If treated appropriately, hearing loss related to otitis media can be alleviated. When left undiagnosed and untreated, otitis media can lead to infection of the mastoid bone behind the ear, a ruptured ear drum, and hearing loss. This condition can occur in one or both ears and primarily affects children due to the shape of the young Eustachian tube (and is the most frequent diagnosis for children visiting a physician). The most common cause of hearing loss in children is otitis media, the medical term for a middle ear infection or inflammation of the middle ear. If you suspect that you or your loved one has a problem with their hearing, ensure optimal hearing healthcare by seeking a medical diagnosis from a physician. If left undiagnosed and untreated, some conditions can lead to irreversible hearing impairment or deafness. Treatment of these and other hearing losses can often lead to improved or restored hearing. Many medical conditions, such as those listed below, can affect your hearing health.

The inner ear is also capable of producing an autoimmune response to sensitized cells that can enter the cochlea through the circulatory system.Ī multi-institutional clinical study, Otolaryngology Clinical Trial Cooperative Group (OCTCG) co-sponsored by the NIH and the American Academy of Otolaryngology-Head and Neck Surgery Foundation, is being conducted to measure the benefits and risks of treating AIED with two different immunosuppressive drugs: prednisone and methotrexate, a chemotherapy drug. Studies have shown that the perisacular tissue surrounding the endolymphatic sac contains the necessary components for an immunological reaction.
Until recently it was thought that the inner ear could not be attacked by the immune system. If patients are unresponsive to drug therapy and hearing loss persists, a cochlear implant maybe considered. Some patients may benefit from the use of hearing aids. Most patients with AIED respond to the initial treatment of steroids, prednisone, and methotrexate, a chemotherapy agent. One diagnostic test that is promising is the Western blot immunoassay.
Diagnosis of AIED is difficult and is often mistaken for otitis media until the patient develops a loss in the second ear. In addition, a ringing, hissing, or roaring sound in the ear may be experienced. Patients may feel fullness in the ear and experience vertigo. The hearing loss can progress over weeks or months. The symptoms of AIED are sudden hearing loss in one ear progressing rapidly to the second ear. Here, the vibrations become nerve impulses and go directly to the brain, which interprets the impulses as sound (music, voice, a car horn, etc.). The vibrations are passed to the small bones of the middle ear, which transmit them to the hearing nerve in the inner ear.
These funnel through the ear opening, down the ear, canal, and strike your eardrum, causing it to vibrate. The inner ear contains the auditory (hearing) nerve, which leads to the brain.Īny source of sound sends vibrations or sound waves into the air. Small bones in the middle ear help transfer sound to the inner ear. The eardrum separates the ear canal from the middle ear. The outer ear (the part you can see) opens into the ear canal. The ear has three main parts: the outer, middle and inner ear. AIED is a rare disease occurring in less than one percent of the 28 million Americans with a hearing loss. It occurs when the body’s immune system attacks cells in the inner ear that are mistaken for a virus or bacteria. Autoimmune inner ear disease (AIED) is an inflammatory condition of the inner ear.
