Preparation of allogeneic cartilage and bone for grafting.

Seroma formation was most apparent in the A-treated groups and was probably related to the continued leakage of methyl alcohol from the graft. Warping in the pinna, fibrosis around grafts, graft resorption, and cellular infiltration were least evident in the FZ and R groups. Both produced better results than storage in BSS or A, but because radiation is far more expensive and less convenient than FZ, the latter is the better preparation and preservation technique.
