Abstract

A systematic follow-up of children diagnosed as deaf may reveal additional pertinent information which may be instrumental in ascertaining the cause of deafness. 107 deaf children were detected by a prospective study of 62 000 children screened for deafness during 11 years. The cause of deafness could be determined in 63 children while in 44 no etiology was apparent. Investigation of the 44 children revealed a genetic origin of deafness in 12 additional children. Consanguinity was evident in the children whose deafness was of genetic origin. Identification of the cause of deafness in children contributes to prevention of this handicap.

Une surveillance systématique des enfants diagnostiqués comme sourds peut donner des informations supplémentaires sur la cause de la surdité. 107 enfants sourds furent dépistés graˇce à une étude prospective menée sur 62 000 enfants en ll ans. La cause de la surdité a pu ětre identifiée dans 63 cas, aucune étiologie ne pouvant ětre décelée dans les 44 autres. Une enquěte sur ces 44 sujets révéla une origine génétique chez 12 enfants supplémentaires. Dans le groupe des surdités d'origine génétique, la consanguinité était évidente. L'identification de la cause de la surdité chez les enfants contribue à la prévention de cet handicap.
