All neonates admitted to the division of neonatology (level II and III), Amirkola children hospital, Babol, Iran included in this study between September 2006 and July 2008. At first stage all neonates before discharge were screened with portable Otoacoustic Emission (OAE) based on this examination. The results were divided in two groups: PASS and REFER. All babies who failed to respond bilateral referred for brain stem responses (ABR) 15 days later, and unilateral failure at 3 months of age. All neonates with severe and profound bilateral hearing loss received hearing aids at three months of age. These neonates were tested by ABR at nine months of age. In the case of no response they referred to cochlear implantation at 12 months of age. Findings
At first stage from 363 neonates, 311 (85.70%) passed the OAE exam. Fifty two (14.33%) referred for ABR (CI: 95%, 10.70-17.95). At the second stage 15 neonates (4.13%) diagnosed having severe to profound hearing loss (CI: %95, 108-6.19). Three neonates suffered from bilateral profound hearing loss and five neonates had bilateral sever hearing loss. Overalls 8 (2.2%) of screened babies needed hearing rehabilitation (CI: 95%, 0.69-3.73).Conclusion
