This study examined the estimation of modeled palatopharyngeal orifice areas under conditions similar to those created by pharyngeal flap reconstruction. Results indicated that accurate estimates of the palatopharyngeal orifice area can be obtained using Warren's pressure-flow approach when the calculated area is actually the combined area of the lateral palatopharyngeal port openings. Our findings lend additional support to the view that pressure-flow techniques can provide objective information about the degree to which surgical procedures provide palatopharyngeal competence for speech.
本研究检测了在与咽瓣重建所产生的条件相似的情况下，对模拟腭咽口面积的估计。结果表明，当计算出的面积实际上是腭咽外侧端口开口的组合面积时，使用沃伦压力-流量法可以获得腭咽口面积的准确估计值。我们的研究结果进一步支持了以下观点，即压力-流量技术可以提供关于手术程序为言语提供腭咽功能的程度的客观信息。
