  • 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
