对3例腭裂患者（2例单纯腭裂，1例单侧唇裂、齿槽裂和腭裂）早期手术修复后获得足够的腭咽功能和正常的腭穹隆后所产生的发音错误进行了腭电图（EPG）和声谱图（SG）检查。观察到舌腭接触的共同特征，其中接触面积比正常情况更宽和/或更靠后。这些发音错误可以根据呼气的方向分为三种类型：腭化发音错误（其中空气沿着腭的中线通过），侧向发音错误（其中空气侧向流过咬合的牙弓）和鼻咽发音错误（其中空气流出鼻子）。这三个被认为是类似的难治性后方的发音模式在腭裂患者以前的报告。然而，这些类型的发音错误可以由已经获得足够的腭咽功能和正常腭穹隆的腭裂患者产生。
Misarticulations produced by three patients with cleft palate (2 isolated cleft palate; 1 unilateral cleft lip, alveolus, and palate) who attained adequate velopharyngeal function and normal palatal vault by early surgical repairs were examined using electropalatography (EPG) and sound spectrography (SG). Common characteristics of lingual-palatal contact in which the contact area was broader and/or was more posterior than normal were observed. These misarticulations can be divided into three types based on the direction of the breath emission: palatalized misarticulation (in which air passes along the midline of the palate), lateral misarticulation (in which air flows laterally through the occluded dental arch), and nasopharyngeal misarticulation (in which air flows out the nose). These three are considered to be similar to intractable posterior pattern of articulation in cleft palate patients previously reported. However, these types of misarticulations can be produced by cleft patients who have achieved adequate velopharyngeal function and normal palatal vault.
