Abstract：
The study aimed to assess the efficacy of buccinator myomucosal flap (BMF) compared to Bardach two-flap use in primary cleft palatoplasty on palatal length and fistulation rate. Palatal length in relation to the pharynx is a critical factor regarding velopharyngeal function. The goal was to predict the risk of velopharyngeal insufficiency by comparing the potential of two different techniques in lengthening the palate and to decrease the fistulation rate. A total of 46 patients with complete wide cleft palate were randomly divided into two equal groups: a study group, in which the cleft palate defect was repaired by BMF; and a control group, in which patients\' clefts were repaired by Bardach (two-flap) palatoplasty during primary repair. All patients were evaluated at 1-, 3- and 6-month intervals to detect the fistulation rate and to measure the palatal length by taking impressions, pouring casts to measure the palatal length from anterior reference point (incisive foramen) to the posterior reference point(uvula) and calculating the change of palatal length. There was a significant increase in the palatal length measurements in the study (BMF) group (immediate postoperatively and at 3 and 6 months) compared to the control group (p < 0.001). Regarding the fistulation rate, there was no statistically significant difference (p = 0.346). The use of the buccinator flap during primary repair of cleft palate decreased the fistulation rate.
摘要：
该研究旨在评估与Bardach双皮瓣相比，在原发性left裂修复术中使用buccinator肌粘膜皮瓣（BMF）对the骨长度和造瘘率的疗效。与咽部有关的腭长度是有关咽喉功能的关键因素。目的是通过比较两种不同技术在延长腭和降低瘘发生率方面的潜力来预测咽喉功能不全的风险。将46例完全性宽腭裂患者随机分为两组:研究组,其中腭裂缺损通过BMF修复；对照组，其中在初次修复期间通过Bardach（双瓣）腭成形术修复了患者的裂隙。所有患者在1-，3个月和6个月的间隔，以检测瘘管率并通过印象来测量腭长度，倾倒铸模，测量前参考点（尖锐孔）到后参考点（悬垂）的腭长度，并计算腭长度的变化。与对照组相比，研究（BMF）组（术后即刻以及3和6个月）的腭长度测量值显着增加（p<0.001）。关于造瘘率，差异无统计学意义(p=0.346)。在c裂的初次修复过程中使用颊肌皮瓣降低了瘘管率。
