THE RESULT of stapedectomy depends essentially on the prosthesis used and its application. In order that a maximum improvement in hearing be obtained it is important that the prosthesis is firmly secured to the long process of the incus and efficiently transmits incudal vibrations. Another factor of importance is that a proper contact be established between the end of the prosthesis and the membrane sealing the oval window. For these conditions to be fulfilled, the prosthesis must be a suitable length, have a reliable and effective mechanism connecting it to the processus longus, and be so designed as to fit into a narrow window niche. Naturally, the material should be nonirritating and well tolerated by the middle ear.
In addition, a stapedectomy prosthesis should have one other quality which is of first importance for the operator, ie, ease of application.
These factors were kept in view in devising the
