Malignant external otitis is an inflammatory disease that can spread to the external ear canal, surrounding tissues, and the base of skull. It is important for diabetes patients to control blood sugar and choose appropriate antibiotics. If unsuccessfully treated by conventional antibiotic treatment, it can cause complications such as facial neuropathy, mastoiditis, sigmoid sinus thrombosis, multiple cranial nerve palsy, and even death in severe cases. In case of patients have bony erosion of external auditory canal or need extensive exposure to the middle ear cavity, surgical treatment such as canal wall up mastoidectomy, or canal wall down mastoidectomy could be considered. In treating patients with malignant external otitis and otitis media, it is very significant to evaluate dura plate and sigmoid sinus through preoperative imaging such as computerized tomography and magnetic resonance imaging. We report our experience of treating the case of malignant external otitis with hypoplasia of sigmoid sinus showing the thickening of the dura membrane by inflammation.
