Salvage of a nasal chondrocutaneous flap after a traumatic avulsion injury using a combination of treatments polydeoxyribonucleotide injection, continuous non-rebreather mask oxygen therapy, and chemical leeching: a case report

Abstract

Skin avulsions are severe traumatic injuries, in which sections of skin and subcutaneous tissue are torn off from the body, and the surgical management and salvage of these injuries are quite challenging due to their high morbidity and mortality. The entire or partial loss of an avulsed flap is prone to occur. If this happens, scars can be particularly conspicuous, and additional surgery, such as skin grafts or local flaps or even composite grafts, might be required. A 24-year-old male patient presented to the emergency room with a severe traumatic avulsion injury on his nose. We used a combination of three therapies to minimize the loss of the distal portion of the avulsed flap: polydeoxyribonucleotide injection, continuous non-rebreather mask oxygen therapy, and chemical leeching. We achieved complete flap salvage of the avulsed wound, and the patient showed full satisfaction in both aesthetic and functional aspects. Although this report is confined to a single case of severe avulsed injury, we suggest this triple-combination therapy as a good combined modality for maximizing the salvage of an avulsed flap on the basis of this case and a literature review.
