CPAP를 활용한 비인강폐쇄부전 환자의 언어치료 효과

Velopharyngeal incompetence(VPI) is that soft palate and muscle of posterolateral pharyngeal wall can not close velopharyngeal port properly. Thing that prior to treatment for patient with VPI is to evaluation about nasopharyngeal closing function. This data is important for making a treatment plan and assesment of treatment effect to improve nasopharyngeal closing function. There are two ways of VPI assessment. The one is subjective method by auditory finding, the other is objective method by using equipment for language test. Using only subjective way is not adequate for evaluation of VPI because of low trust, so doing both two methods simultaneously help to make a diagnosis and assessment exactly. CPAP is effective method to treat hypernasality. This new treatment technique intensify oropharyngeal muscle for nasopharyngeal closing by direct resistance training. Becase conventional treatments have limitation, so many research about treatment effectiveness of CPAP are being studied. This study aims that we compare our result from Korean VPI patients with result about treatment effect in other advanced country, to make CPAP Treatment Questionares and to find ways that improve oropharyngeal closing function an[1 maximally increase language treatment effect.
