RESUMO
The augmentation of soft-tissue defects in the facial region is a challenging task for plastic and reconstructive surgeons. Numerous materials, both autologous and nonautologous materials including alloplastic implants, have been used for augmentation of soft-tissue defects of the face. Each has its limitations. There is no ideal material for soft-tissue augmentation. Acellular human dermal allograft (Alloderm, LifeCell Corporation, Woodlands, Texas, U.S.A.) combines the benefits of autografts and allografts. Alloderm does not appear to be resolved, it is a much more cost- effective treatment than fat injection, collagen injection, or other treatments that require multiple surgical operations or repeated application. Using Alloderm eliminates the need for creating a donor site. The authors report its use in 13 patients who have soft-tissue defects in the face. No serious complications such as rejection, absorption, dislocation, or extrusion were encountered. Alloderm appears to be an easily handled, safe material to use as an implant for permanent soft-tissue augmentation. Further long-term tudies are warranted to monitor the persistent volume maintenance of Alloderm.
