Meniere's Disease
Meniere's Disease
Definition

Causes
- Part of the labyrinth ruptures, allowing fluid in different compartments to mix
- Scar tissue causes a blockage in the labyrinth
-
Inner ear injury due to:
- Viral infection
- Syphilis , a sexually-transmitted disease
- Autoimmune disorders
- Blood vessel problems
- High cholesterol or other fats in the blood
- Hormonal disorders
- Medications, such as antibiotics and chemotherapy agents
Risk Factors
- Age: 20 to 60
- Race: Caucasian
- Family history of Meniere's disease
- Stress
- Allergies
- Excess salt in the diet
- Excess noise
Symptoms
-
Episodes of
vertigo
(spinning sensation), often accompanied by:
- Nausea or vomiting
- Sweating
- Paleness of the skin
- Weakness or falling
- In some cases, headache or diarrhea
- Hearing loss may worsen during attacks of vertigo
- Tinnitus (ringing in the ears)
- Feeling of fullness or pressure in the ear
- Poor sense of balance
- A tendency for symptoms to worsen with movement
Diagnosis
- Blood tests—to check for an underlying cause
- Hearing test —this is also called an audiometry
- Electronystagmogram—a type of eye movement test
- Auditory brainstem response—measures electrical activity in the hearing nerve and brain stem
- Electrocochleogram—measures electrical response of the inner ear to sound
- MRI scan —a test that uses magnetic waves to make pictures of structures inside the ear
Treatment
Dietary and Lifestyle Changes
- Bed-rest during acute attacks of vertigo
- Avoid foods that are high in salt and high in sugar
- Drink adequate fluids
- Promptly begin replacing fluids lost to heat or exercise
- Avoid caffeine, aspirin, and smoking
- Minimize stress
- Avoid medications that seem to bring on or worsen symptoms
- Consider a hearing aid, if necessary
- Consider masking devices (white noise) to limit the effects of tinnitus
- Take safety measures to avoid falling
- Restrict chocolate consumption
- Reduce alcohol intake
Vestibular Exercises (Vestibular Rehabilitation)
Medications
- Drugs to treat vertigo, such as meclizine or scopolamine
- Antiemetics—medications to help control nausea
-
Other medications that may improve hearing, control inner ear swelling, or limit overall symptoms, including:
- Antihistamines
- Cortisone drugs for a short time
- Antidepressants or anti-anxiety medications
- Diuretics
- Aminoglycoside therapy (such as streptomycin or gentamicin) to permanently destroy the part of the inner ear that deals with balance
Surgery
- Endolymphatic sac decompression—removal of a portion of inner ear bone and placing a tube in the inner ear to drain excess fluid
- Labyrinthectomy—destruction or removal of the entire inner ear, which controls balance and hearing
- Vestibular nerve section
Prevention
- High-salt diet
- High-sugar diet
- Excess noise
- Excess alcohol
- Stress
- Smoking
- Use of drugs that can be toxic to the ear such aminoglycosides, aspirin, and quinine
