    Abstract:
    BACKGROUND: The constricted ear is an auricular deformity produced by a deficiency in the circumference of the helical rim. The classification and corrective methods for constricted ears continue to be controversial. In order to identify them, the authors have reviewed and analyzed cases operated in a Chinese specialty clinic. METHODS: Correction of constricted ears from January of 2017 to June of 2021 was retrospect through medical records. Data of patients' variables (including sex, age, laterality, type of constricted ear, presence of other ear anomalies), surgical techniques, esthetic outcomes, and postoperative complications have been collected. RESULTS: The deformed ears were classified into four graded types by three criteria including deficiency of auricle cartilage, vertical height in dorsal view, and surgical outcome. A total of 68 constricted ears of 57 patients (type I, n = 6; type IIA, n = 41; type IIB, n = 19, and type III, n = 2) were enrolled in the study. Of the 66 constricted ears undergoing surgical correction, most of them were performed with helical expansion through auricular/costal cartilage graft, Mustardé-type mattress sutures, and tumbling cartilage flap. External molding using Vaseline gauze rolls was implemented on every case to assist reshaping the scapha. A triangular superficial temporal fascial flap was elevated to prevent the reoccurrence of lidding in some cases. Corrective techniques and esthetic outcomes for deformed cases of each graded type were described. Based on a four-point Likert scale, the average esthetic outcome score was 3.7. CONCLUSIONS: The classification was practical and the constricted ears were effectively corrected by simple surgical procedures without removal of deformed auricular cartilage. All corrections were performed in one stage. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.
