Frequency: The sound frequency or pitch (measured in Hertz) is plotted on the X (horizontal) axis. Intensity: The sound Intensity or loudness (measured in decibels) is plotted on the Y (vertical) axis.
The softest sound a person hears 50% of the times, at each frequency is his Hearing Threshold at that frequency.
The difference between the air conduction thresholds of the right and left ear is more than 40db. By comparing the air conduction and bone conduction thresholds, we can determine if the hearing loss is conductive, sensorineural or mixed. The audiogram shows normal bone conduction thresholds while the air conduction thresholds show a hearing loss greater than 20db (remember 0- 20 db is normal range). Examples: Wax, glue ear, otitis media, perforation of the tympanic membrane, or ossicular abnormalities.
Both the air and bone conduction thresholds are above 20db but the difference between the air and bone conduction threshold is more than 10db.

Type B: Is a flat, horizontal trace, indicating fluid in the middle ear (in the presence of normal ear canal Volume). The authors of this document have attempted to provide information that is medically sound and up-to-date. Affecting the inner ear, Meniere's disease is a condition that causes vertigo (attacks of a spinning sensation), hearing loss, tinnitus (a roaring, buzzing, or ringing sound in the ear), and a sensation of fullness in the affected ear. NOTE: This information is not intended to substitute for a consultation with your physician. Nakashima et al (2007) imaged the inner ear of several patients using intratympanic gadolinium and reported that in patients with endolymphatic hydrops, the perilymphatic space surrounding the endolymph was small or had disappeared.
There is also skepticism that part of the hydrops hypothesis, ruptures of membranes, is correct. Areweiler-Harbeck reported that 19% of 193 patients with Meniere's had a positive family history. This is a controversial topic due to the highly litigeous nature of symptoms after head injuries.
Heavy exposure to impulse noise (such as gun fire) has been suggested by some as a cause of inner ear disease and symptoms resembling Meniere's disease. Some have suggested that hydrops might be caused by obstruction of the duct reunions by loose saccular otoconia (Yamane et al, 2010; 2014). The inner ear fluid is connected to the spinal fluid through several channels, and low spinal fluid pressure might reasonably be a source of hydrops.

Wu Q1, Dai C1, Zhao M2, Sha Y2.The correlation between symptoms of definite Meniere's disease and endolymphatic hydrops visualized by magnetic resonance imaging. There are many sides to tinnitus suffering, but one of the more serious conditions that can physically cause aches, pains, and frustration is called Meniere’s Disease.
An attack typically starts with ear pressure as if the ears were full of water and being pushed on.
Injury tends to remove the “control” aspect of your ears inner workings causing fluid to no longer stay constant but rather to change with the body’s own fluids and blood pressures. Many have attacks in close proximity to one another causing great frustration and making anything being done at the time increasingly difficult. Overall you want to maintain a low sodium diet, no caffeine, and keep sugary foods to a minimum. For some Meniere’s Disease can be permanent and managing it is the best you can hope for, but the condition is well known and easy to manage if you have the right information and put forth the effort to keep your diet under control. Meniere's Disease is thought to be triggered by immune reactions, metabolic disturbances within the inner ear, inner ear infections or trauma, possible allergic conditions, and other injures to the inner ear. Hearing loss is generally most pronounced in the lower frequencies and is accompanied by a distinct sensation of pressure, fullness or a stopped-up feeling in the ear. Sea shell-like roaring, ringing or bell-like noises in the ear (tinnitus) can be extremely distracting and bothersome. The clinical symptoms of Meniere's disease are thought to be caused by an increase in the fluid pressure within the delicate membranes of the inner ear. The classic theory is that during a Meniere's spell, the delicate membranes within the inner ear (cochlea) rupture. Unfortunately, the sudden disruption of the normal inner ear tissues leads to injury of the tiny hair cells that are responsible for hearing and balance. In some patients, Meniere's disease is only intermittently bothersome and takes an overall mild course. Periods of increased symptoms, which are unpredictable and occur without warning, may be followed by long periods of improvement or even complete remission. Some blood tests are available to help rule out autoimmune inner ear disease that may simulate Meniere's Disease. The history and quality of symptoms are very important in making the diagnosis of Meniere's disease. On physical examination, the eardrums and neurological exam are usually normal, especially between the acute episodes of dizziness.
A new test, vestibular evoked myopotentials, VEMP, are now being used to test patients who are suspected of having Meniere's Disease. High resolution CT scans may be performed to rule out superior semi-circular dehiscence syndrome (SSCDS). Measurements of hemoglobin, blood sugar (glucose), cholesterol, immune system status, liver, kidney, thyroid function testing, and testing for infectious diseases such as syphilis, lyme disease, and infectious mononucleosis may be among the studies needed to rule out other conditions that may cause symptoms similar to those found in Meniere's disease. Medical treatment is directed towards decreasing the frequency of attacks, stabilizing the hearing, and managing the episodes of vertigo when they occur. Medication(s) may be prescribed to reduce the severity of symptoms and possibly to decrease the frequency of Meniere's spells. A recent treatment for patients with Meniere's Disease that is effecting both ears (Bilateral Meniere's Disease) is the administration of oral methotrexate in low, weekly doses. Vestibular (balance) rehabilitation programs may be useful in helping to adjust to the loss of balance function that is often seen in more advanced cases of Meniere's disease. Endolymphatic sac decompression is a surgical procedure performed to treat intractable Meniere's disease. Other surgical procedures are available to treat Meniere's disease but must be tailored to the patient's individual needs and circumstances.
For most patients with Meniere's Disease, a combination of lifestyle changes and medication leads to significant improvement.
In the last few years, a minimally invasive procedure has been developed that can lead to a significant relief of vertigo with less surgical risk. Gentamicin is a common antibiotic that has been used for many years to treat serious bacterial infections intravenously.
Both of these medications can be toxic when the large doses are given orally or intravenously. Middle ear perfusion treatment of the inner ear with these medications has been performed at both academic and clinical medical centers in the United States. The success of Middle Ear Perfusion has been aided by advances in carbon dioxide lasers, fiberoptic endoscopic technology, and high definition video imaging.
Dexamethasone seems to be most effective in patients with early Meniere's disease who have tinnitus, fluctuating hearing loss, and dizzy spells. Middle Ear Perfusion is a promising treatment for Meniere's disease that does not respond to medical therapy.

