Introduction[edit | edit source]
Meniere disease (or idiopathic endolymphatic hydrops) is a disorder of the inner ear characterized by hearing loss, tinnitus, and vertigo. It is named after the French physician Prosper Ménière (1799-1862) who first recognised vertigo as an inner ear disorder.
- In most cases, it is slowly progressive and has a significant impact on the social functioning of the individual affected.
- It is an inner ear disorder and as such can affect balance and hearing.
- Primarily a unilateral disorder, however, the opposite ear can be affected in 2-50% of people diagnosed with Meniere's disease.

Epidemiology[edit | edit source]
The prevalence of Meniere disease varies between 3.5 per 100.000 and 513 per 100.000 and occurs more often in older, white and female patients.
The identification of several comorbidities which occur in an increased fashion in patients with Meniere disease gave rise to new theories about the origins of the disease.
- Migraine: Migraine occurs more often in patients diagnosed with Meniere disease although there might be an overlap between basilar migraine wrongly diagnosed as Meniere disease.
- Autoimmune Diseases: Several autoimmune diseases are associated with Meniere disease namely rheumatoid arthritis, systemic lupus erythematosus and ankylosing spondylitis
Etiology[edit | edit source]
- Current research links endolymphatic hydrops to a hearing loss of >40dB. Vertigo may or may not be associated.
- Endolymphatic hydrops is not entirely specific for Meniere disease and can be found in cases of idiopathic sensorineural hearing loss.
The exact etiology of Meniere disease remains unclear. Different theories exist, but genetic and environmental factors play a role. The relation to common comorbidities remains elusive.
- Although considered to be idiopathic, there is an association with inner ear effusions and endolymphatic hydrops.

Characteristics/Clinical Presentation[edit | edit source]
One or both ears can be affected. The chief symptoms are:
- Vertigo. This is the main symptom of Ménière's disease and is commonly the most debilitating part of an attack. This feeling of dizziness can last anywhere from 20 minutes to a few days, with the average attack being two to four hours. During an attack of vertigo, the room seems to be spinning and the person feels imbalanced. This sensation may produce nystagmus(beating of the eyes from side to side), nausea, vomiting or sweating. An attack of vertigo can persist with a constant intensity or may gradually increase in intensity. Recurrent vertigo often affects patients' daily activities even during periods of remission. The episodes often force a person to lie down for several hours and lose time from work or leisure activities. Vertigo can increase risk of falls, accidents while driving a car or operating heavy machinery.
- Hearing loss. Usually affects one ear. The person will have a decline in ability to hear during an attack but will regain hearing when current episode has ended. When a person has had Ménière's for a prolonged period, the hearing loss may become permanent. Low frequency tones are most frequently lost, but all tones may be affected as the disease progresses.
- Tinnitus i.e. sustained, loud ringing or buzzing in the ears. The intensity of this may vary, but the symptom is continual in people diagnosed with Ménière's.
- Sensation of fullness in the ears. Typically the first symptom experienced preceding an acute attack. This feeling is similar to what is felt when changing altitudes (such as in an airplane) but cannot be relieved by swallowing.
- Tullio phenomenon occasionally experienced (the precipitation of vertigo and nystagmus by a loud noise).
- Other Symptoms ; Diarrhoea; Headaches; Pain/discomfort in the abdomen; Uncontrollable Eye Movements
Evaluation[edit | edit source]
The American Academy of Otolaryngology-Head and Neck Surgery Committee on Hearing and Equilibrium set criteria for diagnosing Ménière disease, most recently revised in 1995:
- certain: a definite disease with histopathological confirmation
- definite: requires two or more definitive episodes of vertigo with a hearing loss plus tinnitus and/or aural fullness
- probable: only one definitive episode of vertigo and the other symptoms and signs
- possible: definitive vertigo with no associated hearing loss
The role of imaging is controversial, but improved spatial resolution in CT and MRI is likely to show where the endolymphatic flow is impaired.
