摘要
目的:通过影像学观测影响鼻内镜中鼻甲腋区进路行额窦手术的解剖因素。方法:选择无额窦病变患者30例,行鼻窦螺旋CT检查,观察和测量额窦相关影像学解剖数据。结果:中鼻甲前缘在鼻腔外侧壁上的附着点为起点,其到筛顶的垂直距离为(13.88±2.59)mm,到额窦引流通道前壁水平距离为(5.77±2.32)mm。到鼻腔前壁的水平距离为(13.67±2.54)mm,到眶纸板的水平距离为(5.89±1.69)mm。各径值左右两侧差异无统计学意义(P>0.05)。结论:16排螺旋CT结合三维重建技术能为鼻内镜中鼻甲腋区进路额窦手术提供有价值的影像信息。
Objective：To observe the CT imaging features of anatomic structure related to endoscopic axilla approach for surgery of the frontal recess and frontal sinus. Method：Thirty patients without a history of frontal sinus disease were undergone 16 line high speed spiral computed tomography. The computed tomographic images were analyzed to measure the related structures. Result：The vertical distance from the front attachment point of the middle turbinate to the skull base was 13.88±2.59 mm. The horyzontal distance from the top point of the axilla of the middle turbinate to the anterior wall of the frontal sinus outflow tract was 5.77±2.32 mm, to the anterior wall of the nasal cavity was 13.67±2.54 mm,to the lamina papyracea or lacrimal sac was 5.89±1.69 mm. Conclusion：Sixteen line high speed spiral computed tomography is helpful to endoscopic axilla approach for surgery of the frontal recess and frontal sinus.
