Description

<p>Because early childhood is a critical period for language acquisition, the presence of hearing loss can result in significant delays in language development. In this study, we conducted a screening using the Titan interacoustics tympanometer (226 Hz) and distortion product otoacoustic emissions in kindergarten children in Ishikawa Prefecture and verified that this method was effective in ear disease screening in early childhood. Of the 65 children eligible, the REFER rate was 18.5%. Excluding eustachian tube stenosis, the positive predictive value of the workup was 44.4%. The screening method used in our study allowed for the identification of twice as many children with hearing loss compared to those identified using the screening method of the Ministry of Health, Labor and Welfare. It is noteworthy that our method was able to detect unilateral otitis media with effusion, which is not able to be detected using the Ministry of Health, Labor and Welfare method. By further developing this research, we hope to detect hearing loss in as many children as possible who otherwise would receive a “pass” when tested using conventional hearing screening methods conducted by the Ministry of Health, Labor and Welfare and provide options for treatments for hearing loss and language development.</p>
