Episodic vertigo is the most common reason for patients to seek and pursue treatment for Meniere’s disease.
If episodes of vertigo persist despite changes in diet, medication called diuretics can be helpful.
Other options are available and include transtympanic decadron or gentamicin, decadron perfusion of the inner ear, endolymphatic sac surgery, vestibular neurectomy and labyrinthectomy surgery.
Steroid treatment of the inner ear may offer beneficial effects for the symptoms of Meniere’s disease. A powerful way of delivering steroid to the inner ear is by injection into the middle ear through the tympanic membrane. There is a 1% chance of a persistent 1 mm perforation of the eardrum at the injection site. This form of treatment involves injection of medication through the eardrum into the middle ear.
A shunt is placed in the endolymphatic sac, a reservoir for endolymph, to shuttle fluid out of the sac and into a cavity created in the mastoid. Step 3: A mastoidectomy is done exposing the semicircular canals, venous sinus, and dura covering the brain. Step 4: Spinal fluid is drained and the brain relaxes, exposing the trigeminal nerve (responsible for the conduction of facial sensation), the vestibulocohlear nerve (hearing and balance), and the facial nerve. This is an operation to divide the balance nerves and interrupt the connection between the inner ear and the brain. The middle fossa approach is the least commonly used and involves an incision above the ear followed by removal of bone over the brain. Another approach is the retrolabyrinthine approach, which involves incisions behind the ear similar to the endolymphatic shunt procedure. A third approach is the suboccipital approach, which involves an incision further behind the ear and removal of bone over the covering of the brain.

Also referred to as noise-induced hearing loss, sensorineural hearing loss is caused by damaged or destroyed hair cells in the inner ear that no longer transfer sound information to the brain. Sensorineural hearing loss can rarely be corrected medically or surgically, so hearing aids are the primary solution. Since sensorineural hearing loss is typically caused by exposure to loud noises, we highly recommend the use of ear protection if you find yourself around loud noises frequently. If you have any questions about sensorineural hearing loss or hearing loss in general, please contact one of our locations to speak with an audiologist. The results of a patient's hearing screening are illustrated on a graph called an audiogram.
An audiogram indicates how much hearing varies from normal and, if there is a hearing loss, where the problem might be located in the hearing pathway.
Frequency or pitch of sound is measured along the horizontal axis of the graph in Hertz (Hz), from 125Hz to 8,000Hz.
Normal, young, healthy human ears can hear frequencies as low as 20Hz and as high as 20,000Hz. Loudness or level of sounds is measured along the vertical axis of the audiogram in decibels (dB).
The audiogram shows how loud a sound has to be for the patient to hear it at a particular frequency. Air conduction thresholds for the right ear (that is, the softest sounds the right ear can hear at each frequency) are marked as an 'O' and the left as an 'X' on the audiogram. Bone conduction thresholds are marked on the audiogram as (better ear), [(right ear) or] (left ear). In the example above, the patient can't hear high pitched sounds as well as the low pitched sounds. If the hearing thresholds obtained by bone conduction are the same as the air thresholds, this indicates no blockage in the outer or middle ear. A sensorineural hearing loss can be caused by exposure to excessive noise, or by the ageing process.


There is rarely any medical treatment for sensorineural hearing losses and so the impairment is permanent.
If the bone conduction hearing thresholds are normal, but there is a loss of hearing for air conduction sounds, this is called a conductive hearing loss. This means that the cochlea is normal, but there is some blockage to sound in the middle or outer ears. It is possible to have both a sensorineural and a conductive hearing loss - for example, if a person has a noise caused impairment and a perforated ear drum. The degree of hearing loss essentially describes the degree of impact on a person's everyday life.

