  • Electrocochleographical findings in low tone sensorineural deafness.

説明

The cases with low tone sensorineural deafness were studied using the transtympanic-electrode technique of electrocochleography.<br>The results obtained were as follows:<br>1) Low tone sensorineural deafness of sudden onset without vertigo:<br>All the cases showed high AP and -SP amplitude and satisfactory CM response. These findings resembled the electrocochleographic findings of type I of Ménière's disease suggesting of the relationship with endolymphatic hydrops. The hearing returned to normal range in a half of the cases but remained hardly changed in the other half. The difference between these two groups could not be clarified electrocochleographically.<br>2) Familial progressive deafness showed low tone sensorineural deafness:<br>This case showed a high threshold and a low amplitude of CM at low frequency, and showed cochlear hair cell damage at low frequency range.<br>3) Low tone sensorineural deafness due to retrolabyrinthine lesion:<br>This case showed a normal CM but a low AP amplitude, and lacked a rapid increase of AP amplitude with increasing click intensity in the intensity region of AP input-output functions.
