[Historical development of reconstructive surgery in head and neck oncology].

Reconstructive surgery is an important part of tumor surgery to the head and neck region. Large ablative tumor resections were already performed at the beginning of the 20th century, after it became possible to reduce intraoperative blood loss through improved surgical techniques or to compensate for it with transfusions. Another milestone was postoperative infection prophylaxis through the introduction of antibiotics. As one of the pioneers of radical tumor surgery, John Conley recognized the urgent need for reconstructive procedures. However, the beginnings were accompanied by postoperative functional impairments, which could only be improved with introduction of the deltopectoral and pectoralis major flaps. Another step was the introduction of microvascular grafts, which enabled better, situation-adapted reconstruction. Initially, however, the complication rates were rather high due to the inadequate technique of anastomosing small vessels as well as inadequate instruments. As a result, these methods were slow to gain acceptance. However, flap harvesting and microvascular anastomosis techniques continued to evolve, making microvascular tissue transplantation a reliable method that is now part of the standard repertoire of reconstructive surgery.
