为了评估手术后上颌骨推进术后语音和咽腔的变化，我们客观地评估了腭裂术后腭咽闭合不全患者的这些参数。鼻音评分在手术后暂时恶化，但在6个月内恢复。对于因腭裂而行腭裂成形术的腭咽闭合功能不全患者来说，手术上颌骨前移可能是一种有用的策略。

To assess the postoperative speech and pharyngeal space changes after surgical maxillary advancement, we objectively evaluated these parameters in patients with velopharyngeal insufficiency following palatoplasty due to cleft palate.
