Auditory Neuropathy/Dys-synchrony with Secondary Loss of Otoacoustic Emissions in a Child with Autism
نویسندگان
چکیده
Otoacoustic emissions are commonly present in cases of auditory neuropathy/dys-synchrony; however, otoacoustic emissions are absent or disappear in approximately one-third of patients with the disorder. Failure to identify AN/AD patients with absent otoacoustic emissions may result in improper diagnosis and management. The purpose of this article is to present fi ndings from a case of auditory neuropathy/dys-synchrony with secondary loss of otoacoustic emissions to increase clinician awareness regarding the relationship between otoacoustic emissions and the disorder.

Patients with auditory neuropathy/dys-synchrony lack efferent suppression of transient evoked otoacoustic emissions.
Function of the olivocochlear reflex, measured by suppression of transient evoked otoacoustic emissions, is assessed in nine patients with bilateral auditory neuropathy/dys-synchrony and compared to matched control subjects with normal auditory function. TEOAEs were acquired using 65 dB peak sound pressure linear clicks with and without the presence of broad-band noise presented binaurally, ips...

OBJECTIVE The purpose of the present study was to investigate the relationship between cortical processing of speech and benefit from hearing aids in individuals with auditory dys-synchrony. MATERIALS AND METHODS Data were collected from 38 individuals with auditory dys-synchrony. Participants were selected based on hearing thresholds, middle ear reflexes, otoacoustic emissions, and auditory ...
متن کاملIdentification of a novel pathogenic OTOF variant causative of nonsyndromic hearing loss with high frequency in the Ashkenazi Jewish population
Mutations in the OTOF gene have previously been shown to cause nonsyndromic prelingual deafness (DFNB9, OMIM 601071) as well as auditory neuropathy/dys-synchrony. In this study, the OTOF NM_194248.2 c.5332G>T, p.Val1778Phe variant was identified in a large Ashkenazi Jewish family as the causative variant in four siblings with hearing loss. Our analysis reveals a carrier frequency of the OTOF c....
متن کاملAuditory neuropathy/dys-synchrony: diagnosis and management.
Auditory brainstem responses (ABRs) and otoacoustic emissions (OAEs) are objective measures of auditory function, but are not hearing tests. Normal OAEs reflect normal cochlear outer hair cell function, and an ABR indicates a synchronous neural response. It is quite possible for a patient to have normal OAEs but absent or grossly abnormal ABR and a behavioral audiogram that is inconsistent with...
متن کاملAbsent or elevated middle ear muscle reflexes in the presence of normal otoacoustic emissions: a universal finding in 136 cases of auditory neuropathy/dys-synchrony.
We extracted a subpopulation of 136 patients (from our database of 257 AN/AD subjects) in whom middle ear muscle reflexes had been measured. None showed normal reflexes at all frequencies tested. Only three subjects showed any reflexes at 95 dB HL or below, but never at both 1 and 2 kHz in both ears whether ipsilaterally or contralaterally elicited. All the other reflex measures in these remain...
