We present a case of malignant external otitis (MEO) in a diabetic patient.
He had received three operations for debridement, but the lesion could not be eradicated because of extensive infection of the temporal bone, and the adjacent areas such as the left parotid gland and external surface of the skull base. He also received a long-term administration of antibiotics, but he died of sepsis 13 months after the onset.
Recently, treatment outcome of MEO has been improved. In the literature, surgical excision of the lesion and a long-term treatment of antibiotics are standard treatment of MEO. We thought that insufficient surgical debridement due to the involvement of inaccessible region was the major cause of incurability of his illness.
