An anatomical study of the relationships between the coronal suture and the sulci of the convexity of the frontal lobe was accomplished in seven cephalic segments. The pre-central and central sulci are, respectively, 26,5 mm and 40,5 mm behind the bregma and 15,0 mm and 35,5 mm behind the pterion. The use of the coronal suture as point of reference, and especially, its relationship with the sulci of the lateral surface of the frontal lobe, allows to determine the projection on the cranium of the superficial cerebral lesions with the purpose to delimit the surgical access and to guide the approach to the cerebral convexity.
