Free costal cartilage combined with helix stretching for correction of Tanzer IIB type constricted ear deformity

Objective To explore the effect of using free costal cartilage combined with helix stretching to correct Tanzer IIB type constricted ear deformity. Methods From January 2015 to January 2017, free costal cartilage combined with helix stretching method was performed in 8 ears of 6 patients. All patients had Tanzer IIB type constricted ear deformity. Rotation flap and subcutaneous helix tunnel were designed and prepared. Thereafter, the helix cartilage was stretched. The costal cartilage was carved and placed in the helix subcutaneous tunnel. The flap was then rotated to cover the wound. Results All patients were recovered without significant complication. No flap necrosis or cartilage exposure was observed. Helix and antihelix were obvious. The corrected ears were similar to the healthy side, after 3 to 6 months follow up. Conclusions The combination of free costal cartilage and helix stretching is an effective method to correct Tanzer ⅡB type constricted ear deformity. Key words: Congenital cup ear; Microtia; Otoplasty
