Abstract

Purpose: The purpose of this study was to evaluate the auditory brainstem response (ABR) of infants with asymmetric intrauterine growth restriction (IUGR) in response to different stimuli and to compare the findings with those of term infants.

Method: A total of 20 infants with asymmetric IUGR who had no risk factors for hearing loss and 20 term healthy infants as a control group participated. Click, chirp, and 4-kHz tone burst at 90 dB nHL stimuli were used, and Waves I, III, and V absolute latencies; Waves I-III, I-V, and III-V interpeak intervals; and wave amplitudes were evaluated.

Results: The Wave V absolute latency and Waves I-V interpeak interval of both click and chirp stimuli in infants with asymmetric IUGR were significantly shorter in both ears (p < .05). In contrast, only Wave III absolute latency was significantly shorter for both ears (p < .05) with a 4-kHz tone burst.

Conclusions: ABR test with click, chirp, and 4-kHz tone-burst stimuli revealed that there are functional differences attributed to IUGR. Contrary to popular belief, these findings are evidence of neurosensory changes caused by IUGR, which is not included as a risk factor in newborn hearing screening programs. The type of stimulus used in the assessment was critical.

期刊介绍： Mission: AJA publishes peer-reviewed research and other scholarly articles pertaining to clinical audiology methods and issues, and serves as an outlet for discussion of related professional and educational issues and ideas. The journal is an international outlet for research on clinical research pertaining to screening, diagnosis, management and outcomes of hearing and balance disorders as well as the etiologies and characteristics of these disorders. The clinical orientation of the journal allows for the publication of reports on audiology as implemented nationally and internationally, including novel clinical procedures, approaches, and cases. AJA seeks to advance evidence-based practice by disseminating the results of new studies as well as providing a forum for critical reviews and meta-analyses of previously published work. Scope: The broad field of clinical audiology, including audiologic/aural rehabilitation; balance and balance disorders; cultural and linguistic diversity; detection, diagnosis, prevention, habilitation, rehabilitation, and monitoring of hearing loss; hearing aids, cochlear implants, and hearing-assistive technology; hearing disorders; lifespan perspectives on auditory function; speech perception; and tinnitus.
