The technical equipment of oto-microsurgery has especially during the last 2 decades been developed in many respects. Zeiss' operation-microscope (1953) is a sign of this development; also, knives, chisels, drills, scissors, etc. have been specially constructed for oto-microsurgery.
In spite of all improvements the unsuccessful operations that now and then are being reported surely depend not only upon imperfections of the surgeon but also of the instruments. The fine instruments are constructed for use by the human hand directly. This is, however, not always steady enough, which can be fatal in subtle micro-operations.
To avoid these situations as much as possible Nylén, after discussion with Tiselius and others, has initiated a construction of an oto-micromanipulator. Together with Herberts, Tove, Erikson, and Södergren different types of micromanipulators have been examined, and we have found that a mechanical type has the greatest advantages, especially from the viewpoint of stability. Such an apparatus
