The postoperative reconstruction of ear canal cancer with a local flap such as the snail flap technique has been reported for cases with few tissue defects. The snail flap technique requires a large skin incision and is at risk of facial neuropathy. We have devised a new flap that addresses these problems.
An 80-year-old woman underwent total right ear canal resection for cancer of the right ear canal, and the defect of the ear canal was reconstructed using a local flap. The local flap was used by making a rectangular incision in front of the auricle and rolling it into a cylindrical shape. We named this flap a square screw flap.
The patient was discharged 1 week after surgery without complications.
This method is considered to be useful for reconstruction of the ear canal with a small defect.
对于组织缺损较少的病例，已有报道采用局部皮瓣如蜗牛皮瓣技术进行耳道癌术后重建。蜗牛皮瓣技术需要较大的皮肤切口，且存在面神经病变风险。我们设计了一种新的皮瓣来解决这些问题。
一名80岁女性因右侧耳道癌接受了右侧耳道全切除术，并用局部皮瓣重建了耳道缺损。通过在耳廓前方做一个矩形切口并将其卷成圆柱形来使用局部皮瓣。我们将这种皮瓣命名为方形螺旋皮瓣。
患者术后1周出院，无并发症。
该方法被认为对小缺损耳道的重建有用。
