RESUMEN
Objective@#To investigate the effect and safety of ultra-thin oblique posterosuperior auricular fascial flap in the second stage of ear reconstruction.@*Methods@#Fifty-six cases with congenital microtia treated in The Second Affiliated Hospital of Zhengzhou University Medical Cosmetology Department from November 2015 to November 2018 were selected as the research objects. In the first stage, the costal cartilage ear stent was implanted, and in the second stage. The ultra-thin posterior oblique fascia flap was used to cover the stent. And the cranioauricular angle was reconstructed by free skin grafting.@*Results@#48 cases of the 54 cases completely survived, and 8 cases had hemorrhage after operation. The wounds were healed after dressing change. The postoperative cranioauricular angle was close to the healthy side.@*Conclusions@#In the second stage of ear reconstruction, the retroauricular ultra-thin fascial flap method has reliable blood supply, small wound, unswollen reconstructed ears, and good outcome. It is a good choice for covering the ear framework.
RESUMEN
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.
RESUMEN
Objective To study a simple, safe and effective way in correction of prominent mandibular angle. Methods Curved osteotomy was employed for prominent mandibular angle through intra and extra oral approach with a small incision in 20 cases.Partial masseter resection was performed simutaneously in 5 cases with masseter hypertrophy, buccal fat pads were resected in 3 cases with broad faces, and genioplasty were performed in 3 cases with micrognathia. Nine cases only suffering from prominent mandibular angle were underwent curved osteotomy reconstruction. Results A series of 20 cases was followed up from six months to six years, in which 95 % was satisfactory.Conclusion The advantages of this method are simple, safe and symmetric with better result. It is easy to dissect under periosteum and perform curved osteotomy with less complication, quick recovery, and better contouring.
