Study on development of voice and velopharyngeal competency in child

本研究从唇腭裂儿童嗓音共鸣的咽功能发展的观点出发，进行了各种实验和调查，并作为研究报告进行了调整。具体内容如下：第一章研究了唇腭裂儿童婴儿期哭声的声学特征、鼻音化程度及其发展变化。在本研究之前，进行了初步调查，比较了测量结果和言语治疗师的听力判断由KAY用于调查的Nasometer。结果证明了该机器的有效性。在主要研究中，与唇裂儿童进行了对比检查，当双咽功能不全包括影响哭泣声音的早期阶段时，以及出生后四个月，清楚地表明双咽功能也开始起作用，以发出喊叫声。 ...更多信息 对鼻共振正常的非腭裂儿童进行鼻倾斜度检查，并提取数据，以获得临床测试时所需的基准点。这些数据被显示出来。唇腭裂儿童与非唇腭裂儿童中无鼻音的儿童相比，鼻音程度明显偏低。因此，很明显，有必要使用非腭裂儿童的数据来建立一个基准点，并创建检查语句，并将一个地区的方言添加到检查中。在第三章中，详细说明了对70名唇腭裂儿童进行二期腭裂修复术的长期观察的结果。腭裂术后至6岁时，患者的咽功能均有明显改善。这是什么表明，一个功能不是立即获得后，一种方式，但这继续获得发展。少

Various experiments and investigations were conducted from a viewpoint of development of velopharyngeal competency about the resonance of the voice of Cleft lip and palate children, and adjustment was performed as a research report. The contents are as follows.In Chapter 1,the acoustic feature of the crying sound of the babyhood stage of cleft lip and palate children, nasalance degree, and those development-change were investigated. In advance of this research, the pilot survey which compares the measurement result and the hearing judging of a speech therapist by Nasometer by KAY used for investigation was carried out. As a result, the validity of this machine was proved. In main investigation, comparison examination with cleft lip children was performed, and when velopharyngeal incompetency consisted of an early stage in affecting a crying sound, and four months after the birth, it was shown clearly that velopharyngeal competency begins to work also to shout utterance.In Chapter 2,260 … More non Cleft palate children which has normal nasal resonance in order to acquire a required fiducial point when using for a clinic test nasalance degree obtained using Nasometer was inspected, and data were extracted. This data was shown. As compared with cleft lip and palate children which does not have hypernasality in non Cleft palate children, nasalance degree showed the clear low value. Therefore, it became clear that it was necessary that the data of non Cleft palate children is used for a setup of a fiducial point and to create the inspection sentence which also added the dialect of an area to examination.In Chapter 3,the result of having observed velopharyngeal competency for a long period of time was explained in full detail about 70 Cleft lip and palate children which carried out 2stage palatoplasty. The improvement of velopharyngeal competency was found over the long period of time to 6 years old after palatoplasty operation. It was what shows that a function is not immediately obtained after a way but this continues being gained in development. Less