It is the softest sound that a person with normal hearing would be able to hear at least 50% of the times. It is done to prevent nontest ear from detecting the sound presented to the test ear by crossover. The compliance (inverse of stiffness) of the tympano-ossicular system is charted against various pressure changes.
Because Meniere's disease affects each person differently, your doctor will suggest strategies to help reduce your symptoms and will help you choose the treatment that is best for you.What is Meniere's Disease?Meniere's disease, also called idiopathic endolymphatic hydrops, is a disorder of the inner ear. It is offered to educate the patient and his or her family on the basis of otolaryngology conditions in order to get the most out of their office visits and consultations. A recent variant is to propose that hydrops is due to blockage of the reuniting duct, which is located at the bottom of the saccule (Yamane et al, 2010).
Foster and Breeze(2013) recently published a literature review and suggested that published literature evidence supported the hypothesis that hydrops causes Meniere's disease. That being said, there is nevertheless very good evidence that hydrops (at least) correlates with symptoms of Meniere's. It is the author's opinion that although this is not always the case, this may be true in a substantial number of people, and perhaps about 20% of cases of Meniere's are actually misdiagnosed Migraine. We suspect that Pulec's data was based on patients from far in the past, when there was a higher percentage of persons in the population with previous exposure to syphilis than the present. There could easily be 50 different locii that can produce symptoms that fit into the commitee criteria for Meniere's disease. This study suggests that familial Meniere's may be less common in Korea than in the rest of the world.
These tiny family studies mean very little by themselves -- once there are a hundred of these, there might be some conclusions to draw. In view of the present feeling that hydrops may not be the key pathology in Meniere's at all, these ideas may need revision.
As an overview, the literature is not definitive about the connection between Meniere's disease and trauma. There are also cases reported of Meniere's after temporal bone fracture, and even simply acceleration-decelleration injuries (Dibiase and Arriaga, 1997).
There is some controversy here however, and one very large study of 17,245 Israeli veterans suggested that there was no effect (Segal and Eviatar, 2003).

