[The Gellé-Test in Practice (author's transl)].

For diagnosis of otosclerosis the Gellé-test is useful although the measurement of impedance is more effective and correct. It's not imperative to pursue the test with the display of the pneumophone, but the simplest method by merely using Politzer-balloon into the external meatus is not acceptable. It ought to be arranged that a connecting tube is placed between the ballon and the closing-piece. The examination occurs with the b.c. receiver placed on the processus mastoideus. Frequency 500 cycles and intensity above the threshold 10-20 dB are recommended. Combining the Gellé-test with white noise produces interesting subjective phenomena.
