[On the audiology of multiple sclerosis (author's transl)].
The paper reports about a female patient who developed an uncommon, unilateral, reversible hearing defect while suffering from multiple sclerosis. The tone audiogram showed a break in the hearing threshold curve down to values no longer measurable, progressing from the high to the low frequencies. There were all symptoms of a retrocochlear hearing defect. After about a month a restitutio ad integrum was achieved. The paper continues with discussions on the seat of the focus of demyelinisation with particular reference to the central part of the N. acusticus, whose myelin sheaths are formed by glia cells.
