Abstract
BACKGROUND: There are many studies reported in the literature that have summarized audiological findings and possible rehabilitation in individuals with auditory neuropathy spectrum disorder (ANSD). However, there are very few studies that have attempted to delineate the gender differences in audiological characteristics and hearing aid benefit in individuals with ANSD.
PURPOSE: The study aimed to explore the differences between males and females in terms of demographic details, audiogram, speech identification scores, otoacoustic emissions, acoustic reflexes, long latency responses, and hearing aid benefit.
RESEARCH DESIGN: A retrospective study.
STUDY SAMPLE: A total of 255 individuals diagnosed with ANSD were selected for the study. The study included 137 females and 88 males.
DATA COLLECTION AND ANALYSIS: The demographic details, results of diagnostic audiological testing, and hearing aid benefit were analyzed retrospectively. The differences in findings across gender were compared.
RESULTS: The study shows that females have a relatively higher degree of hearing loss and that the majority of females show a rising type of audiometric configuration. The study shows that females have poorer speech perception abilities and experience limited benefits from hearing aids compared to males.
CONCLUSIONS: The results of the study show that there are gender differences in audiological findings and hearing aid benefits in individuals with ANSD. However, well-controlled prospective studies are essential to confirm the results obtained and to identify the possible mechanisms underlying the gender differences.
