Autogenous concha cartilage graft for correction of"lying ear"
Objective To investigate the surgical method and clinical effect of autogenous concha cartilage graft for correction of"lying ear".Methods From June 2021 to January 2023,Department of Plastic Surgery,The Affiliated Friendship Plastic Surgery Hos-pital of Nanjing Medical University performed autogenous concha cartilage graft on 12 patients with"lying ear"to correct the lying ear de-formity.In all cases,open incisions were used to fully free and loosen the subcutaneous tissue and muscle on the dorsal side of the antihe-lix.A scratch on the dorsal cartilage of the antihelix was made to release cartilage stress,and autogenous concha cartilage was grafted to the dorsal side of the antihelix to increase the cephaloauricular angle and the angle between the ear concha and the ear navicular angle.The external ear was fixed with a thermoplastic plate after the operation.The changes of cephaloauricular angle and visual analogue scale of ear shape before and after the operation were scored,and postoperative complications were recorded.Results The incision healed in 12 pa-tients.All patients were followed up for 6 months.The"lying ear"was corrected and the cephaloauricular angle angle was increased.All patients were satisfied with postoperative results and no complications occurred.The cephaloauricular angle was(26.25°±6.72°)before surgery and(40.08°±4.52°)after surgery,the difference was statistically significant(P＜0.01).Patient evaluation the VAS score of ear con-tour was(2.17±1.11)before surgery and(7.75±1.29)after surgery,the difference was statistically significant(P＜0.01).Physician evalua-tion the VAS score of ear contour was(2.82±1.25)before surgery and(7.83±0.94)after surgery,the difference was statistically significant(P＜0.01).Conclusion Autogenous concha cartilage graft for correction of"lying ear"deformity,with wear external stent after operation is a safe and effective plastic surgery method to correct the"lying ear".
