[Neurophysiologic tests for the early detection of deafness in children].

Using brainstem auditory evoked potentials and tympanometry the authors have examined 120 children aging from several months to five years and they have found a high percentage of children with hearing impairment with sensorineural deafness. The children had also secretory inflammation of the middle ear. It has been suggested that secretory inflammation of the middle ear deteriorates the basic hearing impairment because of which it should be early diagnosed and surgically treated. Owing to the complex problem of children deafness, the authors recommend that several methods of examination should be applied in the diagnostic procedure in order to determine precisely the auditory threshold and to initiate in time hearing and speech habilitation.
