Lateral speech videofluoroscopic evaluations were videotaped preoperatively and postoperatively for 20 patients who underwent sphincter pharyngoplasty. Randomized videotapes were constructed and subsequently evaluated by speech/language pathologists experienced in assessing patients with velopharyngeal dysfunction. Rating forms assessing various motion parameters of the posterior pharyngeal wall were completed and analyzed statistically. Results showed that the posterior pharyngeal wall configuration postoperatively was less likely to be rated as smooth relative to the preoperative configuration (p = 0.019). No other statistically significant data were obtained, although there was a trend for posterior pharyngeal wall movement rated as discrete preoperatively to be described as generalized postoperatively. We conclude that when comparing preoperative and postoperative parameters, sphincter pharyngoplasty does not significantly affect posterior pharyngeal wall motion. Posterior pharyngeal wall configuration is less likely to be categorized as smooth after sphincter pharyngoplasty relative to the preoperative condition. Although sphincter pharyngoplasty has been shown to improve velopharyngeal function, there is little evidence from this study to suggest that preexisting posterior pharyngeal wall motion causes sphincteric movement.
对20例行括约肌咽成形术的患者术前和术后进行了侧面言语电视透视评估并录像。制作了随机录像带，随后由在评估腭咽功能障碍患者方面经验丰富的言语/语言病理学家进行评估。完成了评估咽后壁各种运动参数的评分表并进行了统计学分析。结果显示，相对于术前形态，术后咽后壁形态被评为光滑的可能性较小（p = 0.019）。虽然术前被评为离散的咽后壁运动术后有被描述为普遍化的趋势，但未获得其他具有统计学意义的数据。我们得出结论，在比较术前和术后参数时，括约肌咽成形术不会显著影响咽后壁运动。相对于术前情况，括约肌咽成形术后咽后壁形态不太可能被归类为光滑。虽然括约肌咽成形术已被证明可改善腭咽功能，但本研究几乎没有证据表明先前存在的咽后壁运动导致括约肌运动。
