Porous hydroxylapatite-perichondrium graft in cricoid reconstruction.
Composite grafts of hydroxylapatite-perichondrium were used for reconstructing defects in the cricoid of young rabbits. The alloplastic material showed no signs of resorption; it was firmly attached to the surrounding tissues by ingrowing connective tissue; only a moderate foreign body reaction was observed. The perichondrium formed new cartilage around the hydroxylapatite.
