Auricular Perichondritis Diagnosis and Treatment

Primary Diagnostic Considerations

The American Academy of Pediatrics recommends that auricular perichondritis presents with painful swelling, warmth, and redness in the auricular area that typically spares the earlobe 1
The condition is characterized by a rash-like appearance, which is consistent with the inflammatory appearance of perichondritis 1
Acute tenderness when deflecting the auricular cartilage distinguishes this deeper perichondrial infection from superficial skin infections 1
The most common causes of auricular perichondritis are Pseudomonas aeruginosa, Staphylococcus aureus, and Streptococcus pyogenes 1
The American Academy of Otolaryngology-Head and Neck Surgery suggests that allergic contact dermatitis presents with erythema, edema, scaling, and a maculopapular or eczematous eruption on the conchal bowl and ear canal 2
Nickel is the most common contact allergen, affecting approximately 10% of women with pierced ears 2

The American Academy of Otolaryngology-Head and Neck Surgery recommends that facial nerve paralysis or paresis suggests herpes zoster oticus (Ramsay Hunt syndrome), requiring prompt systemic antiviral therapy and steroids 6
Vesicles on the external ear canal and posterior auricle indicate viral infection rather than bacterial perichondritis 6
Severe headache, meningismus, or cranial nerve deficits suggest necrotizing otitis externa or intracranial extension 7

The American Academy of Pediatrics recommends starting fluoroquinolone antibiotics immediately (ciprofloxacin or levofloxacin) to cover Pseudomonas aeruginosa and Staphylococcus aureus for suspected perichondritis 1
The American Academy of Otolaryngology-Head and Neck Surgery suggests removing the sensitizing agent (jewelry, topical medications, cosmetics) and applying topical corticosteroid or calcineurin inhibitor (tacrolimus 0.1% ointment or pimecrolimus 1% cream) for contact dermatitis 2
Topical antimicrobials are first-line, delivering concentrations 100-1000 times higher than systemic therapy for acute otitis externa 5

Delaying treatment of perichondritis leads to devastating focal cartilage necrosis and permanent ear deformities 1
Confusing perichondritis with simple otitis externa results in inadequate antibiotic coverage for Pseudomonas 1
Using topical therapy alone for perichondritis is insufficient; systemic antibiotics are required 1
