Wound Care and Management

Clinical Presentation and Treatment

Auricular perichondritis can progress to abscess formation and necrosis if untreated, typically occurring within the first month after injury, presenting as painful swelling, warmth, and redness that often spares the earlobe, according to the American Academy of Pediatrics 1
Hair removal is necessary in some cases, but clipping rather than shaving is recommended to reduce infection rates, and should be done as close to the time of surgery as possible, as supported by 2, 3
Suturing hair within a suture line should be avoided as it increases the risk of surgical site infections and can lead to poor wound healing outcomes, as recommended by 2, 3

A suture length-to-wound length ratio (SL/WL) of at least 4:1 should be used for continuous closure of incisions to reduce the risk of incisional hernia and wound complications, as recommended by the World Journal of Emergency Surgery guidelines 4
Monofilament sutures are preferred over multifilament sutures due to lower infection risk and less bacterial seeding, with a strength of evidence supported by the American College of Obstetricians and Gynecologists 4, 5
The recommended suturing technique involves using 4-0 or 5-0 slowly absorbable monofilament sutures, placing stitches 5mm from the wound edge and 5mm apart, and maintaining a suture length to wound length ratio of 4:1 or higher, with a non-locking technique preferred to avoid tissue edema and necrosis, as supported by the American College of Obstetricians and Gynecologists 6, 4, 5
Continuous suturing techniques may reduce wound dehiscence compared to interrupted sutures, as recommended by the World Journal of Emergency Surgery guidelines 6

Patients should gently clean the wound daily with mild soap and warm tap water, apply a thin layer of antibiotic ointment after cleaning (if no known allergies), and cover with a clean, dry dressing until the wound has sealed (usually 2-3 days) 7, 8
Patients should restrict to soft foods for 1 week to promote optimal wound healing, rinse with 0.12% chlorhexidine twice daily for 3 weeks to reduce the risk of infection, and practice gentle oral hygiene, as recommended by the American Academy of Periodontology 9
Increasing redness, warmth, swelling, or red streaking extending from the wound, increasing pain or tenderness beyond what would be expected, or pus or foul-smelling drainage from the wound may indicate infection, and should be treated aggressively if they occur 10
Facial sutures, including those in high-mobility areas like the chin, should be removed after 5-7 days to minimize scarring while ensuring adequate wound healing, as recommended by the American Academy of Periodontology 9
Patients should schedule follow-up appointments in 7-10 days to check healing progress and for suture removal in 5-7 days, as recommended by the American Academy of Periodontology 9, 11

Patients should protect the scar from sun exposure with sunscreen (SPF 30+) for at least 6 months to prevent darkening, after healing, and perform gentle massage of the scar with moisturizer to help with scar remodeling after complete healing (2-4 weeks), noting that scar formation continues for up to 12 months, as recommended by the American Academy of Pediatrics 11, 12
Patients should avoid strenuous physical activities for 1 week and no contact sports until complete healing (2-3 weeks) to prevent accidental trauma, as recommended by the American Academy of Pediatrics 9
Patients should avoid NSAIDs like ibuprofen if possible due to increased bleeding risk, and use acetaminophen as needed for pain according to package instructions, as recommended by the American Academy of Pediatrics 9, 11
Patients should provide additional monitoring and support during the healing process, use distraction techniques, child-appropriate explanations, and parental presence to reduce anxiety during wound care, as recommended by the American Academy of Pediatrics 11, 12
