Aim. The aim of this study, was to evaluate the validity of the otoacustic emissions methodology in a mass screening, which is still being carried out by the Audiology Service of the ENT Department, “C. Poma” Hospital in Mantova on all newborns, in order to verify the specificity of the system and reduce to a minimum number the false alarms without invalidating its reliability.
Methods. At the Audiology Service of the ENT Department, “C. Poma” Hospital in Mantova, from July 2000 to June 2002 we have screened, with TEOAE, 2 864 newborns, who represent the 100% of newborns in the last 24 months. The subjects tested are born at term (2 448 subjects), and preterm or new borns pathological newborns admitted to the Service of Neonatal Pathology (416 subjects). The recording of TEOAE has been made by Echoport-Othodynamics ILO 288 Analyzer with Quickscreen modality.
Results. Only 0,53% of the 2 448 at term newborns showed to be “fail” at step III with only 2 brainstem pathological responses (0,08%). Only 3.4% of the 416 newborns found “fail” at step III with 6 brainstem pathological responses (1.4%).
Conclusion. The results obtained show that TEAOE is a reliable test for the newborn screening and allow to discriminate quickly and at a low cost the hearing loss and normal and pathological subjects.
