[Progress in phono-audiology: the deaf child].

Functional explorations, the physiopathology of the auditory pathways and centres, morphological investigations, molecular biology, and substitute processes make up the five major themes that best illustrate the progress achieved in phono-audiology. The management of the deaf child is characterized by early and multidisciplinary treatment. Thanks to the technical progress achieved in phono-audiology, the otorhinolaryngologist can apply a humanist medicine.
