ABSTRACT: Pediatric scalp avulsions represent a reconstructive challenge because of the unique features of scalp tissue. When microsurgical reimplantation is not feasible, alternative approaches such as skin grafting, free flap transfer with latissimus flap, or tissue expansion are considered. Generally, there is no consensus regarding management of this trauma, and, oftentimes, multiple reconstructive techniques may be needed for definitive coverage. This case study describes the reconstruction of a pediatric subtotal scalp avulsion using a dermal regeneration template and novel autologous homologous skin construct. This case was complicated by the absence of original tissue for reimplantation, excessive size of the defect relative to body habitus, and family concerns for future hair-bearing function. The reconstruction successfully provided definitive coverage and significantly reduced the size of the donor site and associated compilations. However, the hair-bearing potential of the tissue has yet to be determined.
