摘　　要：目的观察正常人额隐窝区域气房的分布类型及测定各类型气房的出现率。方法对于符合病例选择标准的24例正常人,用64层螺旋CT常规扫描鼻窦,然后在图像工作站上进行轴位重建(层厚0.6mm,层距0.4mm),并在相同的条件下进行冠状位、矢状位重建,应用图像分析软件观察额隐窝气房的分布类型,并统计各类的出现率。结果48侧额隐窝区域三维影像中,鼻丘气房出现率为92%。额气房出现率为54%,其中Ⅰ型29%,Ⅱ型10%,Ⅲ型15%,未见Ⅳ型额气房。额隐窝后组气房出现率为83.3%,其中眶上筛房出现率为35%,额泡气房出现率为15%,筛泡上气房出现率为33.3%。额窦间隔气房出现率为19%。同侧鼻丘气房与额隐窝后组气房的同时出现率为79.2%。结论多层螺旋CT对分析复杂的额隐窝区域气房及制定手术方案提供很大的帮助。Objective To observe the distribution pattern of frontal recess cells and to determine the frequency of each category cell in healthy adult. Methods 24 patients who met the inclusion criteria were undergone spiral computed tomography at Siemens 64 - slice scanners. The images were reconstructed on a computer workstation, the multislice computed tomographic images were analysis by using software and the prevalence of each category cell of the frontal recess was analysed. Results Of 48 frontal recesses,the presence of agger nasal cell was 92% （44 sides）and frontal cells was 54% （26 sides） ,in which, the prevalence of type Ⅰ , type Ⅱ , type Ⅲ and type Ⅳ were 29% （14 sides）, 10% （5 sides）, 15% （7 sides） and 0% （0 side ） ,respectively. The posterior frontal recess cells were identified in 40 sides （83.3%） , the prevalence of supraorbital ethmoid cell, frontal bullar cell and suprabullar cell were 35% （17 sides） , 15% （7 sides） and 33.3% （ 16 sides） respectively. Interfrontal sinus septal cell were noted in 9 sides （ 19% ）. Ipsilateral agger nasal cell and the posterior frontal recess ceils were simultaneously present in 38 sides （79.2%）. Conclusion Multi - slice spiral CT provides a reliable platform for the analysis of frontal recess cells and anatomy,which is very helpful in planning surgical process.
