- Perichondritis involves infection of not only the connective tissue of the ear but typically the cartilage as well
- Symptoms include erythema, ear pain, and fevers
- The most common bacterial cause is Pseudomonas.
- Perichondritis often occurs after a wound or piercing, but trauma is not necessary for the infection to occur
- Anti-pseudomonal coverage is essential with typically oral agents for milder disease and IV antibiotics for severe infections
- Can have devastating outcomes if not treated aggressively and/or treated early due to poor blood supply to the cartilage of the ear
