説明

The emission cochlegram was investigated in 11 cases of surgically proven unilateral acoustic neuroma. Stimulus sounds were tone-bursts with the duration of 3ms at 5 frequencies between 1kHz and 4kHz. The results obtained were as follows;<br>1) The emission cochleograms showed similar configurations in the unaffected ears, but showed various configurations in the tumor-bearing ears.<br>2) The averaged emission cochleogram of the unaffected ears showed the high-tone abrupt loss type of configuration, while that of the tumor-bearing ears showed the high-tone gradual loss type due to the elevation of pseudothreshold between 1kHz and 2kHz.<br>3) The comparison between pure tone audiogram and emission cochleogram could enable to speculate the pathophysiology of hearing loss in each case of acoustic neuromas.<br>4) The pathophysiology of hearing loss might differ on the different cochlear partitions in some tumor-bearing ears.