Administration of steroids to the inner ear is an attempt to reduce the inflammation within the inner ear. From here, the steroid diffuses through the round window (one of the two openings into the cochlea of the inner ear)membrane and enters the inner ear. The medication, which is then taken up by the inner ear, destroys the hair cells of the inner ear.
Of the surgical options, this is the most conservative operation with minimal risk to hearing. The mastoid bone is entered and the endolymphatic sac is decompressed, meaning that the bony covering is removed. The ear may protrude slightly shortly after surgery, but it should return to its original position in two to three weeks. 90-95 percent of patients who undergo this operation for Meniere’s disease will not have another spell of vertigo.
The roof of the canal through which the balance nerves run is removed and the nerves are then divided. Nearly all patients with Meniere's disease will be vertigo-free after a labyrinthectomy. Using a high-powered drill, the mastoid bone is entered and the semicircular canals are removed. Sanjay Prasad MD FACS is a board certified physician and surgeon with over twenty years of sub-specialty experience in Otology, Neurotology, advanced head and neck oncologic surgery, and cranial base surgery. Hearing loss of this sort is often caused by prolonged exposure to very loud noise, though auditory pathways (or hair cells that transfer sound) in the brain are sometimes abnormal at birth, resulting in some level of hearing loss. Correctly fitted hearing aids amplify tones based on an individual’s unique sound deficiencies.
For example, 250 Hz sounds like middle C on the piano, while the high pitched ringing of the telephone is about 3,000Hz.
However we only test hearing in the range of 250Hz to 8,000Hz, as most sounds of speech occur in this frequency range. Conversational voice level is around 65dB, and 120dB is very loud - about as loud as a jet taking off if you are standing 100 metres away.
You can see this by looking at the sloping line on the graph: as the frequency increases the required sound level also increases before the patient can hear it. Middle ear conditions caused by these blockages can often be corrected by medical or surgical treatment.

During the procedure, the eardrum is elevated and the round window (one of the two openings into the cochlea of the inner ear) membrane is perfused with high-dose steroid. The medication, Gentamicin, is an antibiotic that is toxic to the hair cells of the hearing and balance organ. Unfortunately, control of vertigo occurs in only 60 percent of patients undergoing this operation.


After the operation, disequilibrium lasts until the brain learns to compensate and adapt to the lack of input from one inner ear. He is chief surgeon and founder of the private practice, Metropolitan NeuroEar Group, located in the metropolitan Washington D.C.
Typically, sensorineural hearing loss reduces the ability to hear faint sounds or causes speech to sound faint or muffled, which results in the need for sound amplification.
In most cases, total communication is greatly improved through the addition of hearing aids. Further, the accuracy, currency and completeness of the information available on this Web site cannot be guaranteed. This is a relatively painless procedure that involves anesthetizing the tympanic membrane and then injecting the steroid thereafter. The fluid that would normally enter the sac is shunted away from the inner ear and into the cavity created by the surgery, where it is then reabsorbed.
This is an operation that is recommended to patients who have no useful hearing in the dysfunctional ear.

Avoiding adding salt to meals and curtailing intake of snacks high in sodium, including canned foods and fried foods, can be helpful. Just as in vestibular neurectomy, after the operation, disequilibrium lasts until the brain learns to compensate and adapt to the lack of input from one inner ear. These electrodes detect contractions of the facial muscles, and the signals are transmitted to a speaker so the surgeon may hear the responses.
When inner ear nerves become damaged and do not properly transmit their signals to the brain. Sensorineural hearing loss not only reduces the intensity of sound, but it might also introduce an element of distortion resulting in sounds being unclear even when they are loud enough.
Hearing aids can help treat the symptoms of sensorineural hearing loss, however they cannot perfectly reverse symptoms like eyeglasses do.Degree of Hearing LossDegree of hearing loss refers to the severity of the loss. The person may start to find it difficult to hear and understand people when in a noisy place.
These hair cells change the sound waves into electrical impulses that travel along the auditory (hearing) nerve to the brain. It usually happens because the Chemotherapy drug has been absorbed into the fluid that surrounds the hair cells.
Swelling or a tumor pressing on the nerve can keep the nerve from working properly.Age-related hearing loss (presbycusis) The aging process is a very common cause of sensorineural hearing loss. Depending on the level of hearing loss and the pitches that are affected, the audiologist may suggest that the patient try hearing aids. Unfortunately,  hearing aids are not like glasses, in the sense, they will not give a patient normal hearing. Hearing aids may help make some sounds easier to hear that they may not have heard well before.
With hearing aids, speech may still sound distorted to the patient, because hearing loss affects the inner ear in different ways. Making sound loud enough for a patient to hear does not always make sound easier to understand.The goal of any treatment is to improve your hearing.
