CT扫描对儿童鼻窦炎与窦口鼻道复合体关系的评价

目的分析儿童上颌窦炎的CT表现及其与窦口鼻道复合体之间的关系，为儿童上额窦炎的临床治疗提供影像学依据。方法收集经临床诊断的鼻窦炎患儿64例，均行16层CT轴扫及冠状重建，按上颌窦黏膜皱襞厚度不同分为轻度、中度、重度，研究其与窦口鼻道复合体之间的关系。结果68．7％（44／64）上颌窦炎累及其它组副鼻窦，轻度12例（18．8％），中度34例（531％）合并液-气平面10例，重度18例（28.1％）合并液-气平面5例，其它鼻窦累及共44例。鼻道窦口复合体清晰9例，鼻道窦口复合体欠清晰35例，鼻道窦口复合体结构模糊20例，经χ^2检验Pearson相关性及一致性分析，两者有统计学意义（P〈0.05）。结论CT扫描能够清晰显示儿童鼻窦鼻窦炎性病变的范围、程度以及周围变化，良好地显示窦口鼻道复合体结构；儿童上颔窦炎以黏膜皱襞中、重度肥厚常见，儿童窦口鼻道复合体病变与上颌窦炎严重程度呈一致性，两者相互影响。

Objective To analyse the relationship of CT scan results between the children＇s maxillary sinusitis and the ostiomeatal complex（OMC）, For children maxillary sinusitis clinical treatments with ,imaging basis. Methods To collect the clinical diagnosis of 64 cases of sinusitis in children. All were examined with line 16 CT by axial and coronary reconstruction. According to the maxillary sinus mucosa plica thickness, differentcent is mild moderate severe, and to study the relationship between their and ostiomeatal complex. Results 68.7% （44/64） maxillary sinusitis involve the other group of paranasal sinus, mild in 12 cases （18.8%）, moderate 34 cases （53.1%） combined liquid - air plane 10 cases, severe 18 cases （28.1%） combined liquid - air plane in 5 patients, Other sinus involvement 44 cases.The ostiomeatal complex clear 9 cases, the ostiomeatal complex owe blurs 35 cases, ostiomeatal complex structure fuzzy 20 cases,according to the chi-square test Pearson correlation and consistency analysis, both have statistical significance （P〈0.05）. Conclusion The CT scan can clearly shows that children nasal sinus inflammatory lesions of the extent of change and around, good display the structure of ostiomeatal complex; Children maxillary sinusitis with mucosal plica in common and severe hypertrophy, Children ostiomeatal complex lesions and maxillary sinusitis severity is consistency, both influence each other.
