[Technical considerations for the massive practice of hair transplantation].

Based upon his broad experience of over 2.000 transplant operations, the author notes the frequent patients refusals of multiple sessions and suggests adaptations of the Orentreich technique, to obtain a new modified single session operation allowing insertion of up to 250 to 300 hair plugs. After giving a detailed description of the technical modifications related to the anesthesia, hemostasis, biological integrity of the transplants, local blood supply and other problems, which had to be solved in order to obtain valid results within a record time, the author presents his final results.
