In this study, we present a modified technique for primary cleft lip repair with a rotation triangular flap from the cleft lateral side to reconstruct the nasal floor; and evaluate the outcome compared with traditional Millard repair. 40 patients with unilateral cleft lip were included in this research. The patients were divided into 2 groups; 17 patients treated with the Millard technique, and 23 patients treated with the newly modified technique. 14 measurement indexes were employed to evaluate the nose-lip morphology of postoperative patients with UCCL in standardized photographs preoperatively, postoperatively and 1-year follow-up. For lip symmetry, statistical significance was detected in the measurements of the vertical philtral height ratio indicating that the newly modified technique resolve the shortage of lip height on the cleft side 1-year follow-up. ( < .05). In addition, statistical significance was detected in the 1-year postoperative columellar angle, alar width ratio, nostril width ratio, nostril height ratio, and nostril shape (cleft) ( < .05), showing more successful repair of the nose compared with the traditional repair. The modified unilateral cleft lip repair with rotation triangle flap from the cleft lateral side was beneficial in the correction of lip and nasal deformity in and had positive effects on labial symmetry.
在本研究中，我们提出了一种改良技术，即采用来自裂隙外侧的旋转三角瓣进行一期唇裂修复以重建鼻底；并与传统的米勒德修复术比较评估疗效。本研究纳入了40例单侧唇裂患者。患者被分为两组；17例采用米勒德技术治疗，23例采用新改良技术治疗。采用14项测量指标，在术前、术后及1年随访时的标准化照片中评估单侧完全性唇裂术后患者的鼻唇形态。对于唇对称性，在人中垂直高度比的测量中检测到统计学显著性差异，表明新改良技术在1年随访时解决了裂隙侧唇高不足的问题（P<0.05）。此外，在术后1年的鼻小柱角、鼻翼宽度比、鼻孔宽度比、鼻孔高度比及鼻孔形状（裂隙侧）方面检测到统计学显著性差异（P<0.05），表明与传统修复相比，鼻修复更成功。采用来自裂隙外侧的旋转三角瓣改良单侧唇裂修复术有利于矫正唇鼻畸形，对唇部对称性有积极影响。
