One-stage immediate reconstruction of partial auricular amputation by dog bite

Area of Science:

• Plastic and Reconstructive Surgery
• Otolaryngology
• Trauma Surgery

Background:

• Partial auricular amputation presents a reconstructive challenge, particularly when secondary to animal bites.
• Immediate reconstruction offers potential for improved aesthetic and functional outcomes.

Observation:

• A case of partial auricular amputation due to a dog bite is detailed.
• The injury involved significant loss of ear cartilage.

Findings:

• A one-stage immediate reconstruction was performed using the avulsed ear cartilage.
• The cartilage was sustained by a pedicled temporofascial flap and covered with a split-thickness skin graft.
• Perioperative antimicrobial protocols were documented.

Implications:

• This case demonstrates a viable approach for immediate ear reconstruction following traumatic amputation.
• The described technique highlights the utility of autologous cartilage and well-vascularized flaps in auricular repair.
• Effective antimicrobial strategies are crucial for preventing infection in such reconstructions.
