To explore the application of the remnant in repairing the reconstructed ear in microtia.
From October 2000 to July 2006, 1,823 patients with reconstructed ear underwent the second operation for repairing. The remnants were used to reconstruct tragus, antitragus, crus of helix, concha cavum, or relax the adhesion between the reconstructed auricle and cranio wall, or insert into the reconstructed lobule or under the basement of the costal cartilage frame to restore the cranio-auricular angle or to the preauricular subcutaneous to correct the facial local depression.
In 1,823 cases, the tragus, antitragus and concha cavum was reconstructeded by remnant auricle in 1,180 cases; helix crus was repaired by remnant auricle in 743 cases; the wound was repaired by remnant auricle flap resulted from relaxing the adhesion between the reconstructed auricle and cranial wall in 68 cases; Subcutaneous and cartilage flap was formed and transferred in 95 cases, and among them the flap was transferred under the basement of the frame to restore the cranio-auricular angle in 77 cases and was transferred to the preauricular subcutaneous to correct the facial local depression in 18 cases; the skin flap was formed by remnant auricle to repair the lobule in 37 cases. All flaps survived completely. The appearance of reconstructed ear was satisfied.
The remnant is very useful in repairing the reconstructed ear in microtia. It should be preserved propriately in auricular reconstruction.
探讨残耳在先天性小耳畸形耳廓再造修复中的应用。
2000年10月至2006年7月，对1823例耳廓再造术后患者进行二期修复手术。利用残耳再造耳屏、对耳屏、耳轮脚、耳甲腔，或松解再造耳廓与颅侧壁的粘连，或植入再造耳垂或肋软骨支架基底下方以恢复颅耳角，或转移至耳前皮下矫正面部局部凹陷。
1823例中，利用残耳再造耳屏、对耳屏和耳甲腔1180例；修复耳轮脚743例；松解再造耳廓与颅侧壁粘连形成残耳皮瓣修复创面68例；形成皮下及软骨瓣并转移95例，其中转移至肋软骨支架基底下方恢复颅耳角77例，转移至耳前皮下矫正面部局部凹陷18例；利用残耳形成皮瓣修复耳垂37例。所有皮瓣全部成活，再造耳外形满意。
残耳在先天性小耳畸形耳廓再造修复中具有重要应用价值，在耳廓再造时应妥善保留。
