Common ear diseases include otosclerosis, Meniere's disease, ear infections, tinnitus and autoimmune inner ear disease, or AIED. Ear infections are the most frequently occurring ear condition in babies and young children, notes the United States Institutes of Health's MedlinePlus.
One type of ear infection is medically referred to as "otitis media." This disease, which may be viral or bacterial in origin, affects the middle ear and causes it to become inflamed, according to Albany ENT & Allergy Services.
Tinnitus, commonly known as "ringing in the ears" occurs when there is neural damage in the inner ear. AIED develops when the body's immune system triggers an adverse immune response and erroneously attack healthy cells in the inner ear.
In the United States, an estimated 615,000 people have Meniere's disease, which can impact the vestibular system, states EarQ. Affected individuals may experience problems in maintaining proper balance. Other ear conditions include cancer, otosclerosis, cholesteatoma and perforated eardrum.
