[Function of acoustic analyzer in multiple sclerosis in exacerbation].
Audiometric examination of 51 patients with aggravated multiple sclerosis included pure-tone threshold audiometry, assessment, of speech intensity function, of adaptation, masking, sound laterality, impedance tympanomanometry, perception of complicated speech, registration of short-latency acoustic evoked potentials. Acoustic analyzer disfunction, especially that of sound laterality, was discovered in 42-83% and 68% of patients, respectively. The hearing system was affected most frequently at the level of brain stem and occasionally at the level of the cochlea (15%). Sorption detoxication therapy produced response in 100% of patients by subjective and neurological criteria, while only in 59% by acoustic criteria. This disagreement is likely to reflect subclinical symptoms and may represent a prognostic value.
