[Microsurgery, a 'small' surgical revolution in the medical history of the 20th century].

Microsurgery in the twentieth century enabled surgeons to operate on very fine structures, which was impossible before the advent of the microscope. Since 1860 loupe magnification was employed in rare cases. In 1921 Nylén from Sweden transformed an ordinary laboratory microscope into an operation microscope for ear interventions. The eye specialists were the second group of doctors who employed the microscope in the operating theatre during the years 40-50 of this century. Since 1953 Zeiss in Germany has produced highly professional operation microscopes. In the sixties experimental laboratory studies were taken up to develop microsurgical techniques, microinstruments and suture material. Both plastic and reconstructive surgeons and neurosurgeons continued to develop microsurgery and indeed transformed their disciplines a great deal. Microsurgery is here to stay and still experiments are going on with video-assisted systems in order to further miniaturize the instruments for magnification and to gain a more comfortable working position for the surgeon.
