摘要
目的通过CT扫描确定阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea-hypopnea syn-drome,OSAHS)病人上气道阻塞部位,指导临床制订治疗方案,判断治疗效果。方法对30例OSAHS病人进行上气道CT扫描,分别测量鼻咽、口咽及喉咽腔横截面积。与30名正常成人进行比较。结果OSAHS病人咽腔3个部分的横截面积自小至大顺序排列为口咽<鼻咽<喉咽;OSAHS病人鼻咽及口咽横截面积与正常成年人相比有统计学意义(P<0.01)。18例OSAHS病人在接受了悬雍垂腭咽成形术(UPPP)手术术后进行上气道CT扫描,口咽部平均横截面积由(67.5±16.78)mm2扩大至(156.63±28.62)mm2(P<0.001)。结论正常成人口咽部是咽腔最狭窄的部位;OSAHS病人口咽部横截面积小于100 mm2时,建议手术治疗。UPPP术后上气道CT扫描可客观判定手术效果。
Objective To analyze the role of upper airway CT scan for the diagnosis and treatment of obstructive sleep apnea-hypopnea syndrome （OSAHS）. Methods The size of upper airway, including nasopharyax, oropharynx, and laryngopharynx, in 30 patients with OSAHS and 30 normal controls were evaluated by CT scan. Results The spatial sizes of oropharynx and nasopharynx in OSAHS patients were significantly smaller than those of normal controls （ P 〈 0.01 ） . The transverse - section areas of oropharynx in 1 8 patients were significantly increased after UPPP surgery （ P 〈 0. 001）. Conclusion CT scan is a valuable tool for assessing the size of upper-airway, for determining the approaches of operation, and for evaluating the effect of UPPP surgery.
