Abstract

ANGRISANI, Rosanna Mariangela Giaffredo et al. Newborn Hearing Screening with otoacoustic emissions and cochlear-palpebral reflex: sensitivity and specificity study. Rev. CEFAC [online]. 2012, vol.14, n.5, pp. 844-852.  Epub Oct 14, 2011. ISSN 1982-0216.  http://dx.doi.org/10.1590/S1516-18462011005000108.

PURPOSE: to study the specificity and sensitivity of NHS with otoacoustic emissions transient stimulus (TEOAE) associated with cochlear-palpebral reflex (CPR), and comparing the results of Auditory Evoked Potential (BAEP). METHOD: three hundred and sixty-nine neonates under risk of hearing loss were evaluated. Evaluation procedures consisted of transient otocoustic emissions(TOAEs), cochlear-palpebral reflex (CPR), and ABR diagnostic carried out in the same week. RESULTS: the incidence in the general population was 4 neonates (1.1%) with cochlear hearing loss, 22 (5.9%) with conductive hearing loss, 2 (0.5%) with auditory neuropathy, 14 (3.8%) with central abnormalities and 15 (4.1%) with delayed maturation of the auditory pathway. The TAN showed 100% sensitivity and 94.6% specificity in detecting the spectrum of cochlear and auditory neuropathy, 77.3% sensitivity and 94.6% specificity in detecting conductive and 42.9% and 94.6% specificity while detecting central abnormalities. All findings showed statistically significant differences when compared to normal auditory neonates. CONCLUSION: this protocol was effective to detect in neonates with cochlear hearing loss and auditory neuropathy with high sensitivity and specificity.
