Abstract: 目的改进既往Muller动作的纤维鼻咽喉镜检查和常规的多导睡眠描记(polysomnography,PSG)监测,观察药物诱导睡眠下纤维鼻咽喉镜和PSG监测的所见,探讨同步检查的可行性.方法前瞻性自身对比研究.药物诱导睡眠下的纤维鼻咽喉镜检查和PSG监测,之前或之后予常规的纤维鼻咽喉镜检查和PSG监测,观察两者检测结果的差别.结果 32例阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea hypopnea syndrom ,OSAHS)患者中,鼻咽狭窄17例,均伴有口咽狭窄;鼻咽、口咽伴有喉咽狭窄8例;2例为口咽狭窄,伴扁桃体肥大,5例为喉咽狭窄.其中悬雍垂腭咽成形术后3例中,2例为喉咽狭窄,1例为鼻咽狭窄.药物诱导睡眠下的PSG监测与常规PSG监测结果明显相关.但异常程度高于常规的检查.药物睡眠呼吸暂停指数的下降同步于咽部的阻塞,但恢复迟于咽部的阻塞.三部位均狭窄的睡眠呼吸暂停低通气指数(apnea-hypopnea index, AHI)改变最为严重,鼻咽并口咽次之,再次为单独的喉咽或口咽狭窄.结论药物诱导睡眠下的纤维喉镜和PSG监测可以清楚的显示鼻咽、软腭、舌根在鼾声和OSAHS中的动态变化,在观察鼻咽、口咽阻塞的同时,同步记录到OSAHS的存在及程度,为从形态学和机能学的角度深入分析鼾声和OSAHS提供了可能.
