WHAT IS MENIERE’S DISEASE?
Meniere’s Disease (sometimes referred to as Meniere’s Syndrome) is an inner ear disorder which affects hearing and balance. Individuals who suffer from Meniere’s Disease also generally experience recurring episodes of dizziness, tinnitus, and progressive hearing loss. Meniere’s Disease usually affects only one ear and is caused by an increase in volume and pressure of the fluid (endolymph) in the inner ear. In 15% of patients, both ears may be affected.
WHAT ARE THE SYMPTOMS OF MENIERE’S DISEASE?
Not all individuals who suffer from Meniere’s Disease experience the same symptoms. Classic Meniere’s Disease is considered to consist of the following four symptoms:
Attacks of vertigo can be incapacitating and severe. Episodes of vertigo can last for hours, and may be accompanied by an increase in the loudness of tinnitus and a greater sense of hearing loss. Vertigo can cause nausea, vomiting and occasionally “drop attacks” which is a sudden onset of severe vertigo so severe that it causes the patient to fall. Drop attacks are a medical emergency and must be treated immediately to prevent injury to the patient and/or others.
Loss of hearing acuity can be coupled with sounds that seem distorted or unusually loud. Some individuals experience nystagmus, which is an uncontrollable jerky movement of the eye. Other individuals report short term memory loss, forgetfulness and confusion. In addition to these symptoms, other individuals report exhaustion, drowsiness, headaches, vision problems and depression.
WHAT IS THE CAUSE OF MENIERE’S DISEASE?
Meniere’s Disease is related to Endolymphatic Hydrops (excess fluid in the inner ear). As fluid pressure builds, patients experience a sense of fullness in the ear associated with increasing tinnitus. If severe enough levels of fluid pressure are reached, delicate membranes of the inner ear may rupture producing the abrupt onset of vertigo. Many causes of elevated fluid pressure exists and may include, among others, immune system related causes, otosclerosis, viral infections, chronic infections of the ear or other body systems, etc. Many cases of Meniere’s Disease are cause unknown.
HOW IS MENIERE’S DISEASE DIAGNOSED?
A Meniere’s Disease diagnosis is usually established by an individual’s medical history coupled with a detailed otoneurological examination, audiometric testing and magnetic resonance imaging (MRI). Some blood tests do show some specificity for Meniere’s Disease, though there is no conclusive blood test used for diagnosis purposes.
WHAT ARE THE TREATMENT OPTIONS FOR MENIERE’S DISEASE?
The treatment for Meniere’s Disease differs from patient to patient. At CEI, Otologists strive to diagnose the cause of the disorder and then to treat the symptoms of the disorder. This includes first the symptoms of vertigo or balance disorder followed by hearing loss and tinnitus.
In many patients, dietary modifications in the form of low salt diets plus diuretic therapy to lower inner ear fluid pressure can reduce symptoms. In others, second line therapy in the form of the Menniette Device, Intratympanic Gentamycin, or Endolymphatic Shunt Surgery are needed to control symptoms. If other methods fail, surgery to eliminate the ability of the balance nerve to send signals to the brain is needed. Hearing loss associated with Meniere’s Disease can be ameliorated through the use of hearing aids, BAHA implantation, or in the case of individuals with bilateral Meniere’s Disease, cochlear implants.
The progression of Meniere’s Disease is unpredictable. Symptoms may become more severe, remain the same, or disappear completely. Overall, over 95% of patients with Meniere’s Disease will achieve vertigo control when treated by a CEI Otologist. Treatment is very individualized and begins with a thorough work up and evaluation followed by a treatment plan.
If you suspect that you have Meniere’s Disease, or you have noticed a change in your hearing, consult your otolaryngologist. The outlook for treatment is excellent, once the diagnosis has been made and appropriate treatment is initiated.
