Malignant Otitis Externa (MOE) is a life threatening, progressive bacterial infection of the external auditory canal (EAC), mastoid and skull base. There is inflammation and damage of the bones and cartilage at the base of the skull-Osteomylitis.
Mandatory laboratory tests include an erythrocyte sedimentation rate (ESR); white and red blood cell counts, glucose and creatinine levels, and culture of ear secretions.
The ESR is typically elevated in necrotizing external otitis; therefore, it is a useful indicator of treatment response. Pathologic examination of granulation tissue removed from the external auditory canal is essential to exclude malignant processes, which may present as nonresponding inflammatory disease.
Imaging to prove the extension of infection to bony structures is generally necessary to establish the diagnosis of necrotizing external otitis. CT scanning is used to determine the location and extent of diseased tissue .The temporal bone is the first bone to be affected, with imminent involvement of the petrous apex and mastoid. Treatment often lasts for several weeks to months, because it is difficult to treat the bacteria. Strict control of diabetes mellitus is mandatory, although it can be difficult to achieve during the acute illness. Antibiotics that are effective against the microorganism are given for long periods of time. Surgery has a definite but increasingly limited role in the treatment of osteitis of the base of the skull.

StatisticsOtitis externaAcute inflammation or infection of the outer ear (pinna and ear canal) caused by prolonged exposure to wet and warm conditions.Learn More affects one in 200 Americans every year and is present in chronic form in 3-5 percent of the population. The infection spreads from the floor of the ear canal to the nearby tissues and into the bones at the base of the skull. Because of the high mortality rate (46 percent) in early series, this condition is often referred to as a€?malignant otitis externa.a€? It is also called a€?necrotizing external otitis,a€? a term that emphasizes the destructive nature of the infection.
The purpose of the culture is to look for bacteria or fungi, usually the bacteria Pseudomonas.
Imaging modalities include computed tomographic (CT) scanning, technetium and gallium scintigraphy.
Although bone sequestra and abscess are treated surgically, further extension of the operation may be counterproductive because it may expose healthy bone to the infection. Malignant otitis externa may responds to long-term treatment, but it may return in the future.
Swimmers, surfers and other individuals who are exposed to wet and warm conditions are at an increased risk.MechanismThe external auditory canal is the tubular opening between the outside environment and the eardrum (tympanic membrane).
In nearly all cases Pseudomonas aerugenosia is the causative organism, difficult-to-treat bacteria.
Osteitis of the base of the skull,a€? the most recent but less popular name for this condition.
The infection may spread more and affect the cranial nerves, brain, or other parts of the body. Excessive moisture, mechanical trauma or underlying skin conditions are contributing factors.


Eventually, these cells separate far enough for the bacteria that are normally found on the surface of the ear canal to penetrate the skin, where they find a warm environment and start to multiply.
Otitis externa is more likely to develop if the skin in the ear canal is already chafed and cracked by excessive moisture from showering or scratching.
Bacteria or fungus from the water can easily invade damaged skin.Seborrheic dermatitis, psoriasis and excessive cleaning of wax from the ears that injures the skin lining the external ear canal may increase susceptibility of the ear canal to infection. Excessive debris or cerumen may trap water in the canal.ManifestationThe chief complaint is generally itching often accompanied by pain, tenderness and swelling of the ear canal. If left untreated, the swelling can increase to include nearby lymph nodes and produce enough pain that moving the jaw becomes uncomfortable.ManagementFirst Aid Avoid getting in the water until after the problem clears up.
Use a hair dryer to carefully dry the ear after you shower (take care to ensure the air is not too hot). Examples of such medications include acetaminophen (Tylenol), ibuprofen (Advil or Motrin) or naproxen (Aleve). Refrain from putting objects — such as cotton swabs or your finger — in the ear canal or removing ear wax yourself; both actions can damage the skin, potentially increasing the risk of infection. Talk to your doctor about whether you should use alcohol-based eardrops after swimming.If you know you don't have a punctured eardrum, you can use over-the-counter eardrops or homemade preventive eardrops before and after swimming. This mixture of one part white vinegar to one part rubbing alcohol may help promote drying and prevent the growth of bacteria and fungi that can cause swimmer's ear.
