Nonreplantable Total Scalp Avulsion Reconstruction with Acellular Biologic Matrix and Long-Term Outcome

Total scalp avulsion is a significant injury typically occurring as a result of industrial accidents involving high-speed rotary machines. Although ideal, scalp replantation is uncommon secondary to the nature of the injury and lack of viable microvas-cular anastomosis targets. Therefore, these defects are often reconstructed with microvascular free tissue transfer, with or without skin grafting. We present a unique case of a patient with total scalp avulsion achieving complete, stable skin coverage over partially intact periosteum using only spare parts of the amputated scalp as a temporary full-thickness graft and porcine urinary bladder matrix, thus, avoiding significant donor site morbidity or extensive surgery. At 4 years postoperative, the scalp coverage remains stable.
