Management of Persistent Periauricular Tag Removal Site Infection

Clinical Assessment and Diagnosis

The American Academy of Pediatrics recommends that at 2 weeks post-operatively, persistent swelling, redness, and tenderness represents a true surgical site infection rather than normal postoperative inflammation, which typically resolves within 2-3 days, in patients with auricular procedures 1, 2, 3
Auricular perichondritis is a serious complication that typically occurs within the first month after auricular procedures and presents with painful swelling, warmth, and redness that often spares the earlobe, with a diagnosis aided by acute tenderness on deflecting the auricular cartilage 1, 2
Superficial surgical site infection is characterized by purulent drainage, local pain, swelling, and erythema at the incision site, according to the Infectious Diseases Society of America 4

The American Academy of Pediatrics suggests inspecting for purulent drainage, measuring extent of erythema from wound edge, assessing for fluctuance, and testing for cartilage tenderness by deflecting the auricle, with empiric fluoroquinolone therapy (ciprofloxacin or levofloxacin) as first-line treatment for Pseudomonas aeruginosa and Staphylococcus aureus infections 1, 2, 4
If erythema extends >5 cm from the wound edge with induration, or any tissue necrosis is present, this mandates immediate antibiotic therapy, as recommended by the Infectious Diseases Society of America 4, 5
Obtaining Gram stain and culture of any purulent drainage before starting antibiotics is crucial, but should not delay treatment, according to the Clinical Infectious Diseases guidelines 4, 5

Delaying antibiotic treatment can lead to advanced infection, as early postoperative fever (first 48-72 hours) is typically non-infectious, but by day 4 and beyond, infection becomes increasingly likely, as noted by the Praxis Medical Insights 3
Using inadequate antibiotic coverage, such as standard anti-staphylococcal antibiotics alone, is insufficient for auricular infections, which require anti-pseudomonal coverage, as recommended by the American Academy of Pediatrics 1, 2

Reassessing the wound within 24-48 hours for clinical improvement is essential, as recommended by the Praxis Medical Insights 5
If symptoms persist beyond 3 weeks despite appropriate antibiotic therapy, considering imaging (CT scan) to evaluate for deeper infection or retained foreign material is necessary, according to the Periodontology 2000 guidelines 6
The ear can be repierced 6-8 weeks after complete resolution of local swelling and tenderness, as recommended by the American Academy of Pediatrics 1, 2
