Pediatric Dog Bite to the Face: Antibiotics, Closure, and Rabies Prophylaxis
A 6-year-old girl is brought to the emergency department 4 hours after a neighbor's dog bit her left cheek. The wound is a 2.5 cm full-thickness laceration with a punctate component, moderate contamination, and no active bleeding. The dog is a known pet with current rabies vaccination but no proof of titer. The child is up to date on tetanus. She is afebrile, and the eye exam is normal with no orbital involvement. The parents are anxious about scarring and ask whether the wound should be closed or left open, and whether she needs shots.
1. How do you manage this wound acutely, and what is your rationale for closure versus leaving it open?

Dog bites to the face are a distinct category. The face is highly vascular, which lowers infection risk and supports primary closure, and the cosmetic and psychological stakes are high. The traditional teaching to leave all bite wounds open applies mainly to hand wounds and to wounds with established infection; facial bites in a healthy child, seen within hours, are generally closed primarily after thorough irrigation and debridement.
Acute management:
- Copious irrigation with saline or dilute povidone-iodine under pressure (at least 50-100 mL per cm of wound, or roughly 250-500 mL for this wound).
- Debridement of devitalized tissue and removal of foreign material.
- Explore the wound for depth and for involvement of underlying structures (buccal mucosa, parotid duct, facial nerve). A through-and-through cheek wound needs a layered closure.
- Antibiotic prophylaxis: amoxicillin-clavulanate is the standard choice for dog bites (cover Pasteurella, Staphylococcus, Streptococcus, anaerobes). For a facial wound with primary closure, 3-5 days is reasonable; some would treat 5-7 days.
- Tetanus: up to date, so no booster needed.
- Rabies: the dog is a known pet with current vaccination, so post-exposure prophylaxis is generally not indicated, but the local health department should be consulted and the animal observed for 10 days. If the animal cannot be observed or its status is uncertain, start PEP.
Closure: layered closure with fine absorbable suture for deep tissue and monofilament for skin, with careful alignment of the vermilion and aesthetic subunits. I would close this wound primarily. I would not use a drain unless there is a dead space or significant contamination. I would see her in 48-72 hours to check for infection and again at suture removal.
2. The parents ask about scarring and whether anything can be done later. What do you tell them now, and what is your follow-up plan?

I would set expectations honestly: any full-thickness facial laceration will leave a scar, but a well-aligned closure in a child, with good wound care and sun protection, often matures well. Children heal quickly but also have high scar remodeling potential, and scars can remain red and raised for 6-12 months before fading.
Immediate counseling:
- Keep the wound clean and moist; avoid sun exposure for at least 6-12 months (sunscreen, hats).
- Silicone gel or sheeting can be started once the wound is epithelialized (typically 1-2 weeks) and used for several months; evidence supports improved scar appearance.
- Massage once healed.
- Avoid unnecessary tension on the wound.
Follow-up: wound check at 48-72 hours, suture removal at 5-7 days for facial skin (to minimize track marks), and reassessment at 4-6 weeks and 3 months. If hypertrophic scarring develops, options include intralesional corticosteroid, silicone, and possibly laser (pulsed dye) once mature. I would not promise revision; I would say that if the scar remains problematic after 12 months of maturation, scar revision (excision and reclosure, Z-plasty, or laser) can be considered, but only after the scar has matured and with the understanding that revision carries its own scar.
I would also document the discussion and involve the parents in shared decision-making, and ensure the child's pediatrician is aware.
