多层螺旋CT 及气道三维重建在阻塞性睡眠呼吸暂停综合征中的诊断价值

目的：分析应用多层螺旋CT及气道三维重建技术评价阻塞性睡眠呼吸暂停综合征患者咽壁软组织和上气道狭窄情况。方法选取该院92例阻塞性睡眠呼吸暂停综合征患者作为观察组，另取92例健康人作为对照组，对全部患者进行多层螺旋CT及气道三维重建技术检查，统计并比较观察组与对照组患者咽壁软组织和上气道狭窄情况。结果观察组患者的舌后区、腭后区及喉咽部的气道与对照组相比明显狭窄（P＜0．05）；观察组患者的咽壁软组织较厚，软腭的长度和宽度均大于对照组（P＜0．05）。结论应用多层螺旋CT及气道三维重建技术可以有效地评估阻塞性睡眠呼吸暂停综合征患者的咽壁软组织和上气道狭窄情况。

The evaluation of obstructive sleep apnea syndrome using multi-slice spiral CT and 3D airway reconstruction technology

Objective To analyze the application of multi‐slice spiral CT and 3D airway reconstruction technique on obstruc‐tive sleep apnea syndrome (OSAS) of pharyngeal soft tissue and upper airway stenosis .Methods Selected 92 patients with OSAS in our hospital as the observation group and another 92 healthy persons were selected as control group ,all patients achieved multi‐slice CT and 3D airway reconstruction technical inspections ,counted and compared their pharyngeal soft tissue and upper airway stenosis .Results Airway stenosis of tongue back ,and hypopharynx retro‐palatal of control group were more narrow compared with the control group(P<0 .05);the observation group′s pharyngeal soft tissue was more thick than the control group ,so as the length and width(P< 0 .05) .Conclusion Multi‐slice spiral CT and 3D airway reconstruction technique can effectively share pharyngeal soft tissue and upper airway stenosis of patients with OSAS .
