Summary
This summary is machine-generated.

Tuberculosis mastoiditis is rare but important to consider in chronic ear infections unresponsive to antibiotics. Early diagnosis and treatment are crucial to prevent complications like facial paralysis.

Area of Science:

  • Otolaryngology
  • Infectious Diseases
  • Microbiology

Background:

  • Increasing prevalence of Mycobacterium tuberculosis, particularly in immunocompromised individuals.
  • Mycobacterium tuberculosis is a known pathogen in otitis media and mastoiditis, though rarely considered due to low incidence.
  • Chronic mastoiditis often presents without pulmonary symptoms, complicating diagnosis.

Observation:

  • Two cases of Mycobacterium tuberculosis mastoiditis are presented after prolonged, unsuccessful medical and surgical treatments.
  • Diagnosis was established following the onset of complete facial paralysis in both patients.
  • One patient had an asymptomatic pulmonary tuberculous focus; the other presented with primary mastoid disease.
  • Both patients exhibited normal immunological profiles.

Findings:

  • Delayed diagnosis of Mycobacterium tuberculosis mastoiditis can lead to severe complications, including facial nerve paralysis.
  • Tuberculous infection should be suspected in refractory cases of otitis media and mastoiditis, irrespective of host immune status.
  • Prompt antituberculous therapy is essential for favorable outcomes.

Implications:

  • Highlights the need to include tuberculosis in the differential diagnosis of chronic mastoiditis, even in immunocompetent patients.
  • Emphasizes the importance of early detection and treatment to prevent irreversible neurological damage.
  • Suggests a broader consideration of Mycobacterium tuberculosis in persistent ear infections beyond typical bacterial pathogens.
