title: [Objective topographic diagnosis of damage of the organ of hearing].
abstract: An analysis of the results of electrophysiologic examinations of hearing (impedance audiometry, BSER, MLR, SP) in 50 patients aged between 1 and 9 years perceptive bilateral hypoacusis reveals that the system of objective methods makes it possible not only the differentiation of cochlear and retrocochlear lesions, but also to demonstrate changes in upper part of the hearing tract. Electrophysiologic examinations of hearing help us to reveal the causes of failure in rehabilitation of speech and hearing and make possible to objectively study the conditions of hearing. In can be assumed that in the future combination of electrophysiologic methods with modern ways of imaging, changes in the nervous system will allow us to interpret by topographic diagnosis the results of EA examinations more deeply.
