The Application Of Costal Cartilage Scaffold Combined With Cranial Auricle Upper And Lower Cross-docking Skin Flaps In Nagata Auricular Reconstruction Stage Ⅱ

ObjectiveTo investigate the application and clinical effect of costal cartilage scaffold combined with cranial auricle upper and lower cross-docking skin flaps in Nagata stage Ⅱauricle Reconstruction.MethodsWe observed 18 patients who were diagnosed with congenital unilateral microtia and experienced Nagata stage Ⅰ operation.They underwent stage Ⅱ auricular forming and reconstruction of the cranioauricular angle using costal cartilage scaffold combined with cranial auricle upper and lower cross-docking skin flaps from June 2016 to 0ctober2018.Brief surgical procedure: lifted auricle scaffold,placed the cartilage scaffold in the cranial groove,and posterior auricular fascia encapsulated cartilage scaffolds.Two long strips of helix angle skin flap were designed in the mastoid region.Close to the cranial groove,draw each other,cross and suture.Skin graft on the remaining wounds.The operation was performed by the same surgeon.ResultsWe followed up for 6-12 months.The clinical effect of all cases was remarkable.Skin flap survived.The angle between the auricle and the lateral side of the skull was about 30 degrees,and the cranial groove formed clearly and obviously.ConclusionThe application of costal cartilage scaffold combined with cranial auricle upper and lower cross-docking skin flaps for reconstruction of cranioauricular angle in Nagata Ⅱ ear reconstruction may present a more stereoscopic and satisfactory cranioauricular angle structure.The operation is relatively simple.It dose not increase the number of operationand it may low the rate of scar contracture after the operation.It is worthy of clinical application.
