Surgical Clinical Integration era
Paul Tessier, a French craniofacial surgeon, advanced the practice by mapping three-dimensional surgical corridors and organ relationships in the 1960s–1970s, guiding safe dissection and organ-preserving approaches. Henri Rouvière, a prominent mid-20th-century anatomist, published topographic anatomy texts that linked precise tissue planes and vascular routes to operative planning. Frank H. Netter, as a leading medical illustrator, produced clear, topographically faithful images that translated descriptive anatomy into practical, image-guided references for surgery. Their work, within broader educational reforms and anatomy–pathology correlation, institutionalized anatomy as the primary guide for safe operative corridors, resections, and perioperative decision-making.
