The condition is classified according to whether it occurs suddenly and for a short time (acute) or repeatedly over a long period of time (chronic).Specific types of ear infection include:Otitis externa - acuteOtitis externa - chronicOtitis externa - malignantOtitis media - acuteOtitis media -chronicOtitis media - with effusionSymptomsSymptoms may include:ChillsDiarrheaDrainage from the earEaracheEar noise or buzzingFeverHearing lossItching or other discomfort in the ear or ear canalIrritabilityMalaise(feeling of general illness)NauseaVomitingSigns and testsYour health care provider will examine your ears and use an instrument called an otoscope to look inside them.

It is an uncommon complication of both acute swimmer's ear and chronic swimmer's ear.Risks for this condition include:ChemotherapyDiabetesWeakened immune systemExternal otitis is often caused by difficult-to-treat bacteria such as pseudomonas. The infection spreads from the floor of the ear canal to the nearby tissues and into the bones at the base of the skull. The infection and inflammation may damage or destroy the bones. The infection may spread more and affect the cranial nerves, brain, or other parts of the body.SymptomsDrainage from the ear - yellow, yellow-green, foul smelling, persistentEar pain - felt deep inside the ear and may get worse when moving headHearing lossItching of the ear or ear canalFeverSigns and testsA doctor will look into your ear for signs of an outer ear infection (otitis externa). The head around and behind the ear may be tender to touch. A nervous system (neurological) examination may show that the cranial nerves are affected.If there is any drainage, the doctor may send it to the lab for a culture. The purpose of the culture is to look for bacteria or fungi, usually the bacteria Pseudomonas.To look for signs of a bone infection next to the ear canal, the following tests may be performed:CT scan of the headMRI scan of the headRadionuclide scanTreatmentThe goal of treatment is to cure the infection. Treatment often lasts for several months, because it is difficult to treat the bacteria and reach an infection in bone tissue.Antibiotics that are effective against the microorganism are given for long periods of time. They may be given through a vein (intravenously), or by mouth. Antibiotics should be continued until scans or other tests show that inflammation has gone down.Occasionally, surgery to remove dead or damaged tissue (surgical debridement) in the skull is needed.Expectations (prognosis)Malignant otitis externa usually responds to long-term treatment, but it may return in the future.ComplicationsDamage to the cranial nerves, skull, or brainReturn of infection, even after treatmentSpread of infection to the brain or other parts of the bodyCalling your health care providerCall for an appointment with your health care provider if:You develop symptoms of malignant otitis externaSymptoms continue despite treatmentYou develop new symptomsGo to the emergency room or call the local emergency number (such as 911) if you have:ConvulsionsDecreased consciousnessSevere confusionPreventionTo prevent an external ear infection:Dry the ear thoroughly after it gets wet.Avoid swimming in polluted water.Protect the ear canal with cotton or lamb's wool while applying hair spray or hair dye (if you are prone to getting external ear infections).After swimming, place 1 or 2 drops of a mixture of 50% alcohol and 50% vinegar in each ear to help dry the ear and prevent infection.Treat acute otitis externa completely.
