One hunderd deaf children underwent a clinical evaluation 6 months-2 years after they had been examined by means of electrocochleography. The purpose of this study was to evaluate the long-term effects of the hearing aids on child speech development. Data concerning the use of the hearing aid (age of fitting, daily use, ear mold, gain setting) were collected through a questionnaire which also included information about family, school, rehabilitative program and associated pathologies. The questionnaires were compiled by the authors in cooperation with the child's relatives. Two multiple level scales were designed to assess speech development and comprehension as a result of the phoniatric evaluation. In spite of large differences in the methods and times in which rehabilitation was initiated, the main result of this study is an evident relationship between speech and appropriate amplification. However, the advantage of amplification is frequently reduced by an inappropriate ear mold, or by a concomitant long-lasting middle ear pathology. These results demonstrate the need for a follow-up procedure which can allow the deaf child to take the maximum advantage of the hearing aid.
