What is Ménière’s disease?
Ménière’s disease describes a set of episodic symptoms including 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. Episodes typically last from 20 minutes up to 4 hours. Hearing loss is often intermittent, occurring mainly at the time of the attacks of vertigo. Loud sounds may seem distorted and cause discomfort. Usually, the hearing loss involves mainly the lower pitches, but over time this often affects tones of all pitches. After months or years of the disease, hearing loss often becomes permanent. Tinnitus and fullness of the ear may come and go with changes in hearing, occur during or just before attacks, or be constant.
Ménière’s disease is also called idiopathic endolymphatic hydrops and is one of the most common causes of dizziness originating in the inner ear. In most cases only one ear is involved, but both ears may be affected in about 15 percent of patients. Ménière’s disease typically starts between the ages of 20 and 50 years. Men and women are affected in equal numbers. Because Ménière’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 are the causes?
Although the cause is unknown, Meniere’s disease probably results from an abnormality in the volume of fluid in the inner ear. Too much fluid may accumulate 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 Ménière’s disease. In some cases, other conditions may cause symptoms similar to those of Ménière’s disease.
People with Ménière’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?
Your 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:
- An 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.
- Electrocochleography (ECoG) may indicate increased inner ear fluid pressure in some cases of Ménière’s disease.
- The auditory brain stem response (ABR), a computerized test of the hearing nerves and brain pathways, computed tomography (CT), or magnetic resonance imaging (MRI) may be needed to rule out a tumor occurring on the hearing and balance nerve. Such tumors are rare, but they can cause symptoms similar to Ménière’s disease.
What should I do during an attack of Ménière’s disease?
Lie flat and still and focus on an unmoving object. Often people fall asleep while lying down and feel better when they awaken.
How can I reduce the frequency of Ménière’s disease episodes?
Avoid stress and excess salt ingestion, caffeine, smoking, and alcohol. Get regular sleep and eat properly. Remain physically active, but avoid excessive fatigue. Consult your otolaryngologist about other treatment options.
How is Ménière’s disease treated?
Although there is no cure for Ménière’s disease, the attacks of vertigo can be controlled in nearly all cases. Treatment may include:
- A low salt diet and a diuretic (water pill)
- Anti-vertigo medications
- Intratympanic injection with either gentamicin or dexamethasone.
- An air pressure pulse generator
Your otolaryngologist will help you choose the treatment that is best for you, as each has advantages and drawbacks. In many people, careful control of salt in the diet and the use of diuretics can control symptoms satisfactorily.
