Overview

CT imaging is essential in establishing a diagnosis of malignant necrotizing otitis externa by revealing the extent of infection past the ear canal and spread into temporal and intracranial bones. They reveal the extent of damage and inflammation of the bones and soft tissue, demonstrating the cause for facial palsy due to the inflammatory influence on the cranial nerves.

Key CT Findings in Otitis Externa

  • CT Imaging of malignant necrotizing otitis externa is essential in facilitating diagnosis by proving the extension of infection into the temporal or intracranial bones.[1]
  • Key CT findings in cases of malignant otitis externa include the following:[2]
