窦口鼻道复合体 (ostiomeatalcomplex ,OMC)是近年鼻内窥镜检查和手术开展后提出的新名称 ,此区域是前组鼻窦引流的所在部位 ,也是功能性鼻内窥镜手术的重点区域 ,手术若对该处病变清除不彻底 ,会影响手术治愈率和复发率 ;若术前对OMC解剖变异认识不足 ,可能造成手术损伤 ,产生严重并发症。目前 ,影像学检查是评价OMC解剖变异和判定病变位置、范围的主要方法 ,随着检查手段的日新月异 ,鼻窦平片已难以提供令人满意的影像 ,MRI对鼻窦的正常骨性结构及炎性病变病因的观察价值不大 ,常规CT扫描中冠状位高分辨率CT是显示OMC结构的最佳技术 ,螺旋CT三维重建技术和CT仿真内窥镜成像技术由于其各自的优越性 ,在OMC区的临床应用很有潜力。现将OMC的影像学研究进展作一综述 Ostiomeatal complex (ostiomeatalcomplex, OMC) is a new name proposed in recent years after nasal endoscopy and surgery. This area is the site of anterior sinus drainage, and is also the focus of functional endoscopic sinus surgery. Surgery if the disease is not completely cleared of the disease there, will affect the surgical cure rate and recurrence rate; if preoperative awareness of OMC anatomical variations lack of awareness, may result in surgical injury, resulting in serious complications. At present, imaging examination is the main method to evaluate the anatomical variation of OMC and to determine the location and extent of the lesion. With the rapid change of examination methods, it is difficult to provide satisfactory images of sinusoidal plain film. The normal bony structure and inflammatory The etiology of the lesion is of little value in the diagnosis. Conventional CT scan with high resolution coronal CT is the best technique to show the structure of OMC. Because of their respective superiority, three-dimensional reconstruction of CT and CT virtual endoscopy are more effective in OMC The clinical application has great potential. Now OMC imaging research to make a review