- Some advocate patients with one-sided hearing loss should undergo magnetic resonance imaging (MRI) to rule out retrocochlear pathology.
Audiometric evaluation is mandatory in all patients with Meniere disease.
- Fluctuating low frequency unilateral sensorineural hearing loss is characteristic for the disease. The hearing loss can progress to all frequencies. Tinnitus is common and ipsilateral.
Vestibular (caloric) function testing may show a significantly under-functioning affected organ in 42% to 74% and a full loss of function in 6% to 11%
- The visual and vestibular systems interact with each other to maintain visual clarity of objects during head movement. Head movement or other stimulation of the inner ear sends signals to the muscles of the eyes via the nervous system, which is called the vestibulo-ocular reflex (VOR). The VOR normally generates eye movements that maintain clear vision with head movement. Balance tests are used to determine which ear is affected, assess the level of balance lost, and assess the brain’s compensation for the damage in the ear. See Vestibular Oculomotor Motor Screening (VOMS) Assessment
Differential Diagnosis[edit | edit source]
Other conditions can produce the same symptoms as Ménière’s disease and must be ruled out in order to develop an accurate diagnosis. The differential diagnosis is broad and includes:
- Perilymph fistula,
- Recurrent labyrinthitis,
- Migraine (bilateral hearing fluctuation),
- Congenital ear malformations,
- Multiple sclerosis,
- Posterior fossa arachnoid cysts,
- Stroke in the distribution of the anterior inferior cerebellar artery may cause symptoms similar to Ménière’s (fluctuating hearing, tinnitus, vertigo),
- Infections of the inner ear, such as syphillis and Lyme disease (episodes of vertigo and hearing loss but usually bilateral)
- Tumors, especially acoustic neuromas, of the inner ear nerve (Cranial Nerve Eight), compresses the nerve and creates hearing loss, but with no periods of improvement. Imbalance is felt more than vertigo,
- Cholesteatomas (cystic growth) or other infections of middle ear,
- Autoimmune disorder - the system producing antibodies which attack the inner ear. 
Management[edit | edit source]
Different treatment options for Meniere disease exist with substantial variability between countries. None of the treatment options cure the disease.
As many treatments have a significant impact on the functioning of surrounding structures, start with non-invasive approaches with the fewest possible side effects and proceed to more invasive steps.
- Sodium restriction diet: Low-level evidence suggests that restricting the sodium intake may help to prevent Meniere attacks.
- Betahistine (used for vertigo and Meniere's disease). It helps to reduce the episodes of vertigo associated with Meniere's disease.: A Cochrane review found low-level evidence to support the use of betahistin with substantial variability between studies. Medical therapy in many medical centers often starts with betahistine orally.
- Intratympanic steroid injections may reduce the number of vertigo attacks in patients with Meniere disease.
- Intratympanic gentamycin injections: Gentamycin has strong ablative properties towards vestibular cells. Side effects are a sensorineural hearing loss because of a certain amount of toxicity towards cochlear cells.
- Surgery with vestibular nerve section or labyrinthectomy: Nerve section is a therapeutic option in patients who failed the conservative treatment options and labyrinthectomy when surgical options failed. Labyrinthectomy leads to a complete hearing loss in the affected side
- Salt restriction helps to reduce excess fluid in ears over time. This helps to limit attacks.
- Caffeine stimulates nerves and can affect Ménière's, so a reduction in caffeine can be helpful.
- Smoking constricts the blood vessels and restricts blood flow to the nerve endings.
- Keeping stress and anxiety levels low can also help to prevent attacks. Fear of an attack could be an added stress that the person will want to learn to control.
- Hearing aids can be useful in patients with Ménière's that have progressive hearing loss. Hearing aids can help the person hear to the best of their ability for as long as possible.