Typically, those with this type of tinnitus get attacks, much like panic attacks but more physical and geared in the ears. It’s incredibly taxing to the energy and comfort levels often leading to prolonged naps from exhaustion. Normally, this fluid stays at a consistent rate and contains concentrations of sodium, potassium, chloride, and electrolytes which allow the inner ear sensory cells to function the way they are supposed to.
This means stress, for example, can cause intense pain in the ears as can exercising and times when the heart is pumping harder than usual. Things like taking in high salt or sugary diets, this increase can dis-balance the inner ear fluids. You must change your diet to help balance and maintain a good balance of the inner ear fluids. If possible, eliminate alcohol and tobacco completely- these also agitate the condition and can make it much worse. Many canned foods contain a lot of sugar so it’s not just about avoiding candy and soft drinks! The mixing of inner ear fluids results in a sudden electrical discharge within the cochlea due to fluids with different electrolyte concentrations mixing together. It is possible that some, if not many, cases are due to a decrease in blood flow to the inner ear when the inner ear hydrostatic pressure prevents normal blood flow from reaching inner ear tissues. This study enables visualization of the structures of the inner ear and brain in order to rule out tumors, strokes, multiple sclerosis, hydrocephalus, congenital anomalies, and other abnormalities which can cause dizziness and imbalance. In SSCDS, there is an erosion of the normal bone that covers the top of the superior semi-circular canal.
Ultimately, the patient and a skilled ear specialist must evaluate the history, physical examinations, entire clinical picture, and test results together in order to arrive at a diagnosis. Regular exercise, adequate rest, and control of other medical problems may be helpful as well. In this transmastoid surgical procedure, an incision is made behind the ear, and the mastoid bone is entered.
One procedure involves cutting the balance nerves (Vestibular Nerve Section) which is a neurosurgical procedure.
However, some individuals will continue to have disabling symptoms in spite of comprehensive medical therapy.
This procedure involves the use of a carbon dioxide laser, small fiberoptic telescopes, and placement of steroids or ototoxic medication through a very small opening made in the eardrum. In an outpatient surgical center setting using intravenous sedation, a local anesthetic is used to numb the ear canal and the eardrum.

Right Eardrum: Paparella Type I tube to aid in delivering additional doses of medication to the middle ear. It is performed on an outpatient basis and appears to be safe, is much less invasive than older surgical techniques, and will hopefully benefit many patients who have either failed conservative medical management or who require a more active approach to their condition.

Recent studies using imaging reinforce the concept that hydrops (measured by MRI) is correlated with both duration and hearing loss in Meniere's (Wu et al, 2015).
About 50% of people with Menieres also meet the criteria for Migraine, and for this reason, it is often a good idea to try the large repertoire of migraine treatments in persons with Meniere's disease. Remembering that nearly every linkage study done on Migraine came up with a different candidate region, we think it best to wait for more data.
Of course, this would be what one would expect in populations that have relatively little genetic heterogeneity. It has not been the author's experience that allergy and Menieres are at all closely linked. This is likely due the lack of clear definition of Meniere's disease and also the intrinsic difficulty in quantifying head injury.


Glaucoma is also another disorder in which it has been suggested there is a link to spinal fluid pressure (Nakashima et al, 2012). Some symptoms of a severe attack include vertigo (dizziness, spinning feelings), the body balance feels strange and imbalanced, feeling ill (feelings of vomiting or nausea), and even exhaustion from experiencing these symptoms for extended periods intensely. When something injures the inner workings of the ear such as concussion, falling off a bike, car accident, or anything that can shake up the inner workings of your ears.
This misbalance changes the balance of trace minerals in the fluid enough to cause vertigo, hearing loss, hot and cold spells, and other discomfort. Maintaining a regular meal plan that is consistent (including snacks) helps the body to maintain balance. Meniere's Disease may be due to vessel inflammation (vasculitis), aging and narrowing of blood vessels, and additional unrecognized factors such as problems with calcium channel metabolism, etc. Classically, two muscles are used: (1) the sternocleidomastoid muscle (cervical VEMP or cVEMP) and (2) the inferior rectus muscle of the eye (ocular VEMP or oVEMP).
The procedure is call "Laser Assisted Tympanotomy with Middle Ear Perfusion" or "LAT" for short.
Treating the inner ear with very small, strategically-placed doses of gentamicin takes advantage of this effect by inactivating the sensory cells that cause episodes of vertigo. Once the eardrum is numb, a carbon dioxide laser beam focused through a microscope is used to perform a Laser Assisted Tympanostomy (LAT) - an extremely small, bloodless opening in the eardrum approximately 2-3 mm.

Meniere's disease is one of the most common causes of dizziness originating in the inner ear. This idea is somewhat more reasonable than the idea that it is due to blockage of the endolymphatic duct, as evidence suggests that endolymph does not flow towards the endolymphatic duct in any case.
Immunotherapy for allergy, in the author's experience, is almost never a curative treatment for Meniere's disease. While it seems highly unlikely that much Meniere's disease is caused by low CSF pressure, it seems reasonable that some cases may be due to this mechanism. Foster has proposed that increase fluid pressure within the cochlea (endolymphatic hydrops) causes a decrease in blood flow to cochlear and vestibular tissues. Genetic studies are being performed at The University of Iowa, Iowa City, IA as well as several other leading research centers. Distension of the saccule of the inner ear in Meniere's Disease is what is being indirectly measured and porvides diagnostic potential.
However, it has been found to have limitations such as not completely resolving the vertigo and sometimes leading to additional hearing loss. Three study groups were evaluated, each receiving a different number of doses of gentamicin. In most cases only one ear is involved, but both ears may be affected in about 15 percent of patients. We have encountered patients with symptoms resembling Meniere's disease with maladjusted shunts for hydrocephalus.

