目的 :探讨颅咽腔的变化在睡眠呼吸暂停综合征 (OSAS)患者发病中的意义。方法 :对 5 0例健康成人用荷兰菲利浦公司SCT 70 0 0型螺旋式全身扫描机进行颅咽腔测量。测定 :①鼻咽腔层面 (咽隐窝和咽鼓管口均清楚的层面 ) ;②口咽腔层面 (口咽腔最狭小的层面 ) ;③喉咽腔层面 (会厌软骨刚刚显示的层面 )。各组数字作t检验。结果 :口咽腔 (2 .2 8± 1.17)cm2 ,鼻咽腔 (4.39± 1.5 2 )cm2 (P <0 .0 5 ) ,喉咽腔 (3.83± 1.5 7)cm2 (P <0 .0 5 )。结论 :正常人口咽腔是口咽部生理性狭窄的部位 ,也最易发生阻塞。其大小的改变对OSAS的发病有重要影响。
Objective: To investigate the significance of changes in the craniopharyngeal cavity in the pathogenesis of sleep apnea syndrome (OSAS). Methods: Fifty healthy adults were diagnosed by cranial pharynx with a Philips SCT 70 0 screw-type scanner. Determination: ① nasopharyngeal cavity level (pharyngeal crypt and eustachian tube orifice are clearly the level); ② oropharyngeal cavity level (the oropharyngeal cavity the most narrow level); ③ hypopharyngeal cavity level (epiglottis cartilage has just shown the level) . Each group of numbers for t test. Results: The oropharyngeal cavity (2.28 ± 1.17) cm2, the nasopharyngeal cavity (4.39 ± 1.52) cm2 (P0.05), the hypopharyngeal cavity (3.83 ± 1.57) cm2 (P0.01) 5). Conclusion: The normal pharyngeal cavity is the site of physiological oropharyngeal stenosis, and is also the most prone to obstruction. The size of the change has an important impact on the incidence of OSAS.
