[The audioanalysator. A bridge between audiometry and psychoacoustics].

An analyser with a system of continous sweeping frequencies and a spectrum of strongly different control signals is described here. Including the active participation of the patient and his impaired hearing a much more accurate finding of symptoms is possible than with the standard methods of audiometry. The major factors mentioned include the continuous fine testing of the sounds heard in an unlimitated choice of frequencies ranging between 20 Hz.

[Operative tasks with regard to the cranial base in otorhinolaryngology. III].

The decisive influence of the os sphenoidale in its different parts on the malformations and diseases of the oto- and rhinobasis. Congenital epidermoid (so called cholesteatoma) and entodermal cyst of the os petrosum. Malformations of the middle ear.

This presentation carries two goals: 1. Not to consider one particular aspect of a specified disease as a topic but rather an area of topography to which in general only a serving function is ascribed. For the vast multitude of pathogenetic processes taking place in this region our total understanding is required.
