The velopharyngeal function while swallowing water was studied on a healthy volunteer patient with velopharyngeal closure and on a patient with velopharyngeal insufficiency. This patient suffers from open hypernasality as a result of shortened velum. Both subjects underwent nasoendoscopy with a flexible fiber glass optical device while swallowing water and while articulating the plosive consonant /k/. Velopharyngeal function was documented by means of videotaping and then the single video images were placed together along a time scale to form a new temporal image. This image makes possible a quick and comprehensive differentiation between physiological and disturbed motion patterns as demonstrated in this study using velopharyngeal function as the example. The videotaping in lapse time of such disordered movements can provide indicators of the therapeutical steps to be taken.
对一名腭咽闭合正常的健康志愿者和一名腭咽功能不全的患者进行了吞咽水时腭咽功能的研究。该腭咽功能不全患者因软腭缩短而出现开放性高鼻音。两名受试者在吞咽水和发爆破辅音/k/时，均使用可弯曲纤维玻璃光学装置进行鼻内镜检查。通过录像记录腭咽功能，然后将单个视频图像按时间顺序排列在一起，形成一个新的时间图像。如本研究以腭咽功能为例所示，该图像能够快速、全面地区分生理运动模式和紊乱运动模式。对这种紊乱运动进行延时录像可为采取的治疗措施提供指标。
