The use of acellular dermal matrix in reconstruction of complex scalp defects.

Multi-focal basal or squamous cell carcinomas of the scalp, as well as recurrent tumors or previously irradiated lesions, always require large full thickness excision to achieve successful and complete healing. Loco-regional or micro-vascular flaps are the gold standard for closure of complex defects of the scalp but in some, especially older, patients, these techniques may be contraindicated. Over the last few years, the introduction of dermal substitutes has improved wound healing and modified surgical strategies in the treatment of complex tissue loss. Matriderm s (Eurosurgical Limited, Guildford, UK) is an acellular dermal substitute constituted by a matrix of type 1 bovine collagen and elastin, with a thickness of 1 to 2mm and pores of about 75mm. Since its introduction in clinical practice, it has been used in the reconstruction of tissue following burns or complex wounds, 1,2 but few studies have focused on its use in the craniofacial region and no studies appear to have evaluated its usefulness in scalp reconstruction. Herewith, we report our personal experience using this acellular dermal matrix in a complex scalp reconstruction, comparing the esthetic outcome to that of a previous full-thickness skin graft in the same region.
