Abstract

Objective: Malignant otitis externa is a potentially life threatening infection of external auditory canal and skull base in an immunocompromised person. The outcome tends to be fatal due to the skull base osteomyelitis, especially if diagnois is delayed or is poorly treated. This epidemiological study in developing country is aimed at sensitizing for high level of suspicious early diagnosis and treatment. Method: This is a prospective study of patients with diagnosis of malignant otitis externa managed in a tertiary hospital between year 2012 - 2016. All consented patients with the disorder were enrolled into the study. Data obtained were collated and analysed. Result: Nine patients with malignant otitis externa were seen during the study period. Male to female ratio was 1:1. The peak was between 61 and 70 years. The most frequent symptoms were otalgia 9 (100%) and hearing loss 9 (100%) while cranial neuropathy was encountered in 6 (66.7%). The most implicated microganisms was Pseudomonas aeruginosa 7(28%). All patients had combination of both medical and surgical intervention. There was 1death (11.1%). Conclusion: Malignant otitis external is a complication of diabetes with high morbidity, however prompt diagnosis and treatment could mitigate the mortality
