When the cases of otosclerosis, chronic adhesive otitis media and dislocation of the incudo- sta pedial joint are examined using conventional Gelle's test, the results are always negative, and the test is of no use for the differential diagnosis of these diseases.Therefore, for the purpose of differential diagnosis, first, being confirmed that Gelle's test by bone conduction was negative, the qualitative test by air conduction was a pneumophon with applied to these cases.The following results were obtained:1.Otosclerosis:The application of positive or negative pressure to the external auditory canal generally reduces the loudness of air-conducted tones. 2.Otitis media chronica adhesiva:When a negative pressure is applied to the external auditory canal, air-conducted tone decreases in loudness like in the case of otosclerosis but the application of positive pressure to the auditory canal causes no decrease in the loudness of air-conducted tone. 3.Dislocation of the incudostapedial joint:When the negative pressure up to - 10mmHg is applied to external auditory canal air-conducted tone increases in loudness, but when the negative pressure up to -30_??_-40mmHg is applied, the air-conducted tone decreases in loudness.The application of positive pressure causes a decrease in the loudness of air-conducted tone just as in the case of otosclerosis. Summarizing the above, it seems that the differential diagnosis of those diseases negative to Gelle's test is made to some extent with the use of the qualitative test by air conduction with a pneumophon.
