窦口鼻道复合体的常见解剖变异及其CT表现
Common Anatomic Variations and CT Findings of OMC Body

目的：分析窦口鼻道复合体的解剖变异和鼻窦病变的关系，分析其在内窥镜鼻窦手术中的重要性。方法：搜集本附属医院经CT冠位扫描及鼻窦内窥镜手术患者共55例，重点观察筛漏斗、半月裂孔、钩突、鼻甲气房、Haller气房的解剖变异与病变，结合病史分析解剖变异与鼻窦病变的关系。结果：本组发生OMC解剖变异共47例(占85.5%)，变异可单独存在、也可多种并存，包括钩突变异40 (72.7%)、中鼻甲变异31 (53.4%)、鼻丘过度气化18 (32.7%)、筛泡过度气化34 (61.8%)、Haller气房21 (38.2%)。结论：CT图像能清楚显示窦口鼻道复合体的解剖变异以及鼻窦病变的部位、程度和性质，为鼻窦内窥镜手术提供可靠的解剖证据和手术方案。
Aim: To analyze the relationship between anatomic variations and sinus lesions OMC body, and analyze its importance in endoscopic sinus surgery. Methods: After collecting hospital coronal CT scan and endoscopic sinus surgery in patients with a total of 55 cases, the paper focused on sieve funnel, a half split, uncinate, turbinate gas room, anatomic variations and disease of Haller gas room, and combined with medical history to analyze the relationship between anatomical variation and sinus disease. Results: OMC anatomic variations occurred 47 cases (85.5%). The variation can exist alone, but also a variety of coexistence of different mutations includes hook 40 (72.7%), middle tur-binate variation 31 (53.4%), nasal mound over gasification 18 (32.7%), ethmoid bulla excessive gasification 34 (61.8%), and Haller gas room 21 (38.2%). Conclusion: CT images can clearly show anatomical variations of ostiomeatal complex, and parts, extent and nature of sinus disease and provide anatomical evidence and reliable solutions for endoscopic sinus surgery surgery.