However, there is considerable emotional pain when the disease is difficult to control, and the spells are unpredictable.
Steroids, such as prednisone, can help reduce the severity of acute attacks but have significant side effects if taken for prolonged lengths of time. The procedure usually requires an overnight stay in an outpatient surgery center and is of relatively low risk.
Overall study results showed control of vertigo in 75%, improvement in tinnitus in 48%, improvement in ear fullness in 62%, and hearing preservation in 90% of patients.
However, we do not know what causes the increase in fluid pressure within the cochlea (increased production of inner ear fluid, decreased reabsorption of the fluid, or a combination of both). A fiberoptic examination of the middle ear and round window area is then performed using delicate 1.7 mm Middle Ear Endoscopes (lighted fiberoptic tubes) attached to a miniature television camera. Again, the hearing loss may be due to patchy areas of ischemic tissue within the inner ear secondary to a lack of adequate blood flow.
The round window is located and any scar tissue, adhesions, or obstructions that may be present are carefully removed.
What Are the Causes?Although the cause is unknown, it probably results from an abnormality in the fluids of the inner ear.
The theory is that too much inner ear fluid accumulates either due to excess production or inadequate absorption. In some individuals, especially those with involvement of both ears, allergies or autoimmune disorders may play a role in producing Meniere's disease.
People with Meniere's disease have a "sick" inner ear and are more sensitive to factors, such as fatigue and stress that may influence the frequency of attacks. How is a Diagnosis Made?The physician will take a history of the frequency, duration, severity, and character of your attacks, the duration of hearing loss or whether it has been changing, and whether you have had tinnitus or fullness in either or both ears. When the history has been completed, diagnostic tests will check your hearing and balance functions.
They may include:For hearingAn audiometric examination (hearing test) typically indicates a sensory type of hearing loss in the affected ear.
Speech discrimination (the patient's ability to distinguish between words like "sit" and "fit" is often diminished in the affected ear. Since the eyes and ears work in coordination through the nervous system, measurement of eye movements can be used to test the balance system. For example, while anti-vertigo and anti-nausea medications will reduce dizziness, they may cause drowsiness. Intratympanic injections involve injecting medication through the eardrum into the middle ear space where the ear bones reside. The treatment includes either making a temporary opening in the eardrum or placing a tube in the eardrum. Gentamicin alleviates dizziness but also carries the possibility of increased hearing loss in the treated ear that may occur in some individuals. Corticosteroids do not cause worsening of hearing loss, but are less effective in alleviating the major dizzy spells.
This device is a mechanical pump that is applied to the person's ear canal for five minutes three times a day. A ventilating tube must be first inserted through the eardrum to allow the pressure produced by the Meniette to be transmitted across the round window membrane and change the pressure in the inner ear. Attacks of vertigo are controlled in one-half to two-thirds of cases, but control is not permanent in all cases. Recovery time after this procedure is short compared to the other procedures.Selective vestibular neurectomy is a procedure in which the balance nerve is cut as it leaves the inner ear and goes to the brain.
While vertigo attacks are permanently cured in a high percentage of cases, patients may continue to experience imbalance.
Labryrinthectomy and eighth nerve section are procedures in which the balance and hearing mechanism in the inner ear are destroyed on one side.
This is considered when the patient with Meniere's disease has poor hearing in the affected ear. Attacks may last for 20 minutes to two hours or longer and fatigue and an off-balance sensation may last for hours to days.
During attacks, patients may be unable to perform their usual activities, needing to lie down until the vertigo resolves.Hearing loss is often intermittent, occurring mainly at the time of the attacks of vertigo.
Usually, the hearing loss involves mainly the lower pitches, but over time this often affects tones of all pitches. Tinnitus and fullness of the ear may come and go with changes in hearing, occur during or just before attacks, or be constant.What Should I Do During an Attack?Lie flat and still and focus on an unmoving object. How Can I Reduce the Frequency of Meniere's Disease Episodes?Avoid stress and excess salt ingestion, caffeine, smoking, and alcohol.
