RADO-TRIVENO, Julia  and  ALEN-AYCA, Jaime. Evaluation of otoacoustic emissions in relation to brainstem evoked auditory potentials in children. Rev. perú. med. exp. salud publica [online]. 2016, vol.33, n.4, pp.706-712. ISSN 1726-4634.

To determine the validity of the use of acoustic otoacoustic emissions in comparison with the evoked potentials Auditory brainstem examination (PEATC), a study was carried out with 96 children between 0 and 4 years of age that went to Instituto Nacional de Rehabilitación in Lima, Peru. The results show a cut-off point corresponding to 1 in (+): 17.67 in right ear and 16.72 in left ear, and LR (-): 0.25 in ear right and 0.24 in left ear; ROC curve with area under the right ear curve of 0.830 (p<0.001) was obtained and in left ear of 0.829 (p<0.001). According to the results of LR (+) the sensitivity is 76% in the right ear and 65% In the left ear that coincides with the conformation of the ROC curve. In conclusion, acoustic emissions would not represent an alternative sufficiently discriminatory alternative as a screening test in this population.
