Abstract:
Objective To explore the clinical effect of auricle reconstruction with expanded auricle posterior flap on mastoidea and auto rib cartilage bracket for repair of congenital microtia.Methods Twenty-one eligible patients with congenital auricle malformation and defect were recruited into this study and three-stage operation was performed.A 50 ml kidney-shaped expander was implanted at mastoid process area to expand skin in stage Ⅰ surgery,followed by a regular affusion to expand skin for 3 to 4 months.The average total waterflood was (80.51 ± 3.87) ml.The volume remained stable for 1 month,once up to the predetermined amount.In stage Ⅱ surgery autogenous costal cartilage was taken and carved into inverted conch shape.Auricle was reconstructed with the expanded flap to cover the auto rib cartilage bracket.The stage Ⅲ surgery was performed for details dressing of the auricle after 3 months.Results All 21 cases underwent operation successfully.Reconstructed ear auricles were similar to uninjured sides in size and shape.Both doctors and patients were contented with the auricles.Conclusions Expanded auricle posterior flap on mastoidea can cover the auto rib cartilage bracket.Autologous costal cartilage can be carved to four layers cartilage bracket that likes an inverted conch,and followed by realistic postoperative auricular shape and strong three-dimensional sense after operation.
