Sensorineural hearing loss is another type of hearing loss also known as SNHL or Sensor neural hearing loss. Mixed hearing loss is the type of hearing loss that conductive hearing loss and sensorineural hearing loss is in combination.

Sensorineural hearing loss may stem from the inner ear, the vestibulocochlear nerve, or the brain. Sensorineural hearing loss may occur due to a variety of factors that adversely affect the proper functioning of the ear.
Sensorineural hearing loss is a form of permanent hearing loss that originates with problems in the inner ear, the vestibulocochlear nerve, or the brain.
Also known as nerve deafness, sensorineural hearing loss may occur due to a variety of factors that adversely affect the proper functioning of the ear. Nerve deafness is usually considered an idiopathic condition, meaning there is no single, identifiable cause for its development.
Symptoms associated with sensorineural hearing loss are dependent on the age of the individual and the extent of the hearing loss upon diagnosis.
A diagnosis of nerve deafness may be confirmed with a complete medical history and an ear examination.
Treatment for sensorineural hearing loss may involve the use of a hearing device that fits just inside the ear. Cochlear implants are a prosthetic replacement for hearing and not considered a cure for hearing loss.
Complex in its composition, a cochlear implant is comprised of a microphone, speech processor, transmitter, stimulator, and receiver.
Following surgery, the individual may begin speech therapy and work closely with an audiologist and speech therapist.

As an overview, low frequency (or tone) sensorineural hearing loss (LF SNHL or LT SNHL) is unusual, and mainly reported in Meniere's disease as well as related conditions such as low CSF pressure. Le Prell et al (2011) suggested that low frequency hearing loss was detected in 2.7% of normal college student's ears. Oishi et al (2010) suggested that about half of patients with LTSNHL developed high or flat hearing loss within 10 years of onset. The new international criteria for Meniere's disease require observation of a low-tone SNHL.
Gatland et al (1991) reported fluctuation in hearing at low frequencies with dialysis was common, and suggested there might be treatment induced changes in fluid or electrolyte composition of endolymph (e.g.
Although OAE's are generally obliterated in patients with hearing loss > 30 dB, for any mechanism other than neural, this is not always the case in the low-tone SNHL associated with Meniere's disease.


The lack of universal correspondence between audios and OAE's in low-tone SNHL in at least some patients with Meniere's, suggests that the mechanism of hearing loss may not always be due to cochlear damage. Of course, in a different clinical context, one might wonder if the patient with the discrepency between OAE and audiogram might be pretending to have hearing loss. Papers are easy to publish about genetic hearing loss conditions, so the literature is somewhat oversupplied with these. Bespalova et al (2001) reported that low frequency SNHL may be associated with Wolfram syndrome, an autosomal recessive genetic disorder (diabetes insipidus, diabetes mellitus, optic atrophy, and deafness). Bramhall et al (2008) a reported that "the majority of hereditary LFSNHL is associated with heterozygous mutations in the WFS1 gene (wolframin protein). Eckert et al(2013) suggested that cerebral white matter hyperintensities predict low frequency hearing in older adults. Fukaya et al (1991) suggested that LFSN can be due to microinfarcts in the brainstem during surgery. Ito et al (1998) suggested that bilateral low-frequency SNHL suggested vertebrobasilar insufficiency. Yurtsever et al (2015) reported low and mid-frequency hearing loss in a single patient with Susac syndrome.
There are an immense number of reports of LTSNHL after spinal anesthesia and related conditions with low CSF pressure. Fog et al (1990) reported low frequency hearing loss in patients undergoing spinal anesthesia where a larger needle was used.
Waisted et al (1991) suggested that LFSNHL after spinal anesthesia was due to low perilymph pressure. Wang et al reported hearing reduction after prostate surgery with spinal anesthesia (1987). We have encountered a patient, about 50 years old, with a low-tone sensorineural hearing loss that occured in the context of a herpes zoster infection (Ramsay-Hunt). LTSNHL is generally viewed as either a variant of Meniere's disease or a variant of sudden hearing loss, and the same medications are used. To us, this seems a little overly stringent, compared to the earlier 1995 AAO criteria that just required any kind of hearing loss, but criteria are better than no criteria. That being said, genetic conditions should not be your first thought when you encounter a patient with LTSNHL. One would think that diabetes insipidus is so rare that hearing loss is probably not the main reason these individuals are seeking attention.
These patients are extremely rare because there isn't much microsurgery done close to the brainstem.
We are dubious about the conclusion of this paper because it is different than nearly every other paper in the literature.
We are dubious that this has any applicability to humans and we have never seen a patient with lithium toxicity with any LFSNHL.


We have observed this occasionally ourselves, but of course, the usual pattern is a conductive hyperacusis. We find this somewhat plausible as pregnancy and delivery might be associated with spinal anesthesia, with changes in collagen, and with gigantic changes in hormonal status. It’s mostly permanent because sensorineural hearing loss’ is very hard to be cured by medicals or surgery. There is a large literature about genetic causes, mainly in Wolfram's syndrome ( diabetes insipidus, diabetes mellitus, optic atrophy, and deafness), probably because it is relatively easier to publish articles about genetic problems.
He defined LTSNH as that the sum of the three low frequencies (125, 250, 500) was more than 100 dB, and the sum of the 3 high frequencies (2, 4, 8) was less than 60 dB. In other words, Wolfram's is probably not diagnosed mainly by ENT's or audiologists, but rather by renal medicine doctors, as DI is exceedingly rare, while LTSNHL is not so rare in hearing tests.
That being said, it is very rare to encounter any substantial change in hearing after pregnancy. Roughly speaking, the frequency patterns of hearing loss are divided up into: Low-frequency, mid-frequency, high-frequency, notches, and flat. Also it’s known that some drugs are making toxic effect and creating sensorineural hearing loss. There are lots of researches why depression is causing hearing impairment and it’s known that depression in every age may cause hearing loss. Living troubles on understanding what people say in standard sound is the most known symptom. Also listening TV on higher than normal volume continuously and depression based hearing loss are the main symptoms of hearing impartibility. Some deep head traumas may cause sensorineural hearing loss and also rarely but aging may cause it. Advances in hearing aid technology and cochlear implants are helping to improve communication for people affected by hearing loss.
You will be asked about other medical conditions and about what over-the-counter and prescription medications you take. You may be asked to cover one ear at a time while listening to sounds at different volumes.
Tests using a tuning fork can check if there is damage to the parts of the middle ear and eardrum that vibrate. However, the doctor will try to identify the cause of your hearing loss before treatment can begin.
