[Vascularization and resorption of different supporting tissues by the greater omentum in the formation of compound microvascular transplants].

In former investigations the author described the use of omentum majus in building microsurgical compound island flaps employing supporting tissue. Now different kinds of hard tissue, such as autogenous bone and cartilage, allogenous bone and cartilage (preserved by Cialit-solution), Teflon-Fluorocarbon Polymer (Proplast) and tri-calcium phosphate were presented in omentum-sandwich flaps in a histological investigation. We paid special attention to resorption and vascularisation of hard tissue. Allogenous cartilage grafts or artificial materials like Proplast were the most suitable to put into a compound omental island flap. There was good vascularisation with no resorption, especially with Proplast.
