Meniere's disease, also called idiopathic endolymphatic hydrops, is a chronic disorder of the inner ear that affects both hearing and balance. It can occur at any age, but it usually starts between young and middle-aged adulthood, and generally affects only one ear. The exact cause of Meniere's disease is unknown but it can be caused due to genetic and environmental factors. The major symptoms of the disease are repeated events of vertigo, fluctuating hearing loss and tinnitus. Hypersensitivity to sound is an important symptom that can be diagnosed by checking the loudness discomfort levels. The symptoms of this condition are often preceded by a headache, nausea, and sweating. Treatment and management of Meniere's disease requires a combination of medications, physical therapy, counseling and surgical methods, which help in relieving the symptoms and minimizing the long-term impact on life. This book covers in detail the clinico-audiological studies on Meniere's disease. It is appropriate for students seeking detailed information on this disease as well as for medical professionals.
