Tissue clay: an experimental model to evaluate its performance in soft tissue augmentation and its biologic fate.

ABSTRACT

Tissue clay (a mixture of autologous whole blood and microfibrillar collagen--Avitene) has been proposed as a medium for reconstruction in cosmetic and reconstructive deformities of the face. Its performance and biologic fate has not been evaluated experimentally. The current study employs a model using the rabbit pinna to determine, histologically, the fate of a tissue clay implant.
