Summary:Malignant otitis externa is an inflammatory condition of the external ear which has the propensity to spread to the skull base. It can be a difficult entity to treat as clinical presentation varies and response to treatment differs between patients. We reviewed cases of malignant otitis externa in our setup to document the epidemiology and outcome of management. This is a retrospective case review observational study from January 2013–December 2017. Fourteen patients diagnosed with malignant otitis externa in our tertiary referral centre were included in the study. Based on hospital protocol, empiric treatment was started. After discharge, the patients follow up visits to the hospital were also documented. Otalgia was the most common symptom. Edema and congestion of the external auditory canal were observed in most cases. Diabetes was present in all patients. Three cases had associated facial palsy, and one patient had involvement of 7th, 9th, 10th, 11th and 12th cranial nerve. Two patients with facial palsy recovered. Pseudomonas aeuroginosa was the most common organism isolated (50%). In our series, malignant otitis externa invariably presented with severe otalgia. Lower cranial palsies were also seen. Methods to evaluate complete eradication of disease should be centered on clinical symptoms and signs, but the measurement of erythrocyte sedimentation rate or radiological imaging may be used as a useful adjunct when there is uncertainty.
