Abstract
Auditory neuropathy is a type of hearing loss. This is a case study that describes an 18 months old child presenting with hearing loss reported by his parents. The parents reported that although he exhibited signs of hearing loss, they were told by multiple experts that tests confirmed that he was not deaf. The child sometimes acted as if he was deaf and sometimes did not, which lead to confusion about additional diagnoses that might be included in the diagnosis. An early diagnosis of auditory neuropathy is time sensitive as early development of learning and language is more beneficial for the child. Listening to parents and understanding the subtleties that segregate the diagnosis of auditory neuropathy from auditory processing disorder, autism or other similar presentations is important in the diagnosis and treatment of auditory neuropathy in children.
Highlights
Auditory neuropathy is a disorder that effects the neural processing of auditory stimuli in the brain and does so either directly or indirectly [1]
The patient had multiple complications, his otoacoustic emissions (OAE) was present when tested at 48 hours after admission to the NICU and he was not suspected as having a hearing disorder
The patient presented in this case study had gone through multiple tests for hearing including the newborn screening in which he had otoacoustic exam (OAE)’s present at that time and later were absent with testing at the Callier Center
Summary
Auditory neuropathy is a disorder that effects the neural processing of auditory stimuli in the brain and does so either directly or indirectly [1]. Dowley et al [2] explain that auditory neuropathy is a disorder of the cochlear inner hair-cell and/or eighth-nerve function. AN is the main cause of hearing impairment in about 10% or more of deaf patients [3]. The tests that are considered the most useful consist of the otoacoustic exam (OAE), auditory brainstem response (ABR), and middle ear reflex (MEMR) [4].
