A great number of surgical techniques for the correction of protruding ears have been developed. Their basic concepts originate from Mustardé's suture, the scoring technique described by Chongchet, Stenström, and Cricelair, and the combined suture and scoring technique described by Converse. Techniques for cavum rotation and lobuleplasty have also been presented. Indication, diagnostics, selection of method, the operative technique itself, and postoperative care are described. Advantages and risks of each technique are discussed, and a therapy algorithm is proposed.
