RESUMO
Objective@#To investigate the treatment of protrusion deformity of the concha cavity with cartilage excision and turning over of the concha cavity, and to evaluate its advantages, disadvantages and indications.@*Methods@#Eight patients with protrusion deformity of the concha cavity were treated by this method in Wuhan Union Hospital from January 2010 to January 2018.An incision was made in the auriculocephalic angle to expose the dorsal side of the anterior concha cartilage. An elliptical incision was made on the edge of the protrusion area of concha cavity and stripped. The cartilage slices were turned over after crossing scratches and re-implanted into the corresponding area of the concha cavity and sutured with absorbable suture. Then packing with a gauze ball in front of the concha cavity. To observe the healing of incision and the occurrence of hematoma 10 days postoperative. The skin shrinkage of concha cavity and the secondary deformity of concha cavity were evaluated 6-12 months later when the patients were followed-up.@*Results@#The protrusion deformity of concha cavity was corrected in all patients. The incision healed well without local hematoma. There was no obvious distortion of the concha cavity after 6-12 months follow-up.@*Conclusions@#Harvesting and in situ turning over of cartilage slices can effectively treat the protrusion deformity of the concha cavity. There is no skin shrinkage and deformation in the concha cavity after operation.
RESUMO
Objective@#To investigate the curative effect of auricular deformity repaired by concha cartilage.@*Methods@#From January 2017 to June 2018, 15 cases with auricular deformities were repaired using the autologous concha cartilage which combined with the retroauricular flap or retroauricular fascia with skin grafting. 9 males and 6 females, aged 10-40 with an average age of 19; 3 cases of upper 1/3 traumatic auricle defect, 2 cases of congenital Stahl's ear, 5 cases of congenital cup-shaped ear and 5 cases of congenital cryptotia.@*Results@#Total 15 patients were followed up for 12-18 months after the surgery. The area of concha cartilage resection was about 0.5 cm×1.0 cm. The shape and size of the repaired ears were similar to the healthy ear. The transplanted cartilages were not absorbed or deformed. The incision was healed well and retroauricular flap, retroauricular fascia, and skin grafting were preserved well without complications like hemorrhage, necrosis, and infection.@*Conclusions@#This method is harmless and simple, which has reliable and satisfactory effects on various auricular deformities.
