Acellular dermal matrices (ADMs) have been studied extensively in the literature and have gained popularity for various reconstructive and aesthetic purposes. ADMs are composed of a basement membrane and acellular dermal layer of collagen and provide a platform for mucosal epithelization and neovascularization. Combining dermal collagen and essential growth factors allows ADMs to support adequate wound healing and bolster soft-tissue repairs. These dermal matrices can be derived from human cadaveric donor skin (allogenic) or mammalian donor sources (xenogeneic). These dermal substitutes provide the benefit of reducing or eliminating the need for autologous tissue grafts and subsequently minimize donor site morbidity. Many ADMs are currently available in the market, each with variations in processing, manufacturing, storage, preparation, and use. The literature validating ADMs in the head and neck for both cosmetic and reconstructive purposes is evolving rapidly. This review aims to provide an up-to-date and comprehensive overview of the principles of acellular dermal matrices (ADMs), the different types of ADMs, and evaluate common indications, techniques, and outcomes pertaining to select anatomic sites in the head and neck reconstruction.
