- Abstract
Purpose. The aim of the study was to observe and to describe the evolution of early diagnosed hearing loss in children with neonatal auditory neuropathy spectrum disorders identified by universal neonatal hearing screening. Materials and method. In the last years, the development of universal auditory newborn screening program, that covers all maternities in our city, allowed us to test initially over 50,000 of babies and to identify and manage newborns with auditory neuropathy spectrum disorders after clinical audiological assessments. The follow-up was done for each child periodically until 18 months for cases fitted by hearing aids and until the cochlear implantation for cases with this indication. Results. We identified 26 children with auditory neuropathy spectrum disorders, six children with normal tonal hearing and 20 cases with different degrees of hearing loss. According to the results of our follow-up process, all children with normal tonal hearing kept their auditory status in time. All deaf children were hearing aid fitted, except the profound hearing loss with direct indication for cochlear implantation. In the group of children with hearing loss, we observed that 35% presented progressive forms and 15% presented fluctuating forms. 57% of progressive hearing loss group evolved to the profound deafness and cochlear implant indication. The greater the initial diagnosed degree of hearing loss, the more the children have progressed to profound deafness. Conclusions. A lot of children with auditory neuropathy spectrum disorders present progressive hearing loss, the profound form being finally present in more than 45% of cases. The periodical follow-up is essential in the first 18 months in order to offer the best medical indication and to avoid the delay of appropriate intervention for hearing rehabilitation and speech development.
