Gyral and Sulcal Microsurgical Anatomy

Abstract The complex set of sulci and gyri on the surface of the brain form a map with which neurosurgeons should be familiar when it comes to planning and carrying out their procedures, more particularly in the case of intrinsic brain lesions. Based on the general organization of the lobes and gyral convolutions of the brain, as defined by sulci and fissures, the pre- and intraoperative identification of the anatomical features of each patient is of critical importance. Knowledge of brain morphology is also essential to identify its different functional areas, given that both are closely associated. The correct interpretation of the excellent imaging techniques that are currently available is only possible through a solid grounding in anatomy and precise microsurgical principles. Only this way is it possible to achieve excellence in the indication, planning, and execution of the neurosurgical approach and microsurgical technique.
