When moving a local flap, a dog ear sometimes appears at the base of the flap. If we try to correct the dog ear primarily, the blood supply to the flap may be disturbed. In such a case, the dog ear is prone to be corrected secondarily. In the present report we show a new technique for correcting a dog ear that enables correction to be done primarily and sufficiently. The principle of the technique is to de-epithelialise the dog ear portion and dig it in to the dermis to preserve the subdermal plexus at the base of the flap intact. This method is useful especially at the base of a transposition flap because the pedicle tends to be narrowed by the conventional correction.
在移动局部皮瓣时,皮瓣基部有时会出现“狗耳”。如果我们试图一次性矫正“狗耳”,皮瓣的血供可能会受到干扰。在这种情况下,“狗耳”往往需要二期矫正。在本报告中,我们展示了一种矫正“狗耳”的新技术,该技术能够一次性充分完成矫正。该技术的原理是去除“狗耳”部分的上皮,将其埋入真皮,以保持皮瓣基部的皮下血管丛完整。这种方法尤其适用于易位皮瓣的基部,因为传统矫正往往会使蒂变窄。
