Treatment of Linear Wound on Ear Auricle

Immediate Wound Management

All auricular lacerations should be cleaned and repaired within 12 to 24 hours under local anesthesia, with simple linear tears sutured using either skin-to-skin sutures alone or combined with intercartilage sutures if cartilage is involved, as recommended by the American Academy of Pediatrics 1
Clean the wound thoroughly using sterile technique before any repair to prevent infection, particularly perichondritis which can lead to permanent cartilage deformity, according to the American Academy of Pediatrics 1
Assess the depth of the laceration to determine if cartilage is involved, as this requires additional intercartilage sutures beyond simple skin closure, as stated by the American Academy of Pediatrics 1

For simple skin-only lacerations, use skin-to-skin sutures under local anesthesia without epinephrine, as recommended by the American Academy of Pediatrics 1
For lacerations involving cartilage, combine skin sutures with intercartilage sutures to provide structural support and prevent cartilage warping, according to the American Academy of Pediatrics 1

Monitor closely for signs of perichondritis in the first month after injury, particularly during warm weather months when infection risk is highest, as advised by the American Academy of Pediatrics and Praxis Medical Insights 1, 2
Watch for painful swelling, warmth, and redness that spares the earlobe, which indicates perichondritis rather than simple skin infection, according to the American Academy of Pediatrics and Praxis Medical Insights 1, 2

If perichondritis develops, start fluoroquinolone antibiotics immediately, as recommended by the American Academy of Pediatrics and Praxis Medical Insights 1, 2
If abscess forms, surgical incision and drainage are necessary, though good cosmetic preservation becomes difficult once this occurs, according to the American Academy of Pediatrics and Praxis Medical Insights 1, 2
Acute tenderness when deflecting the auricular cartilage distinguishes deeper perichondrial infection from superficial skin infection and requires systemic antibiotics, as stated by the American Academy of Pediatrics and Praxis Medical Insights 1, 2

Never use epinephrine in local anesthesia for ear repairs, as it can compromise already tenuous blood supply, as warned by the American Academy of Pediatrics 1
Do not delay repair beyond 12-24 hours, as this increases infection risk and compromises healing, according to the American Academy of Pediatrics 1
Avoid treating suspected cartilage infections with antibiotics that don't cover Pseudomonas, as this leads to treatment failure and permanent deformity, as advised by Praxis Medical Insights 2

Re-examine within 48-72 hours to ensure no signs of developing infection, as recommended by the American Academy of Pediatrics 1
If the wound was from earring trauma and the hole has closed, the ear can be repierced in an unscarred area after approximately 3 months of complete healing, according to the American Academy of Pediatrics 1
