BOTELHO, Marilia Silva e Nunes et al. Newborn hearing screening in the Limiar Clinic in Porto Velho - Rondônia. Braz. j. otorhinolaryngol. (Impr.) [online]. 2010, vol.76, n.5, pp. 605-610. ISSN 1808-8694. http://dx.doi.org/10.1590/S1808-86942010000500012.
With the universal hearing screening we can prevent auditory disorders in children. AIM: To characterize the program of neonatal auditory screening into a population of neonates. MATERIALS AND METHODS: longitudinal cohort study. We surveyed the clinic's database on neonatal auditory screening in the city of Porto Velho, Rondônia. RESULTS: Among the 6,889 newborns in the database, 5,700 (82.7%) passed and 1,189 (17.3%) failed the first screening. Of the group which failed 900 (75.7 %) returned for retesting. Among these, 15 (0.22 %) newborns had hearing loss confirmed. The most prevalent was neural hearing loss with 46.7% confirmed cases; they had hyperbilirubinemia as the most prevalent risk factor. CONCLUSION: hyperbilirubinemia was the most prevalent risk factor found in the group of hearing impaired children. The prevalence of hearing loss was of 2 in 1,000 newborns. It is important to highlight the relevant association between neural hearing loss caused by hyperbilirubinemia and sensorineural hearing loss of unknown causes.
