A relatively new material consisting of acellular cadaver dermis (AlloDerm; LifeCell Corporation, The Woodlands, Tex.) has become available in the past a few years for augmentation rhinoplasty that requires tip projection or correction of dorsal irregularity. Acellular dermis is originally developed for treatment of full-thickness burns for skin replacement and recently used as a soft tissue filler in facial soft tissue augmentation. When implanted within a soft tissue pocket, the intact collagen matrix structure of the acellular dermis is eventually ingrown and potentially replaced by the own tissue.
AlloDerm is a very useful soft tissue filler and its advantage is recognized by several articles. But its limitations of indication and complications have not been studied sufficiently. We experienced 7 cases of complication after rhinoplasty using AlloDerm. So we analized the complication cases and studied its limitations of indication.
