    Area of Science:

    • Infectious Diseases
    • Otolaryngology
    • Critical Care Medicine

    Background:

    • Malignant external otitis (MEO) is a serious Gram-negative bacterial infection.
    • It originates in the external auditory canal and predominantly affects elderly individuals with diabetes mellitus.
    • Untreated MEO can lead to severe complications, including cranial nerve palsies, sepsis, and mortality.

    Observation:

    • This study summarizes experience with 72 patients at various disease stages.
    • Key diagnostic indicators include treatment non-responsiveness, persistent suppuration, and recurrent granulation tissue formation.
    • The causative agent is consistently Pseudomonas aeruginosa.

    Findings:

    • Intravenous carbenicillin and gentamicin, coupled with hospitalization, are recommended medical treatments.

  • Minor surgical debridement can be beneficial.
  • Medical management should continue as long as improvement is observed, with surgery reserved for treatment plateaus or worsening symptoms.

    • Implications:

    • Prompt and aggressive medical management is vital for MEO patients.
    • Extended treatment (at least seven days post-cure) is necessary to prevent disease recurrence.
    • Understanding MEO's pathophysiology and treatment nuances is critical for improving patient outcomes.
