Abnormal perilymph pressure (P. P.) has not been considered as a possible cause of sensorineural hearing loss compared with endolymphatic hydrops. This may mainly be due to the fact 1) that a method to measure or estimate P. P. is not available, 2) that there are few cases with sensorineural hearing loss suggesting abnormal P. P.
However, considering that the membrane structure of the cochlea, and the cochlear function depends on electrolyte components in endo-and peri-lymph, it is possible to assume that the abnormal P. P. may cause sensorineural deafness. In this report, sensorineural hearing loss which may be caused by the abnormal P. P. was described and discussed.
