CPAP治疗腭裂术后鼻音功能亢进的个案研究

A case study of the effects of continuous positive airway pressure treatment on the hypernasal patient after cleft palate surgery

目的 通过对一例腭裂术后腭咽闭合功能不全患者进行治疗,探索解决此类患者鼻音功能亢进问题的有效方法.方法 对该患者实施持续正性气压通气（continuous positive airway pressure, CPAP）治疗,利用＂鼻流量检测仪＂监控其鼻音功能改善情况.采用单一被试实验设计,检验患者治疗前后鼻流量各项指标是否存在差异.结果 该患者发/a/、/i/、/u/音和说＂姥姥有鱼＂句子时的鼻流量均有明显下降.结论 CPAP治疗对于改善腭裂术后因腭咽闭合不全所致的鼻音功能亢进为有效.

objective This case study intends to assess the effects of treating the hypernasality of the patients with velopharyngeal incompetence （VPI） after the cleft palate surgery. Methods By the single baseline A-B experimental design, a VPI patient was treated with continuous positive airway pressure（CPAP） program and measured with Nasoview to observe the differences before and after the treatment. Results The study showed that the nasalance values of/a/,/i/, /u/ and ＂lao lao you yu＂ reduced significantly in this patient after the treatment. Conclusion The CPAP program is effective for the VPI patient with hypernasality after the cleft palate surgery.
