Meniere’s disease is a disorder of the inner ear. The inner ear plays a crucial role in both hearing and balance, making Meniere’s a particularly challenging condition.
Diagnosing Meniere’s disease can be difficult because its symptoms overlap with other conditions. An ENT (Ear, Nose, and Throat) specialist considers the pattern of symptoms, hearing test results, and other possible causes before making a diagnosis.
What Is Meniere’s Disease?
Meniere’s disease is a chronic disorder of the inner ear, the part responsible for both hearing and balance. At the center of these functions is a complex structure called the labyrinth, which includes:
-
The bony labyrinth: A rigid outer casing that protects the delicate inner structures.
-
The membranous labyrinth: A soft, fluid-filled network suspended within the bony labyrinth.
Within the labyrinth are the key organs of hearing and balance:
-
The cochlea, which handles hearing.
-
The semicircular canals and otolithic organs (saccule and utricle), which manage balance.
Meniere’s disease is associated with an abnormal buildup of endolymph, a fluid within the membranous labyrinth. This buildup is called endolymphatic hydrops. However, the exact cause of the disease and the relationship between fluid buildup and symptoms are not fully understood.
The condition most often develops between ages 40 and 60. It usually affects one ear, although both ears may be affected in approximately 15–25% of people with the disorder.
For more information, the National Institute on Deafness and Other Communication Disorders’ guide to Meniere’s disease explains its symptoms, diagnosis, and treatment options.
Characteristics and Symptoms of Meniere’s Disease
Meniere’s disease has four main features:
-
Aural fullness: A feeling of fullness or pressure in the affected ear.
-
Fluctuating hearing loss: Hearing may improve and worsen, particularly early in the condition. Low- to mid-frequency hearing loss is a characteristic finding.
-
Tinnitus: Ringing, buzzing, or roaring sounds in the affected ear.
-
Vertigo: A sensation of spinning that typically lasts from 20 minutes to 12 hours. Nausea and vomiting may accompany an attack.
Symptoms can appear without warning, and their severity and frequency vary between people. Hearing loss may become permanent over time.
Understanding the Audiogram
When discussing fluctuating hearing loss, it helps to understand an audiogram: a chart showing the quietest sounds someone can hear at different pitches.
-
Frequency, measured in hertz (Hz), runs across the chart from lower to higher pitches.
-
Hearing level, measured in decibels (dB HL), shows how loud a sound must be before it can be heard. Larger threshold numbers indicate poorer hearing.
On a standard air-conduction audiogram, X marks generally represent the left ear and O marks the right ear.
Low-frequency hearing loss that is worse in one ear can support an assessment for Meniere’s disease. However, an audiogram alone cannot confirm the diagnosis. The ENT specialist must consider the hearing results alongside the history of vertigo and other ear symptoms.
Repeated hearing tests can help document changes over time and guide hearing support decisions.
Diagnosis
There is no single definitive test for Meniere’s disease. Diagnosis depends on the combination of symptoms, documented hearing loss, and exclusion of other explanations.
Common Diagnostic Tools
-
Hearing tests (audiometry): To identify hearing loss and track changes.
-
Medical history and symptom tracking: To review the duration and frequency of vertigo, tinnitus, hearing changes, and ear fullness.
-
Imaging: An MRI may be recommended to investigate other causes, particularly when hearing differs between ears.
-
Balance testing: May be used when needed to investigate balance problems or clarify the diagnosis.
Conditions such as vestibular migraine can produce overlapping symptoms and may need to be considered.
Specialized Tests
Electrocochleography (ECoG) and Vestibular Evoked Myogenic Potential (VEMP) testing may be used in selected cases. They can provide additional information about inner-ear function, but neither should be treated as a standalone confirmation of Meniere’s disease.
Treatment Options
There is currently no cure for Meniere’s disease, but treatment can help manage symptoms and improve daily life. The approach depends on the severity of vertigo, hearing changes, and ongoing balance difficulties.
1. Medications and Dietary Adjustments
An ENT specialist may recommend:
-
Diuretics: Sometimes prescribed to help manage fluid retention and symptoms.
-
Vestibular suppressants: Medicines such as meclizine or diazepam may be prescribed for short-term relief during vertigo attacks.
-
Antiemetics: To help control nausea and vomiting.
-
Dietary adjustments: Reducing salt intake and discussing caffeine or alcohol consumption may form part of an individual management plan.
Treatment response varies, so changes should be reviewed with the treating clinician.
2. Physical Therapy
Vestibular Rehabilitation Therapy (VRT) can help people with persistent balance problems between attacks. Exercises help the brain adapt to changes in balance signals from the inner ear.
3. Injections
-
Gentamicin injections: This antibiotic is injected into the middle ear to reduce balance function in the affected inner ear and help control vertigo. It can cause additional hearing loss, but complete hearing loss is not inevitable.
-
Steroid injections: These may reduce vertigo in some people and carry a lower risk of further hearing loss than gentamicin.
The choice depends on symptoms, remaining hearing, and the risks discussed with an ENT specialist.
4. Surgical Options
Surgery may be considered when severe vertigo continues despite other treatments.
-
Endolymphatic sac surgery: Aims to reduce pressure associated with the inner ear’s fluid system.
-
Vestibular nerve section: Cuts the nerve carrying balance information from the affected ear. It aims to control vertigo while preserving hearing, although surgical risks remain.
-
Labyrinthectomy: Removes the balance structures of the affected inner ear and causes complete hearing loss in that ear. It is generally reserved for people whose hearing is already very poor or lost.
These procedures have different effects on hearing and balance; they do not all cause profound hearing loss.
5. Hearing Support
Hearing aids may help when hearing loss affects communication. An audiologist can assess the hearing in each ear and recommend appropriate support.
If the affected ear cannot benefit sufficiently from amplification, a CROS system may be considered. It sends sound from the poorer-hearing side to the better-hearing ear. A BiCROS system also amplifies sound in the better ear when that ear has hearing loss.
These systems are options for selected hearing patterns, rather than a standard recommendation for everyone with Meniere’s disease.
Because vertigo and noticeably different hearing between ears require medical evaluation, consult an ENT specialist before selecting an OTC hearing aid. Hearing aids support hearing; they do not treat the underlying disease or vertigo attacks.
6. Tinnitus Management
-
Sound therapy: Background sounds or appropriately fitted hearing aids may make tinnitus less noticeable.
-
Cognitive Behavioral Therapy (CBT): Can help reduce the distress and emotional impact associated with persistent tinnitus.
An audiologist or other qualified clinician can help develop a suitable tinnitus management plan.
7. Other Options
The Meniett device delivers pressure pulses to the middle ear. However, evidence supporting positive-pressure therapy is uncertain, so it should not be presented as an established effective treatment.
Meniere’s disease can be challenging to live with because its symptoms are unpredictable. Understanding the condition and tracking changes can help you discuss its impact with your care team.
A tailored combination of symptom management, balance rehabilitation, and hearing support may help reduce its effect on everyday life.
If you experience recurring vertigo, tinnitus, ear fullness, or fluctuating hearing, seek evaluation from an ENT specialist to establish the cause and discuss appropriate treatment.
