发音辅助装置在唇腭裂患者语音治疗中的临床应用

目的用口腔修复学的方法制作发音辅助装置,治疗唇腭裂患者因软腭组织缺损、运动障碍所引起的发音异常。方法常规采取上颌印模,灌注石膏模型,使用热凝树脂等材料,根据口腔内缺损情况制作两种发音辅助装置。结果第1组病例3人戴入辅助软腭运动型发音辅助装置后,配合语音训练,语言清晰度明显提高。第2组病例2人戴入腭咽腔闭合型发音辅助装置后,鼻音减弱,同时进行语音训练,语言清晰度较之前有很大提高。结论腭咽腔闭合型发音辅助装置和辅助软腭运动型发音辅助装置,是治疗腭咽腔闭合功能不全、软腭运动障碍的有效方法。

The Clinical Effect of Pronunciation aid Device in the Pronunciation Treatment of Cleft lip and Palate Patients

Objective A pronunciation aid device had been made by using dental prosthodontic method for the treatment of pronunciation disorder, which is caused by movement dysfunction because of defect of soft palate tissues in cleft lip and palate patients.Methods According to the defect condition in the mouth, two types of pronunciation aid devices had been produced regularly by using maxillary impression, plaster casting and thermoplastic resin materials and so on. Results In the first group of cases, after 3 patients were wearing soft palate movement pronunciation aid device, and then they were given pronunciation training, it is found that their language clearances degrees had been promoted obviously. In the second group of cases, 2 patients were wearing naso-pharynx cavity closing pronunciation aid device, it is found that their nasal sound and nasal leakage were disappeared. And in the same time we gave patients pronunciation training, and after one year, their language clearances degrees were found to be more obviously increased than before.Conclusions Naso-pharynx cavity closing pronunciation aid device and soft palate movement pronunciation aid device are an effective non-surgical treatment methods for the treatment of naso-pharynx cavity closing dysfunction and soft palate movement dysfunction.
