单侧唇裂修复术中唇红三角瓣术前术后定量分析

目的:单侧唇裂红唇修复中唇红三角瓣的设计进行术前数据的定量分析,及通过术后数据的定量分析对术后效果进行评价。方法:青岛大学附属医院26例单侧唇裂患儿,手术前后进行健患侧各项数据的测量,术前数据包括健患侧唇长、干唇长、唇红三角瓣边长及底长;利用医学统计学方法得出术前数据的相关性并进行唇红三角瓣的设计,为单侧唇裂唇红修复时三角瓣的设计提供理论参考。术后测量数据包括健患侧唇长、干唇高度及唇高,运用医学统计学分析健患侧有无差异,从主观及客观两方面分析术后唇红部形态、对称性及患儿上唇唇红部形态等,综合评价手术中设计唇红三角瓣的效果。结果:唇裂裂隙程度与唇红三角瓣底长有明显的相关性,术前健侧与裂隙缘唇峰干唇的高度差和红唇三角瓣底长呈正相关(P＜0.05);26例唇红修复主观评价项平均得分均大于4分,客观评价术后健患侧干唇高度、唇高、唇长均无差异,整复效果令人满意。结论:依照本文设计唇红三角瓣的方法修复单侧唇裂可使上唇唇红获得良好形态效果。

Quantitative Analysis of Triangular Vermilion Flap in Unilateral Cleft Lip Repair

Objective: To analyze the preoperative data for the design of vermilion triangular flap, and evaluate the reconstruction effect by quantitative analysis of postoperative data in vermilion reconstruction in unilateral cleft lip. Methods: The measured data before and after operation in 26 cases of unilateral cleft were compared with the healthy side in the Department of Oral and Maxillofacial Surgery of the Affiliated Hospital of Qingdao University. The preoperative measured data included bilateral lip length, dry vermilion length, flap and bottom length of both cleft and non-cleft sides. The relationship of preoperative data were analyzed by medical statistics methods and used for designing the vermilion triangular flap. The postoperative measured data included lip length, dry vermilion and lip height of both cleft and non-cleft side. The correlation of the above data was analyzed by medical statistics method. The results of the designed vermilion triangular were evaluated from the subjective and objective aspects, including the shape and symmetry of lip vermilion. Results: There was a significant correlation between the degree of cleft lip fissure and the design of bottom length of vermilion triangular. The preoperative height difference was positively correlated with the bottom length of vermilion triangular (P＜0.05). The average scores for subjective evaluation items were more than four in all 26 cases. Objective evaluation of postoperative height of dry vermilion and lip in both cleft and non-cleft side showed no differences. Conclusion: The triangular vermilion flap designed in this paper can achieve satisfied upper lip vermilion in the unilateral cleft lip repair.
