Introduction: The congenital hearing loss(present at birth) is the most common congenital disease,with an incidence of 1–3 cases/1,000 newborns (according to the data provided by NIDCD).
Objectives: The aim of this study is to establish the importance of the newborn hearing screening and the analysis of the risk factors for hearing loss.
Material and methods: This observational study,prospective,include a number of 18,336 newborns motherhood in Oradea in the period from January 2008–June 2012 with the gestational age between 27 and 42 weeks of gestation 5,134 premature and 13,202 newborns at term.
The method of screening used was by evoked transient acoustic oto-emissions(TEOAE) and automated auditory brainstem response(AABR) and,in parallel with it,the analysis of the risk factors for hearing loss at all newborns undergoing to the screening,as well as the telephonic screening of the newborns with risk factors for hearing loss.
Results: Of those 18,336 newborns undergoing to the screening 178 were detected “REFER” and 11 infants were diagnosed with sensorineural hearing loss. 4,600 neonates with risk factors detected "PASS" to the universal screening were subjected to the telephone screening,of which 3 infants were evaluated by hearing aid,of which 2 were diagnosed with sensorineural hearing loss.
Conclusion: The correct application of the protocol of screening and telephone monitoring of the infants with risk factors for a hearing loss early identify the existence of a congenital hearing loss. This fact is important because early diagnostic of the hearing loss allows appropriate treatment.
