We have studied the mechanism of velopharyngeal valving in 27 patients undergoing uvulopalatopharyngoplasty for obstructive sleep apnea before and after surgery. The patients were assessed by peroral examination and nasendoscopy. Our observations and findings of the readaptation process of the velopharyngeal valve following the operation show us that its different closure patterns are due to a variable anatomy. A certain compensatory mechanism is possible mainly in the circular pattern and the circular pattern with Passavant's ridge and sagittal patterns. Passavant's ridge is an anatomic variant rather than a compensatory mechanism. The muscularis uvulae is important mainly in nonphonetic activities of the velopharyngeal valve. This information is important for clinical purposes in order to better correct problems associated with velopharyngeal incompetence.
我们研究了27例因阻塞性睡眠呼吸暂停接受悬雍垂腭咽成形术的患者手术前后腭咽瓣关闭的机制。通过经口检查和鼻内镜检查对患者进行评估。我们对术后腭咽瓣再适应过程的观察和发现表明，其不同的关闭模式是由于解剖结构的差异。主要在环形模式、有帕萨万特嵴的环形模式和矢状模式中可能存在某种代偿机制。帕萨万特嵴是一种解剖变异，而非代偿机制。悬雍垂肌主要在腭咽瓣的非语音活动中起重要作用。这些信息对于临床目的很重要，以便更好地纠正与腭咽功能不全相关的问题。
