  • An infection of the connective tissue of the ear that covers the auricle or pinna
    • Typically does not involve the lobule
    • Misnomer as the cartilage is almost always involved with abscess formation and cavitation
  • May be a devastating disease if improperly treated
    • can lead to liquefying chondritis
  • Most common causes include minor trauma, burns, and ear piercing

Perichondritis of the pinna.
  • Initially presents with dull pain, progresses to severe otalgia
  • Purulent discharge
  • Erythema, swelling, tenderness of the auricle without notable fluctuance
  • No involvement of the lobule which distinguishes it from otitis externa

Differential Diagnosis

Ear Diagnoses
