Articulation, resonance, and velopharyngeal function were evaluated before and after Le Fort I maxillary advancement in 16 patients (seven with cleft lip and palate, one with cleft lip only, and eight without clefts). On the postoperative evaluation, seven of 11 patients with preoperative articulation errors showed an improvement in articulation after surgery. Two patients without clefts showed slight changes in nasal resonance, and two patients (one with cleft lip and palate and one with cleft lip only) developed mild nasal emission. Nine patients showed diminished velopharyngeal contact during speech on videofluoroscopic studies. Compensatory changes in velopharyngeal function were also observed, which included velar stretching and lengthening and increased lateral pharyngeal wall movement.
对16例患者（7例唇腭裂、1例单纯唇裂、8例非唇腭裂）在Le Fort I型上颌骨前徙术前和术后进行了构音、共鸣及腭咽功能评估。术后评估时，11例术前存在构音错误的患者中有7例术后构音改善。2例非唇腭裂患者鼻腔共鸣有轻微变化，2例患者（1例唇腭裂、1例单纯唇裂）出现轻度鼻漏气。9例患者在电视荧光透视检查中显示讲话时腭咽接触减少。还观察到腭咽功能的代偿性变化，包括软腭伸展和延长以及咽侧壁运动增加。
