腭裂术后构音障碍患者音韵历程的初步分析

目的：分析腭裂术后构音障碍患者音韵历程，为语音治疗提供依据。方法：对46例腭裂术后构音障碍患者的语音资料进行回顾性分析，从腭咽闭合功能、腭瘘、辅音正确构音率（ percentage of consonant correct，PCC）与音韵障碍的相关性方面进行统计研究。结果：46例构音障碍患者中37例出现结构历程，均为声母省略；34例出现位置替代历程，均为后置化；40例出现方法替代历程。患者音韵的结构历程、位置替代历程与PCC分级有相关性。结论：PCC分级高的患者与声母省略的结构历程和后置化的位置替代历程相关。

Phonological process analysis of articulation disorders of patients with cleft palate after operation

Objective:To explore the phonological process of articulation disorders of patients with cleft palate after operation and provide more evidence for speech therapy.Methods:Forty-six subjects with cleft palate after operation with ar-ticulation disorders were included.The patient ’ s velopharyngeal function, palatal fistula, percentage of consonant correct ( PCC) were retrospectively analyzed.The factors relating were analyzed by the correlation coefficient.Results:Thirty-seven
subjects had initial consonant omission of construction process.Thirty-four subjects had backing of positional substitution process.Forty subjects had manner substitution process.The construction process and positional substitution process were re-lating to the PCC grade.Conclusion:Higher PCC grade were relating to patient’ s construction process and positional substi-tution process.
