Submucous cleft palate (SMCP) is a congenital condition related to abnormal muscle attachments within the soft palate. Even though hypernasality and nasal emission, the primary symptom of SMCP, have been well-documented, research on articulation errors is currently lacking. The object of this study was to examine the consonant articulation in patients with unoperated SMCP and its possible correlation with the velopharyngeal function. This study analyzed the perceptual speech assessment and nasopharyngoscopy data of 338 patients with unoperated SMCP between years 2008 and 2016 retrospectively. The mean age of the patients was 13.27 years. About 125 patients showed velopharyngeal competence (VPC), 174 velopharyngeal incompetence (VPI), and 39 marginal VPI (MVPI). Among the 338 patients, 137 presented normal articulation, 124 consonant omission, 25 compensatory articulation, 36 consonant weakening, 51 consonant substitution, and 36 posterior placement. About 70.40% VPC patients, 17.24% VPI patients, and 48.72% MVPI patients demonstrated normal articulation. About 59.20% VPI patients showed consonant omission. The results demonstrated that consonant articulation varied among patients with unoperated SMCP and was correlated with their velopharyngeal functions, while consonant omission was the most common articulation error. Velopharyngeal closure pattern was not associated with either velopharyngeal function or consonant articulation.
黏膜下腭裂（SMCP）是一种与软腭内肌肉附着异常相关的先天性疾病。尽管作为SMCP主要症状的高鼻音和鼻漏气已有充分记录，但目前缺乏关于发音错误的研究。本研究的目的是检查未经手术治疗的SMCP患者的辅音发音及其与腭咽功能的可能相关性。本研究回顾性分析了2008年至2016年间338例未经手术治疗的SMCP患者的语音感知评估和鼻咽镜检查数据。患者的平均年龄为13.27岁。约125例患者表现为腭咽功能正常（VPC），174例为腭咽功能不全（VPI），39例为边缘性VPI（MVPI）。在这338例患者中，137例发音正常，124例存在辅音省略，25例存在代偿性发音，36例存在辅音弱化，51例存在辅音替代，36例存在后置发音。约70.40%的VPC患者、17.24%的VPI患者和48.72%的MVPI患者发音正常。约59.20%的VPI患者存在辅音省略。结果表明，未经手术治疗的SMCP患者的辅音发音各不相同，且与他们的腭咽功能相关，而辅音省略是最常见的发音错误。腭咽闭合模式与腭咽功能或辅音发音均无关联。
