Auditory Neuropathy Spectrum Disorder

Auditory Neuropathy Spectrum Disorder is a rare condition wherein neural transmission through the VIIIth nerve and auditory brainstem is disrupted with intact peripheral hearing. Most frequently reported symptoms by individuals suffering from such conditions include impaired speech discrimination especially in presence of background noise. The aim of this single case study is to emphasize the effectiveness of channel-free technology as a rehabilitative option and to demonstrate the improvement in speech perception in noise with noise desensitisation training. A 24-year-old male patient reported to the National Institute of Speech and Hearing with the complaint of poor speech comprehension. The audiological profile revealed, bilateral moderate sensorineural hearing loss in pure tone audiometry with poor speech discrimination scores, bilateral ‘A’ type tympanogram with absent acoustic reflexes, good signal to noise ratio in otoacoustic emissions, and absent Auditory Brainstem Response at 95 dBnHL bilaterally suggestive of auditory neuropathy spectrum disorder in both the ears. As a part of rehabilitation, hearing aids with multiple channels and channel-free technology were tried and better speech discrimination scores were obtained with channel-free technology. In order to address poor speech discrimination in presence of noise, noise desensitisation training was given at different Signal to Noise Ratio with channel-free hearing aids and was found to be effective in improving the speech discrimination scores especially in adverse listening conditions. Key words: Auditory neuropathy spectrum disorder, Channel free hearing aid, Noise desensitisation.

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.

Abstract Introduction Auditory neuropathy spectrum disorder (ANSD) is a clinical condition in which individuals have normal cochlear responses and abnormal neural responses. There is a lack of evidence in the literature regarding the neural discrimination skill in individuals with ANSD, especially when the signal is presented in the presence of noise. Objectives The present study was performed with the aim to investigate auditory discrimination skill, in quiet and in the presence of noise, in individuals with ANSD and to compare the findings with normal-hearing individuals. Methods A total of 30 individuals with normal hearing sensitivity and 30 individuals with ANSD in the age range of 15 to 55 years old, with the mean age of 27.86 years old, were the participants. P300 response was recorded from both groups using syllable pairs /ba/-/da/ in oddball paradigm and the syllable /da/ in repetitive paradigm in quiet and at +10 dB signal-to-noise ratio (SNR). Results There was significant prolongation in latency and reaction time, and reduction in amplitude of P300 response and sensitivity in both groups with the addition of noise. The topographic pattern analysis showed activation of the central-parietal-occipital region of the brain in individuals with ANSD, whereas activation of the central-parietal region was observed in individuals with normal hearing. The activation was more diffused in individuals with ANSD compared with that of individuals with normal hearing. Conclusion The individuals with ANSD showed a significantly more adverse effect of noise on the neural discrimination skill than the normal counterpart.

Introduction The studies on hearing aid benefit in individuals with auditory neuropathy spectrum disorder (ANSD) shows limited benefit. Low cut modified amplification is found to be effective in few individuals with ANSD. With advancement in technology, receiver in the canal (RIC) hearing aids have proven to be more effective than traditional behind the ear (BTE) hearing aids. Objective Thus, the present study attempts to determine the effectiveness of low cut modified amplification using RIC and BTE. Method Twenty participants with ANSD were fitted with BTE and RIC using traditional and low cut modified amplification. We divided them into good and poor performers based on unaided speech identification scores (SIS). We then compared aided SIS and aided benefit across conditions in good and poor performers with ANSD across both conditions using BTE and RIC. Results The results of the study showed that the aided performance improved with low cut modified amplification in both BTE and RIC hearing aids. The improvement noticed with low-cut modified fitting with RIC was significant in more than BTE, especially in good performers with ANSD. Conclusion The improved clarity and naturalness of sound with RIC may have led to better aided scores and better acceptance of the hearing aid. Thus, low-cut modified amplification, preferably with RIC, needs to be attempted in fitting individuals with ANSD, especially in those with good unaided SIS in quiet.
