Triagem auditiva neonatal com emissão otoacústica transiente utilizando estímulo de banda estreita

Abstract

Research Funding: study funded by CAPES Conflict of interest: non-existent conduction, its sensitivity (efficacy) and specificity (efficiency) determined by the employed techniques are extremely important 6 . Literature has shown that the Transient Evoked Otoacoustic emissions Test (TEOAE) is the procedure deemed adequate for NHS, as it is a low-cost procedure that uses a weak intensity acoustic stimulus covering a wide frequency range, and also for being a quick and simple procedure 7-9 .However, one of the main difficulties in registering the TEOAE during NHS is typically the effect of noise 8

Epidemiological Profile of Neonates in Hearing Screening at a Maternity of a Tertiary Hospital in the state of Santa Catarina, Brazil

“…7,8 Thus, both the activity state and the physiological processes can cause a weak response level of otoacoustic emissions. 7 As recommended by the American Academy of Pediatrics, the quality model for NHS programs states that the percentage of false positives in screening should not exceed 3%. 9 However, this amount is still not reached, affecting the quality of the programs, in addition to medical and transportation expenses, and causing suffering to the parents--due to the worry and uncertainty regarding the health of their child.…”

“…The main obstacle in registering OAE is environmental noise, since not all places have the ideal acoustic pattern. 7 Other factors that might also interfere with test results are: sneezing, movement, the evaluator's experience with the equipment used, the number of neonates previously evaluated by the professional, among others. 7 8 Thus, both the activity state and the physiological processes can cause a weak response level of otoacoustic emissions.…”
