腭咽瓣(VPV)关闭动态检查对鼻音说话病例治疗至关重要。作者对110例说话正常人(NS)和怀疑腭咽功能不全(VPI)40例,施行鼻内窥镜检查,并在说话、强力吸吮法(FST)、发“AH”音和平静时,比较观察 VPV功能和帕萨范嵴(Passavent′s ridge,PR)的形态和位置。FST是由医生指令被检查者用全力吸吮闭塞的5号导管的方法。据VPV、咽侧壁和PR关闭咽管的作用VPV型式有:①NS组冠状60,矢状1,环状26,环状加PR23;当FST及VPV仍未闭允许观察咽壁运动,咽侧壁全内移能见者冠状20/60,矢状1/1,环状15/26,
Hypovolemopathy (VPV) Closure Dynamic examination is crucial for nasal speech therapy. The authors performed a nasal endoscopy on 110 normal-spoken (NS) and suspected velopharyngeal insufficiency (VPI) 40 subjects and compared them with speaking, strong sucking (FST), and “AH” tone and calm The morphology and location of VPV function and Passavent's ridge (PR) were observed. The FST is a method by which a doctor instructs the examinee to suck the occluded Catheter No. 5 with full force. According to the VPV, pharyngeal wall and PR pharyngeal closure of the role of VPV type: ① NS group coronal 60, sagittal 1, 26 ring, plus PR23; when the FST and VPV are still closed to allow the observation of pharyngeal motility, pharynx The wall is fully moved to see the coronas 20/60, sagittal 1/1, ring 15/26,
