Cartilage removal prior to skin grafting in the triangular fossa, antihelix, and concha of the ear. Skin grafting onto a large area of exposed ear cartilage with irregular contours poses an increased risk of inadequate re-establishment of circulation. Removal of cartilage not needed for structural support before grafting following Mohs surgery on the triangular fossa, antihelix, and concha of the ear decreases the risk of recurrence of the carcinoma, and increases the chances for survival of the graft.
