Diagnostic System for Velopharyngeal Function in Cleft Palate Patients.

为探讨腭裂患者的腭咽功能不全，采用腭咽纤维镜和超声检查进行了系统入路。在本研究中，1。2.超声检查的有用应用；研究了两种考试的同步评估。超声检查的有用应用：观察咽侧壁的动态运动，有助于定性和定量的诊断分析。在本次检查中，使用我们自制的头部定位器固定患者头部和超声晶体。纤维镜和超声检查的同步评估。通过两次检查，可以对腭咽功能进行三维分析。正常受试者的外咽壁内移和外咽壁内移运动同步良好。而腭裂伴腭咽功能不全的患者，腭壁和咽侧壁的运动明显减少，许多功能不稳定。这是可能的评估腭咽功能不全的后续治疗。该系统可用于腭裂患者腭咽功能的评估，超声检查在腭裂儿童中是可行的。

In order to investigate the velopharyngeal insufficiency in cleft palate patients, the systemic approach by means of velopharyngeal fiberscope and ultrasonic examination has been done. In this research,1.useful application of ultrasonic examination, 2.synchronized assessment of both examinations was studied.1. Useful application of ultrasonic examination: The dynamic movement of lateral pharyngeal wall was observed, and it is useful in diagnostic analysis q-alitatively and quantitatively. In this examination, the head positioner of our making was applied to fix the patient's head and ultrasound crystal.2. Synchronized assessment of fiberscopic and ultrasonic examination. It was possible for a three dimentional analysis of velopharyngeal function by two examinations. In normal subjects, the el-vating movement of velar and medial excursion of lateral pharyngeal wall was well synchronized. But in cleft palate pstients with velopharyngeal insufficiency, movement of velar and lateral pharyngeal wall were obviously reduced and unstable in many functions. and it was possible to assess the velopharyngeal insufficiency for the following therapy.This system is useful for assessment the velopharyngeal function in cleft palate patients, and ultrasonic examonation is practicable without trouble in childfood with cleft palate.
