Thirty consecutive patients with clinical manifestations of velopharyngeal insufficiency were evaluated by the radiographic techniques of 70 mm lateral stills and lateral cinefluorography. The purpose of this study was to make retrospective comparisons between the actual decisions on velopharyngeal competency or incompetency which were originally made on the basis of cinefluorographic findings with those which we believe would have been made from that information obtained from lateral stills alone had the lateral stills been the only radiographic information available. The results of the comparison between the two techniques suggests that one is apt to misdiagnose the presence or absence of velopharyngeal insufficiency on the order of 30% of th time when relying on the lateral still X-ray technique alone. We attribute this potential error rate to the very limited speech sample that can be employed with the lateral still technique. With the increasing number of secondary procedures available for treating VP dysfunction it is our opinion that cine- or videofluoroscopy allows the clinician to examine additional aspects of the patient's palatal function that are as important in the final management decision as simply the identification of closure or the lack of closure of the velopharyngeal sphincter.
对30例有腭咽功能不全临床表现的连续患者，采用70mm侧位静止片和侧位荧光电影摄影技术进行评估。本研究的目的是对最初基于荧光电影摄影结果做出的关于腭咽功能正常或异常的实际诊断，与我们认为若仅根据侧位静止片所获信息（假设侧位静止片是唯一可用的影像学信息）做出的诊断进行回顾性比较。两种技术的比较结果表明，仅依靠侧位静止X线技术时，大约有30%的几率会误诊腭咽功能不全的存在与否。我们将这种潜在的错误率归因于侧位静止技术所能采用的语音样本非常有限。随着治疗腭咽功能障碍的二次手术数量不断增加，我们认为荧光电影或视频荧光检查能让临床医生检查患者腭部功能的其他方面，这些方面在最终治疗决策中与单纯确定腭咽括约肌的闭合或未闭合同样重要。
