The cartilage perforator was devised to make holes through cartilage implants. It consists of a punch in which the upper jaw is fenestrated and the lower one contains a riveted pin which penetrates the cartilage. The shanks have a spring action which readily opens and closes the instrument.
The cartilage is not fractured when the holes are produced. The punctures permit better anchorage in the recipient area. They also allow fibroblasts to penetrate the holes for eventual fixation. The perforator is especially useful for bovine and septal cartilage implants. Cartilage perforator
