Contralateral suppression of transient evoked otoacoustic emissions in children with auditory processing disorder.

This study concerns contralateral white noise suppression of transient evoked otoacoustic emissions (TEOAEs) in children with auditory processing disorder (APD). Fifty-one children between 7 and 11 years were assigned to 1 of 3 experimental groups: those without auditory complaints (n = 15), those with APD who scored high on a standardized test (n = 20) and those with APD who scored lower on the same test (n = 16). For all groups TEOAE suppression was determined in both linear and nonlinear acquisition mode. The results provide evidence that abnormal TEOAE suppression was significantly more common in the APD groups than in the control group. Contralateral suppression of TEOAE is an additional tool for assessing the efferent pathway in children with APD.

Hearing loss is the more frequent sequel of bacterial meningitis in children. This study describes the audiological profile (peripheric and central) of 89 children admitted to the hospital wards with the diagnosis of bacterial meningitis. Those children attended audiological follow up, after their hospital discharge, and were submitted to audiological tests. The results showed that 85.4% among them presented normal hearing in both ears 10.1% presented bilateral neurosensorial hearing loss and 4.5% presented unilateral neurosensorial hearing loss. The results from the auditory processing skills assessment showed that 10% of those children presented auditory localization and recognition of sentences with competitive messages (Paediatric Sentences Identification-ipsilateral) disorders.
