Audiologic Assessment of Preschool Children with Hearing Loss in a Secondary Health Care Setting
The study aimed to evaluate the audiologic profile of preschool children with hearing loss, i.e., to determine the type, degree, and configuration of hearing loss, amplitude of otoacoustic emissions, and word recognition performance. This retrospective study included 260 children examined in a secondary healthcare setting. For statistical data analysis, we used the Chi-square test with a level of significance p < 0.05. Conductive, sensorineural, and mixed hearing loss was present in 93.1%, 4.6%, and 2.3%, respectively. Mild hearing loss was present in 96.1%, moderate in 2.3%, and severe hearing loss in 1.6%. Type B tympanogram was the most common (p = 0.00001). The mean amplitude of otoacoustic emissions was -7.6 dB in sensorineural hearing loss and 12.3 dB in normal hearing. The maximum word recognition score was frequently obtained at presentation levels of 25-40 dB SL (p = 0.009). The majority of children had mild conductive hearing loss with normal word recognition ability.
