Aesthetic study of helix reconstruction using autologous costal cartilage

Abstract

Objective To observe the conditions of the eighth costal cartilage in ear reconstructed patients, and accomplish individualized aesthetic helix fabrication according to the texture and features of the cartilage. Methods From May 2013 to May 2016, the conditions of the eighth costal cartilages in 415 patients who received ear reconstruction with autogenous costal cartilage in our hospital were analyzed, during which, the length, width, flexibility, and plasticity that were closely related with the reconstruction of the helix attracted predominant attentions. During the surgery, based on the features of the above-mentioned aspects, 4 different methods were used to achieve reasonable length and strength of the helix as well as natural jointing between the helix and ear lobe. Results Four possible methods of using the eighth costal cartilage to reconstruct the helix were summarized and an autogenous costal cartilage framework that was individualized and with natural appearance was obtained. Conclutions According to the conditions of the eighth costal cartilage, a more satisfactory appearance of the reconstructed ear than ever before is obtained by choosing relevant helix fabrication programs.
