  • APPLICATION OF RESIDUAL EAR IN AURICULAR RECONSTRUCTION OF MICROTIA

    【Abstract】 Objective To summarize different treatments of the residual ear in auricular reconstruction, toinvestigate the reasonable appl ications of the residual ear. Methods From September 2005 to July 2006, 128 patients(79 males, 49 females; aging 5-21 years with an average of 11 years)with unilateral microtia underwent the staged repair. In the patients, there were 44 cases of left-unilaterally microtia and 84 cases of right-unilaterally microtia. The residual ears looked l ike peanut in 56 patients, l ike sausage in 35 patients, l ike boat in 27 patients, and l ike shells in 10 patients. Among all the patients, the external acoustic meatus was normal in 5 patients, stenosis in 11 patients, and atresia in 112 patients. According to auricular developmental condition, the patients were divided into three types: 17 cases of type I, 98 cases of type II, and 13 cases of type III. In the first stage operation, a 50 mL kidney-l iked expander was implanted into post aurem subcutaneous tissue. The residualear whose superior extremity was close to the hair l ine was treated. The middle and superior part of the residual ear was cut. The redundant residual auricular cartilage was removed. In the second stage operation, the inferior part of the cartilage frame was covered by the middle and superior part of the residual ear. According to the location of the residual ear, “V-Y” plasty, “Z”-plasty and reversal of the residual ear were used to correct the location of the residual ear. In the third stage operation, the remained residual ear was used to reconstruct crus of hel ix or cover the wound surface which was resulted from repairing the reconstructed ear. Results The residual ears which were reshaped and transferred had good blood circulation. All residual ears were survival. The wounds healed by first intention. The follow-up for 8-15 months showed that the auricular lobule of the reconstructed ear was turgor vital is and natural. The locations of the reconstructed ear and normal side ear were symmetry. The auricular lobules of the reconstructed ear survived well. The reconstructed crus of hel ix, hel ix, antihel ix and triangular fossawere clear. The results were satisfactory. Conclusion Using residual ear reasonably is an important procedure of successful auricular reconstruction and the symmetry of the reconstructed ear and uninjured side ear.
