Achados na triagem imitanciométrica e de processamento auditivo em escolares

Purpose: to check acoustic immittance screening findings and results of the simplified evaluation of auditory processing in school children.
Method: the subjects under this study were students from the 1st to the 4th grade, with ages ranging from seven to ten year-old, from a public school in Porto Alegre. 130 students were evaluated in the immitance screening, which consisted of a tympanometry and an ipsilateral acoustic reflex, and a simplified evaluation of auditory processing. This also involved the tests of sound localization, and verbal and non-verbal sequential memory.
Results: in the screening immittance, 43.08% of the students passed and the type A curve was the most frequent. The acoustic reflex at 4000 Hz had a lower percentage of appearance when compared to the other frequencies. In the simplified evaluation of auditory processing test, 76.15% of the children passed. Moreover, it was observed that the worst performance of the evaluated students was found in the verbal sequential memory test.
Conclusion: the type A tympanometric curve was the most frequent in this population. In the simplified evaluation of auditory processing, most subjects passed, obtaining higher frequency of correct answers in the sound localization test. No statistical association between the results of the immittance screening and the simplified evaluation of auditory processing was found.
