AlloDerm for dorsal nasal irregularities

After nasal surgery, thinning of the nasal skin, bony irregularities, or ad hesions of dorsal skin to underlying bone can all occur. These problems can be solved by using either alloplastic materials or various autogenous tiss ues. In this study, AlloDerm, a dermal replacement derived from cadaveric s kin, has been used to cover the osseocartilaginous framework of the nose in an attempt to achieve a smooth contour and a natural feel in secondary rhi noplasties. Fifteen patients were treated and observed for a minimum of 24 months. Clinically palpable or visible bony irregularities were successfull y covered, and adhesions of dorsal skin to nasal bones were diminished. Pro longed but not socially unacceptable dorsal nasal swelling, which resolved during the first 4 months, seemed to be the only problem related to its use . With this limited experience, AlloDerm was found to be useful in secondar y nasal surgery to cover osseocartilaginous irregularities, to eliminate th e adhesions between nasal bones and overlying skin, and to create a smooth nasal dorsum.
