It occurs primarily in immunocompromised.. Malignant external otitis (MEO) is an infection that affects the external auditory canal and temporal bone. The causative organism is usually Pseudomonas aeruginosa, and the disease commonly manifests in elderly patients with diabetes. The infection begins as an external otitis that progresses into an osteomyelitis of the temporal bone
Necrotizing (malignant) otitis externa (NOE) is a spreading necrotizing infection of the external auditory canal (EAC) soft tissue that can produce an osteomyelitis of the entire skull base.

Abstract. Introduction: Malignant or necrotizing otitis externa (NOE) is an invasive infection of the external ear canal that primarily affects elderly diabetic or immunocompromised patients. The role of hyperbaric oxygen therapy (HBO) in NOE management is not well established but some authors believe that HBO is a valuable and beneficial treatment method and recommend its use in NOE for. Malignant external otitis is a severe infection of the external auditoy canal, characterized by high gravity and mortality. It can arrive to skull base and originate intracranial complications. The most frequent pathogenic agent is Pseudomonas aeruginosa. Authors described two cases of external malignant otitis caused by Staphylococcus aureus. Malignancy (from Latin male 'badly', and -gnus 'born') is the tendency of a medical condition to become progressively worse.. Malignancy is most familiar as a characterization of cancer.A malignant tumor contrasts with a non-cancerous benign tumor in that a malignancy is not self-limited in its growth, is capable of invading into adjacent tissues, and may be capable of spreading to distant. Fifty-five patients hospitalized for osteomyelitis of the temporal bone between 1990 and 2011 were divided into two study groups: group 1 was patients collected from 1990 to 2001 and group 2 was composed of patients between 2002 and 2011. Clinical diagnostic criteria and epidemiologic data were analyzed to illustrate the altering features of osteomyelitis of the temporal bone Start studying Disorders of the Mouth & Throat, Ophthalmology 1, Ophthalmology II, Disorders of the Nose & Sinuses, Disorders of Head and Neck, Disorders of the Ear.
