A number of surgical experiments were performed on the auricular cartilage of the rabbit in an attempt to produce a permanent smooth fold resembling the antihelix of the normal human ear. Results were evaluated grossly and histologically from the point of view of cosmesis and desirability of suture material. Surgical manipulation of the cartilage using the anterior scoring method produced the best results. Clear monofilament nylon was the most desirable suture material.
