[Experience of the ENT clinic--rehabilitation hospital of Iaşi in the diagnosis of hearing loss in children between 1 and 5 years of age].
The aim of this study is to asses the average age of diagnosis of congenital hearing loss in children up to 5 years old. A group of 48 children aged between 1-5 years old were admitted in our clinic in 2005 because of hearing impairment, noticed in most cases by their parents. All cases were investigated in our clinic by transient evoked oto-acoustic emission test, threshold auditory brainstem response, impedance-metry and, whenever possible, audiometry. Sensori-neural hearing loss of variable gravity was diagnosed in 30 cases, most of them in the 2-3 yrs group of age (9 cases). The etiology of hearing loss could be established in 9 cases only. 19 patients (63%) were hearing aided, but follow-up was not possible. The average age of congenital hearing loss diagnosis may be reduced by applying universal neonatal hearing screening and a well established modality of confirmation of deafness in infants identified by the universal screening.
