Preliminary report on the comparative use of lyophilized homograft and xenograft in the closure of raw areas

Abstract

Abstract Lyophilized allograft and xenograft appear to be equally effective for the temporary cover of raw areas1. Lyophilized allograft has the disadvantage of occasionally separating into two layers when removed. One layer can easily be missed and inhibit the take of a subsequent autograft. Lyophilized xenograft is easier to handle and more easily available. In spite of the many advantages shown to be associated with this method of treatment, it is still virtually unused in Great Britain and in many other parts of the world.
