Background The atomic bombings of 1945 produced an unprecedented combination of thermal burns, radiation injury, and traumatic wounds. Survivors frequently developed extensive scarring, contractures, and unusually aggressive keloids—conditions that helped shape early approaches to reconstructive surgery and long-term scar management. Methods: A historical narrative review was undertaken using first-hand medical accounts from Hiroshima and early post-war reconstructive initiatives, alongside later analyses documenting the evolution of surgical care for atomic bomb survivors. Results: Early clinicians in Hiroshima described distinctive two-pattern burn distributions and a substantial burden of hypertrophic scarring. Block and Tsuzuki’s survey of 1950 identified keloids in nearly half of examined survivors, emphasising the reconstructive difficulty and high recurrence rates characteristic of radiation-associated scarring. In 1947, the establishment of the Atomic Bomb Casualty Commission (ABCC) provided systematic long-term follow-up of injuries, influencing surgical risk evaluation and survivorship protocols. A pivotal historical moment occurred in 1955 with the “Hiroshima Maidens” program, which brought 25 young women with severe facial burns and contractures to the United States for staged reconstructive operations. This initiative advanced international collaboration, refined techniques in grafting and flap reconstruction, and reframed reconstructive surgery as a discipline centred on function, dignity, and psychosocial recovery. Conclusion: The reconstructive challenges observed in post-atomic Hiroshima contributed to foundational developments in plastic surgery, particularly scar biology, burns reconstruction, and global surgical cooperation. The legacy continues to inform contemporary approaches to complex scarring and humanitarian reconstructive care.
