    Basics

    Description

    Inflammation and/or infection of the pinna

    Etiology

    • Mechanism:
      • Cartilage of the external ear is easily damaged due to:
        • Lack of overlying subcutaneous tissue
        • Relative avascularity
        • Exposed position
      • Chondritis:
        • Most commonly a secondary complication of otic trauma and burns
        • Onset is often insidious and may be delayed until apparent healing has occurred.
    • Improper management may cause disfiguration of the pinna secondary to cartilage avascular necrosis:
      • Ranges from being a shriveled, cauliflower-like ear to complete loss of the external ear and possible stenosis of the auditory meatus.
    • Causes:
      • Common causes of chondritis include:
        • Chemical or thermal burns
        • Frostbite
        • Hematoma formation
        • Trauma
        • Human/insect bites
        • Deep abrasions
        • External otitis
        • High piercing of the ear lobe especially with poor technique, hygiene, and aftercare.
      • Bacteria involved:
        • Pseudomonas aeruginosa
        • Staphylococcus
        • Proteus
