Objectives: Hearing loss is one of the most common congenital anomalies. Its detection and early intervention are crucial to the appropriate verbal, cognitive, behavioural and cognitive development. This study aimed to evaluate the neonatal hearing screening preformed at the Hospital S. João in the first 12 months since its implementation.
Study Design: Retrospective study
Material and Methods: Newborns infants admitted in the Well baby and Neonatal Intensive Care Unit (NICU) submitted to audiometric evaluation by otoacoustic emissions complemented, whenever necessary, by brainstem auditory evoked potentials.
Results: The global coverage in the Maternity was 96% (2373) newborns from the initial population. One hundred and eight cases were lost. Three newborns presented with unilateral deafness and none had bilateral deafness. In the NICU, 175 (83%) newborns were evaluated. Five were diagnosed with bilateral deafness and one unilateral.
Conclusions: Neonatal hearing screening in all newborns, healthy or with risk factors is critical in early detection of hearing anomalies and the subsequent intervention.
