers are necessary, especially for specific surgeries such as frontal and temporal lobectomy.
