Inner ear infection is a medical condition caused due to the infection or the inflammation of the labyrinth or the inner ear, therefore, it is also known as labyrinthitis. From the clinical point of view, the symptoms of this disease are myriad and ranging from hearing impairment to loss of balance. Inner ear infection can be unilateral or bilateral (affecting both ears), and it is caused by bacterial or viral infection, autoimmune disease, and vascular ischemia (an impairment in the blood supply to the inner ear).
Anatomically, the inner ear or labyrinth is formed of an external bony framework, which surrounds a very thin membrane. This delicate membrane contains a meshwork of the microscopic endings of the hearing and the balance sensory organs, furthermore, these sensory organs are formed of the saccule, the utricle, the semicircular, and the cochlea. The symptoms of the inner ear infection appear when the pathogens invade the labyrinth’s membrane causing its inflammation or irritation, and eventually leading
to the destruction of the nerve endings.
The most common symptoms of the inner ear infection are; vertigo, dizziness, failure in focusing with the eyes, unilateral deafness, loss of the balance sensation, tinnitus or noises in the ear, and vomiting.
The causes of the inner ear infection (Labyrinthitis) are myriad. But there are some factors that increase the risk for this type of infection, like heavy smoking and drinking, fatigue, stresses, allergic reactions, Cholesteatoma, upper respiratory tract infection, viral diseases, and taking certain non-prescribed medications that can harm the inner ear if taken in large doses, like aspirin.
Labyrinthitis (inner ear infection) usually subsides within a few weeks, actually, most cases will be cured completely within two to three months, but there are some drugs that can effectively relief the symptoms, like antihistamines, antiemetic drugs, sedatives and drugs to reduce dizziness.
Unfortunately, there are some dangerous complications for inner ear infection, like permanent deafness and self-injury during dizziness or vertigo.
