Auditory neuropathy/auditory dyssynchrony (AN/AD) is a condition that affects the neural processing of auditory stimuli. Patients with AD/AN are able to respond to sounds accurately but their ability to decode speech and language is affected. AN/AD has only recently been described. In the late 1970s, clinical investigators began to describe groups of patients with normal or slightly elevated audiogram pure tone thresholds accompanied with absent or severely abnormal auditory brainstem responses (ABRs). With the advent of the otoacoustic emissions (OAEs) in the mid 1980s, these groups of patients were found to have normal cochlear function. The finding of normal cochlear function accompanied with abnormal brainstem responses was defined in 1996 as auditory neuropathy (AN). Whether this represents a true auditory nerve neuropathy is debatable. Further investigations led to the conclusion that AN may truly represent a dyssynchronous auditory nerve rather than a neuropathy. This finding gave rise to the newer term of auditory dyssynchrony (AD). [1] For the purposes of this summary, AN and AD are considered synonymous (ie, AN/AD). Now a days this condition commonly known as Auditory Neuropathy Spectrum Disorder (ANSD). Rather than just considering a condition some of researchers have labeled as syndrome. Treatment for ANSD is varies case to case and needs lot of trial and error method. Hearing aids have been effective of some of the cases where as cochlear implant is also being recommended strongly and found to be effective. Very short number of cases donot really benefits from above two option those advised to use communication strategies to be able to understand speech.
Pediatric Hearing Evaluation is one of the challenging task for every audiologist. Detailed case history, selection of appropriate physiological electrophysiological and behavioural testing is a key. Established hearing thresholds helps us select proper hearing aid and auditory training/ auditory verbal therapy approach. Child need to be evaluated subsequently to measure the benefit of amplification device and therapy. If no significant benefit is obtained by hearing aid further, child should be subjected to cochlear implant evaluation. Aided Audiogram, radiological study and therapists feedback helps team to consider the child for cochlear implant. Cochlear implant has really changed the world of children with hearing impairment. The goal of team is to integrate the child in mainstream and should get every opportunity as any other child with normal hearing. #brainstem evoked response #otoacoustic emission #Digital Hearing Aid #Aided audiogram #auditory Verbal therapy
Digital Hearing Aids A digital hearing aid is a hearing device that receives sound and digitally codes (breaks sound waves up into very small, discrete units) before it gets amplified. A traditional analog hearing aid simply makes the sound wave larger to amplify sounds. Digital Hearing Devices have really rewritten the history in Hearing aid industry. Digital Aids are available in behind the ear, In the canal, completely in the canal forms. An analog hearing aids can only amplify incoming sound, and cannot adjust it, analog hearing aids very often amplify distracting background noise, making it challenging to hear in noisy environments and nearly impossible to understand conversation over the phone. We promote only Digital hearing aids in our clinic.
What are Earmolds? When a individuals with hearing problem selects a hearing aid style—such as behind-the-ear (BTE) hearing aids—custom-fit earmolds are often needed to ensure optimum performance and comfort. An earmold is a acrylic or other soft material shaped to fit a individuals ear canal, and/or the outer ear structure (concha) surrounding the ear canal. Earmold styles vary according to level of hearing loss, and the style of hearing aid with which they're paired. In many cases, earmolds sit inside the ear canal, hidden from view. Other times, earmolds sit in the concha bowl as well as in the ear canal. Because earmolds worn in the concha so closely match the ear's natural contours and skin tone, they're hard to spot.
Acoustic Neuroma: Acoustic neuroma, also known as vestibular schwannoma, is a noncancerous and usually slow-growing tumor that develops on the main (vestibular) nerve leading from your inner ear to your brain. Branches of this nerve directly influence your balance and hearing, and pressure from an acoustic neuroma can cause hearing loss, ringing in your ear and unsteadiness. Diagnosis can be made using detailed audiological evaluation followed by radiological evaluation. Treatment widely depends on the size and site of lesion and damaged happed. Generally neurosurgeon and neurotolgist work together to manage the patient.
