Chronic suppurative otitis media
- Persistent drainage from middle ear through perforated tympanic membrane lasting > 6 weeks
  - Perforated tympanic membrane usually heals within weeks
  - No healing -> sign of chronic inflammation
- Older children
- Bacteria enter through perforated TM
- Clinical features
  - 3 yes 1 no
  - Yes: Perforation of TM
  - Yes: Ear discharge
  - Yes: Conductive hearing loss
  - No: No pain
- Two types
  - Mesotympanic
    - Central perforation
    - Treatment: tympanoplasty
  - With cholesteatoma
    - Cholesteatoma: keratinizing squamous epithelium found in bony spaces, and the bone is destroyed by inflammatory osteoclastic process
      - In TM, auditory canal or mastoid
    - Can become infected
    - Marginal perforation
    - Brown irregular mass
    - Imaging to assess bone destruction
    - Treatment: surgery
