The whistling deformity occurs frequently after reconstruction of the bilateral cleft lip, especially when the patient's prolabium is small. Because it is difficult to correct, it is preferable to use an operative technique during primary reconstruction that does not result in this deformity. The method of using a unique pattern for the vermillion flap in all cases of bilateral cleft lip repair eliminates the problem of the whistling deformity and, at the same time, results in a natural looking vermillion.
口哨样畸形在双侧唇裂修复术后经常出现，尤其是当患者的前唇较小时。由于难以矫正，在一期修复时采用一种不会导致这种畸形的手术技术更为可取。在所有双侧唇裂修复病例中，对唇红瓣采用独特的设计方法可消除口哨样畸形问题，同时使唇红外观自然。