Physical Therapy Management[edit | edit source]
Despite the fact that physical therapy cannot address the underlying cause of Ménière’s disease physiotherapy management can assist patients in several ways:
- Improve and help maintain adequate balance e.g. Vestibular rehabilitation (an exercise-based program, designed by a specialty-trained vestibular physical therapist, to improve balance and reduce problems related to dizziness) includes: Balance and/or leg strength/flexibility exercises; Gait training; Visual stability and training; Neck mobility and neck and arm strength techniques. The goal of treatment plan is to improve any deficits, in turn, will improve ability to function in activities of everyday living, reduce risk for falling and ultimately, improve quality of life.
- Educate patients on how to avoid injury due to imbalance or vertigo, techniques on how to fall to minimize injury
- Rehabilitate patients after destructive treatments that result in static unilateral or bilateral vestibular loss.
- Treat the “spin-offs” of Meniere’s disease (see the notes by Timothy Hain MD):
- Visual dependence for balance
- Neck stiffness caused by a common balance coping strategy
- Recognize the signs and symptoms of depression and anxiety, and make referrals when appropriate
Home Modification is often an overlooked physical therapy management tool for Meniere’s disease and other vestibular diseases. However, it is very important to the patient’s safety, especially since people with Meniere’s disease have a hard time predicting when an episode of vertigo will occur. All physical therapist who work with Meniere’s patients should be able to explain Home Safety.
To help safeguard against dangerous falls, suggest the following household improvements are suggested:
- Add grab bars to the shower or tub, both horizontal and vertical
- Add a shower or tub seat
- Add anti-slip strips in showers or tubs
- Consider an elevated toilet seat
- Add ramps and reduce threshold heights in doorways for anyone ambulating with the assistance of a wheeled device (rolling walkers, wheelchairs, scooters, etc.)
- Add handrails or secure hand holds at steps or stairs
- Place risers or blocks under the legs of couches or chairs
- Remove throw rugs throughout the house
- Clear out clutter. Set a goal to clear a pathway 36 inches wide, which leaves enough room to easily handle a walker or wheelchair
- Add light sensor night-lights in hallways and bathrooms
- Add motion-sensor alarms that alert care providers when loved ones start to get out of bed
- Carry small loads, as heavy ones throw off your balance
- Keep items you use often in easy-to-reach places
Case Reports/ Case Studies[edit | edit source]
Real Clinical Case Example of a Patient with Meniere's Disease:
An 82 year-old female patient presents with severe dizziness and ringing in the ears. She reports having frequent attacks of dizziness with an insidious onset. The patient stated that the first attack of dizziness she experienced was in November of 1968 when she was 34 years old. It was election day and as she got off the couch to go vote, she became very dizzy.
After the first attack, she had recurring attacks once every four to five years until the mid-2000's when they started to become more frequent. Her doctor gave her a medication that made her sleep, but she didn't have any other medical treatments. In 2012, the attacks became more severe causing her to seek further medical attention. Her primary care provider prescribed her Meclizine to help control the dizziness and nausea. The medication helped to control the attacks for awhile, but soon they became more severe and lasted from 48-72 hours as she developed a tolerance to Meclizine.
In 2015, she went to an Ear, Nose & Throat (ENT) doctor that specialized in hearing disorders. A CT scan and MRI were performed to rule out other pathologies and both came back negative. After a series of hearing, vision and vestibular testing, the ENT diagnosed the patient with Meniere's disease. The doctor gave her a steroid injection into the eardrum which significantly helped to manage the dizziness and tinnitus. The patient now receives yearly steroid injections and was fitted with a hearing aid to help with the hearing loss due to the disease. The patient also takes Meclizine every day as a preventative measure.
The patient has been diagnosed for two years now and has learned to self-manage the attacks. She is also better at detecting when an attack is about to happen based on the tinnitus. When the ringing in her ears turns into a rushing water sound or sounds like someone walking through mud, she knows she needs to stop what she is doing and take a break until the symptoms go away. Laying down in a dark room and listening to classical music on headphones helps to prevent a severe attack. The disease has also impacted her activities of daily living as she can no longer drive and she is very sensitive to busy backgrounds with a lot of visual input. All of this impacts her ability to go to the store and be a passenger in a car.
