Meniere’s disease causes episodes of severe spinning vertigo that last anywhere from twenty minutes to several hours, alongside fluctuating hearing loss that typically affects low-frequency sounds first, tinnitus that is often low-pitched and roaring, and a sensation of fullness or pressure deep in the ear. The hearing loss comes and goes in the early stages (patients often describe “good days and bad days”), but over years it often settles into a permanent loss across more frequencies, commonly moderate to severe. The condition is unpredictable, exhausting and frequently misunderstood.
The most consistent thing about Meniere’s disease is how variable it is between people. Some have violent vertigo attacks weekly. Others go months between episodes. Some lose hearing rapidly. Others fluctuate for a decade before any permanent threshold shift shows up on audiometry. What ties them together is the triad: episodic vertigo, low-frequency sensorineural hearing loss, and tinnitus or aural fullness. When you see those three together, especially unilaterally, Meniere’s should be on your radar.
What Actually Happens to Your Hearing
Meniere’s disease is associated with endolymphatic hydrops, a build-up of fluid (endolymph) in the inner ear’s membranous labyrinth. The low-frequency region of the cochlea (roughly 250 Hz to 1000 Hz) tends to be affected first. The exact mechanism isn’t fully understood, but in the early stages the changes are at least partly reversible. After an attack, hearing often returns to baseline or near-baseline within days or weeks.
On pure tone audiometry, we see a characteristic low-frequency sensorineural hearing loss during or immediately after an attack: thresholds at 250 Hz and 500 Hz might drop to 40 to 50 dB HL while mid and high frequencies remain relatively intact. The audiogram has an upward slope, the opposite of the typical age-related or noise-induced pattern. Speech discrimination scores are often disproportionately good early on because the higher speech frequencies (1000 to 4000 Hz) are still functioning. Patients will say, “I can hear you talking, but everything sounds muffled or like I’m underwater.” That’s the low-frequency loss at work.
Over time, often years or even decades, the hearing loss stops fluctuating and becomes permanent. The audiometric configuration flattens out as mid and high frequencies are progressively affected. By the late stage, many patients have a moderate to severe flat or gently sloping sensorineural loss. The vertigo attacks often become less frequent at this point, which is a relief, but you’re left managing a significant permanent hearing impairment.
Tympanometry is typically normal (Type A), which helps rule out middle ear pathology. Acoustic reflexes may be absent or elevated, consistent with cochlear involvement. Speech-in-noise testing often shows significant difficulty even when pure tone thresholds look manageable, because cochlear damage blurs the ear’s fine frequency tuning.
Diagnosis and the Bárány Society Criteria
Meniere’s disease is diagnosed clinically, not by a single test. The diagnostic criteria published by the Bárány Society and partner organisations in 2015 require, for definite Meniere’s disease, at least two spontaneous vertigo episodes lasting 20 minutes to 12 hours, audiometrically documented low- to medium-frequency sensorineural hearing loss in the affected ear on at least one occasion before, during, or after an episode, and fluctuating aural symptoms (hearing loss, tinnitus, or fullness) in the affected ear. Other causes must be excluded.
That last part is critical. We’re not diagnosing Meniere’s disease in a vacuum. Acoustic neuroma, autoimmune inner ear disease, vestibular migraine, and superior semicircular canal dehiscence can all mimic aspects of Meniere’s. MRI with contrast is commonly used to rule out retrocochlear pathology. Blood work may be done to exclude autoimmune or metabolic causes. A thorough case history is essential: onset, duration of attacks, associated symptoms, family history.
In Australia, this typically means referral (usually through your GP) to an ENT specialist with experience in neurotology or vestibular disorders. The audiologist’s role at this stage is documentation: capturing audiometric fluctuations over time, establishing a baseline, and providing objective data to support or refute the diagnosis.
Medical and Surgical Management
Treatment is about reducing attack frequency and managing symptoms. There’s no cure. The first-line approach is conservative: a low-salt diet, limiting caffeine and alcohol, and adequate hydration. High-quality evidence for these measures is limited, but they’re low risk, and some patients find them helpful while others see no change. Betahistine is commonly prescribed in Australia, although a large placebo-controlled trial published in the BMJ in 2016 found no benefit over placebo for attack frequency. Diuretics are sometimes used with the aim of reducing fluid build-up.
For patients with frequent, disabling attacks despite dietary and medical management, intratympanic gentamicin injections are an option. Gentamicin is ototoxic and selectively damages vestibular hair cells, reducing vertigo at the cost of balance function and, sometimes, further hearing loss. It’s effective but irreversible. Intratympanic corticosteroids are a less destructive alternative, though results are variable.
Surgical options include endolymphatic sac decompression, vestibular nerve section, and labyrinthectomy. These are reserved for severe, refractory cases. Labyrinthectomy eliminates vertigo by destroying all inner ear function, so it’s only considered when hearing is already non-functional.
The Audiologist’s Role: Monitoring and Rehabilitation
Once Meniere’s is diagnosed or suspected, regular audiometric monitoring is useful, typically every six to twelve months, or sooner if you notice a change. Serial audiograms allow us to track progression, document fluctuations, and intervene with hearing aids when appropriate.
Hearing aid fitting in Meniere’s disease is not straightforward. In the fluctuating stage, amplification can be frustrating because the patient’s hearing changes week to week. Aids programmed for a 40 dB loss may be too loud when hearing improves, or insufficient when it worsens. Some patients wait until the loss stabilises. Others benefit from amplification early, particularly if speech understanding is affected or if tinnitus is intrusive. Modern hearing aids with multiple programs or adaptive features can accommodate some degree of fluctuation.
When hearing stabilises in the moderate to severe range, hearing aids become essential for communication. Real ear measurement (REM) is essential to confirm appropriate gain, especially in the low frequencies where most Meniere’s patients have lost sensitivity. Aided speech-in-noise testing helps confirm that amplification is improving function, not just making things louder.
Some patients with severe to profound unilateral loss may be candidates for CROS (Contralateral Routing of Signal) aids or, if bilateral loss is severe, cochlear implantation. Cochlear implants have been used successfully in Meniere’s patients with profound bilateral loss, though candidacy is assessed on a case-by-case basis.
What to Expect If You Have Meniere’s Disease
The uncertainty is the hardest part. You don’t know when the next attack will come, how bad it will be, or whether your hearing will recover afterward. Over time, many people identify possible triggers (stress, lack of sleep, salty meals) and develop strategies to reduce attack frequency. The vertigo typically becomes less severe as the disease progresses, but the hearing loss accumulates.
If you’re experiencing symptoms consistent with Meniere’s disease (episodic vertigo with hearing changes and tinnitus), see your GP about an ENT referral and have your hearing documented by an audiologist. Early documentation and diagnosis improve management options. If hearing in one ear drops suddenly, especially for the first time, don’t assume it’s Meniere’s: see a GP or go to an emergency department the same day or the next day, because sudden sensorineural hearing loss needs prompt treatment. Our article on vertigo and hearing loss covers the other conditions that can look similar. If you’ve already been diagnosed, regular hearing monitoring allows us to track changes and intervene when needed. At The Audiology Place, we provide baseline and serial audiometry, hearing aid fitting and follow-up, and referral coordination with ENT specialists.
Meniere’s disease is complex and individual. What works for one patient may not work for another. But with careful monitoring, appropriate medical management, and hearing rehabilitation when needed, most people find a way to manage the condition and maintain quality of life.
