耳后游离皮瓣移植修复鼻部分缺损

目的 应用能携带耳廓软骨，色泽与鼻部相近的小型游离皮瓣修复鼻部分缺损。方法 采用以耳后动、静脉为血管蒂的耳后游离皮瓣行吻合血管的移植，对5例鼻部缺损进行了修复。结果 3例术后皮瓣血运完全正常，2例术后1－4d内有不同程度的静脉回流障碍。5例皮瓣最终全部成活，术后效果较为满意。结论 本手术供区隐藏，皮瓣不臃肿，色泽与鼻部相近，1次手术即可达到较满意的修复效果，是修复鼻尖、鼻翼大部缺损可供选择的一种方法。

Reconstruction of partial nose defects with retroauricular free flap transplantation

OBJECTIVE: To present the operation for nose defect reconstruction using a retroauricular free flap and the auricle cartilage. METHODS: Based on the anatomy and blood supply of the retroauricular region, a flap was designed and harvested with the posterior auricular vessels as its pedicle. The flap was used to repair nose defects in five patients. Of them, three had unilateral subtotal alinasal defects, one had nasal apex defect, and one had defects on nasal apex and bilateral ala. The size of the defect ranged from 2.5 cm x 1.5 cm to 3.0 cm x 4.0 cm. The flap varied between 3.0 cm x 2.0 cm and 4.5 cm x 3.5 cm. In 4 cases, the auricular cartilage of 2.0 cm x 1.5 cm to 1.5 cm x 1.0 cm was taken along with the flap. The posterior auricular vessels were anastomosed with the facial vessels. The donor site was covered with full-thickness skin graft. RESULTS: Postoperatively, the blood supply to the flaps was fairly good in 3 cases, while there was various venous stasis in 2 cases during the first 4 days. However, the postoperative results of the 5 cases were satisfactory. CONCLUSIONS: The retroauricular free flap is a good choice for partial nose reconstruction, which had the merits of well-hidden donor site, good color match, and one-stage operation.
