In 10 consecutive otoplasties, conchal floor cartilage was excised to facilitate rotating prominent ears back against the head. The procedure is most effective in aural prominence due to deep conchae. Cosmetic improvement is as good as that achieved by excision of posterior wall cartilage, and recontouring of the antihelix fold is needed less often. The amount of cartilage to remove is easily determined, matching of asymmetrically prominent ears is simplified, and concha-mastoid sutures can be placed without tension. The corrections have been followed 1-2 years without recurrence of the deformity.
