A neural (retrocochlear) hearing loss occurs when the damage to the auditory system is b eyond the l vel of the cochlea, ranging anywhere f om the hearing ne ve up to the brain. A tumor on the hearing nerve can be one cause of a neural hearing loss. In sensorineural hearing losses, air conduction and bone conduction thresholds are both

Retrocochlear hearing loss is a term used to describe a neural or central hearing loss which occurs beyond the cochlea, affecting the vestibulocochlear nerve (auditory nerve) or central auditory system. What causes retrocochlear hearing loss? Although retrocochlear hearing disorders are rare, there are a variety of locations and causes of retrocochlear hearing loss.

Discrepancies between pure-tone audiograms and subjective hearing sensation and between pure-tone audiograms and ABR recordings were noted in 2 cases. These results suggest that varying degrees of retrocochlear involvement complicating the inner ear damage are the audiological characteristics of hearing loss following meningitis.

Since hearing loss correlates poorly with tumour size, a retrocochlear lesion is probably not the only cause for hearing loss. Also cochlear mechanisms seem to play a role.

Like ALHL, mid-frequency sudden deafness may be classified as another independent disease entity from idiopathic sudden deafness, which is defined as sudden-onset sensorineural hearing loss worse in the middle frequencies (1000-2000 Hz) than in the high (4000-8000 Hz) and low frequencies (250-500 Hz), representing a U-shaped or saucer-type …

Type II Continuous and pulsed tracings overlap up to 1000 Hz and then continuous tracing falls. Seen in cochlear loss.

Abstract. By far the most frequent cause of a retrocochlear lesion of the eighth nerve is acoustic neuroma. Despite the fact that acoustic neuromas almost always originate from the neurilemma of the vestibular ganglion, symptoms of the pars vestibularis of the eighth cranial nerve are rare at the beginning of the disease.

Noise-Induced Hearing Loss (NIHL) typically demonstrates a “knoch” on the audiogram at 4000k. Sounds around 85 dB for prolonged periods of time can cause hearing loss If you have to raise your voice to be heard, (normal conversation is around 60dB) you are most likely in an environment with at least 80 dB of noise.
