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.
DiMarco uses the universal language of dance to change the hearing world’s perception of what it means to be Deaf – and he just might win the Mirrorball trophy in the process. Wearing hearing aids has been such a positive experience for Marie Redfern, she wants to encourage others with hearing loss to try them, too.
The balance organ is part of the inner ear, although the sense of balance actually comes from the coordination of three different body senses: the balance organ in the inner ear, the visual system and the muscles and joints in the body. Dizziness related to the inner ear is one of the most common types and it results from disturbances in the blood circulation or fluid pressure in the inner ear, pressure on the balance nerve or physiologic changes in the balance nerve.


This dizziness caused by the inner ear may feel like a whirling or spinning sensation (vertigo), unsteadiness or lightheadedness and it may be constant or intermittent. There are many other causes of dizziness which are not related to the function of the inner ear. Because the inner ear is the most common cause of dizziness, the first place to start with an evaluation is often a hearing test. Other tests to evaluate dizziness may be performed by a physical therapist, cardiologist or neurologist.
Appropriate treatment for dizzy symptoms will depend on the underlying cause, so it is important that you see a physician for any of these symptoms. When part of your balance system is afflicted, the other parts can usually compensate for the deficit. 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.
Dizziness is what happens when there is a deficit in any of these three senses or the brain centers that tie them all together. If the brain is not able to coordinate the inputs from the three parts of the balance system, there is central dizziness.
The cochlea, our hearing organ, is contained within the same bony structure as the balance organ.
Usually performed by an ENT physician or an audiologist, a VNG test uses video cameras to record eye movements while a patient tracks a visual stimulus, is moved into different positions and while the ear canals are stimulated with warm and cool air or water. As there are many systems involved in balance, there are many possible underlying causes for dizziness and many medical specialties that may be involved.
A physician might prescribe something to mitigate the dizzy symptoms temporarily but that medication must be discontinued at least 24 hours prior to an evaluation.

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. Although nausea and vomiting may occur, one does not lose consciousness as a result of inner ear dizziness.
Central dizziness may be caused by migraines, tumors, infections and degenerative diseases like multiple sclerosis. A behavioral hearing test in a sound booth may be followed by an Auditory Brainstem Response (ABR) test.
This test gives a broad picture of whether the underlying issue is related to the inner ear or not. Common causes of dizziness due to inner ear deficits include Meniere’s disease, bacterial or viral infection of the inner ear, benign paroxysmal positional vertigo (BPPV), motion sickness, allergies, medications and circulatory conditions.
In the case of medical conditions, like allergies, thyroid deficiency and diabetes, regulation of the condition will eliminate the dizziness.
For example, if you must take an ototoxic drug that destroys the balance organs of the inner ear, you can still stay quite balanced as long as your eyes are open. Roughly speaking, the frequency patterns of hearing loss are divided up into: Low-frequency, mid-frequency, high-frequency, notches, and flat. The pattern of the symptoms experienced will depend on which functions of the inner ear are affected. Visual dizziness can occur if the eye muscles are imbalanced or there are errors of refraction, such as when you borrow a pair of eyeglasses from a friend with a different prescription. If you have recently changed or added a prescription to your daily routine, be sure to ask your physician about the possibility of dizziness as a side-effect. Many disorders can be treated with medication, surgery, diet, lifestyle changes or some combination of these. However, when you are asked to close your eyes, you may find it quite difficult to stay standing upright.
Other causes of visual dizziness include intermittent inability to focus the eyes, difficulty reading or intermittent blurring of vision.
There are also physical therapists who specialize in vestibular rehabilitation, which is a treatment for balance disorders that gradually retrains the brain to compensate for lost sensory input from the balance system. Even though your body will work to compensate the immediate loss, don’t wait to seek help. Very rarely, dizzy symptoms may be caused by muscle or joint issues, such as unsteadiness due to muscular dystrophy. The presence or absence of hearing loss or auditory brainstem anomalies will provide clues to the physician about the cause of your symptoms. For extreme cases, surgery may be warranted or a suppressant such as Valium may be prescribed to relieve the symptom. If you experience any dizziness symptoms, you should talk to your physician or a hearing healthcare professional immediately so the underlying cause can be determined and the problem remediated. General health problems, such as diabetes, thyroid deficiency, vitamin deficiency, anemia and arterial blockage can cause dizziness as well.
