Abstract

Among 149 children (median age 23 months, range 2–123 months) examined by ECochG, a comparison was made between pure-tone and ECochG thresholds in 53 patients. By using linear regression analysis a high correlation was found (correlation coefficient 0.92, p< 0.0005) proving that ECochG gives valid estimates of the hearing thresholds, also in small children. A comparison between behavioral observation audiometry (BOA) and ECochG thresholds was performed in 62 children. It was concluded that BOA exhibits poor sensitivity in the assessment of hearing losses and underestimates their degree of severity. Furthermore, when BOA diagnoses normal hearing, there is a 9% risk of depriving a ‘deaf child of suitable treatment’.

Parmi 149 enfants, ayant entre 2 et 123 mois (âge moyen: 23 mois), que nous avons examines entre 1969 et 1979, nous avons pu effectuer chez 53 une comparaison des seuils en son pur et en ECochG. Par analyse de régression linéaire, nous avons trouvé une haute corrélation (coefficient de corrélation 0,92; p < 0,0005) ce qui nous amène à penser que l'ECochG est une méthode valable pour l'estimation des seuils auditifs chez les petits enfants.

Chez 62 enfants, nous avons comparé l'audiométrie de comportement (AC) et les seuils estimés en ECochG. Nous avons pu observer que l'AC présente une faible sensibilité dans l'évaluation de la perte auditive; elle sous-estime tout particulierement les pertes d'audition graves; ce qui nous conduit à établir à 9% le risque de priver un enfant sourd d'un traitement convenable lorsque l'AC fait apparaiˇtre une audition normale.
