Videoendoscopic diagnosis for predicting the response to the oral appliance therapy in obstructive sleep apnea syndrome

虽然有一些关于预测治疗结果的实践参数的研究，但预测阻塞性睡眠呼吸暂停（OSA）患者对口腔矫治器（OA）治疗的反应尚不可能。我们在此报告更多的数据和发现，以预测鼻内镜治疗OA的结果。这些结果表明，鼻内窥镜检查腭咽比检查口下咽更有助于预测口腔矫治器的治疗效果。即使是严重的OSA患者，通过推进下颌骨使气道通畅而扩大，对OA治疗也有积极的反应；相反，气道狭窄的患者如果没有通过下颌骨前移而变宽，则对OA治疗没有反应。

Predicting which patients will respond to oral appliance (OA) therapy in obstructive sleep apnea (OSA) is not yet possible, although there are several studies of practice parameters predicting treatment outcome. We report herein additional data and findings for the purpose of predicting OA treatment outcome using nasendscopy. These results suggest that nasendoscopy of the velopharynx is more helpful than examining the oro-hypopharynx to predict oral appliance treatment outcome. Even severe OSA patients with clear airways that widened by advancing the mandible responded positively to OA therapy ; on the contrary, patients with narrowed airways that did not widen by advancing the mandible did not respond to OA therapy.
