Clinical and histological late findings on pedicled skin flaps in the oral cavity.

Pedicled skin flaps of 22 patients which had been exposed for many years to the environment of the oral cavity were examined clinically and histologically. The results permit statements to be made on the nature of the changes which occur on the surface, and in the histological picture of the graft. The superficial skin changes, as well as the typical histological structures of the external skin are shown in the micro-photographs presented, to be still preserved after many years.
