Malignant external otitis, a severe diabetic infection, spreads through bone erosion and into adjacent tissues. Computed tomography is crucial for diagnosing and managing this Pseudomonas aeruginosa-caused condition.

Area of Science:

  • Infectious Diseases
  • Radiology
  • Otolaryngology

Background:

  • Malignant external otitis (MEO) is a severe necrotizing infection of the external auditory canal.
  • Predominantly affects diabetic patients and is typically caused by Pseudomonas aeruginosa.

Observation:

  • MEO can spread via bony erosion to the mastoid bone.
  • Anterior spread involves the parotid gland and temporomandibular joint.
  • Inferior spread affects the infratemporal fossa soft tissues.

Findings:

  • This study presents four cases of MEO.
  • Illustrates typical patterns of disease spread.
  • Highlights the diagnostic and management role of radiology, especially computed tomography (CT).

Implications:

  • Early and accurate diagnosis via CT is vital for effective MEO management.
  • Understanding spread patterns aids in treatment planning.
  • Radiological imaging is essential for assessing the extent of MEO.
