目的 :探讨窦口鼻道复合体发育不良、解剖变异对慢性副鼻窦炎的影响程度。方法 :收集经CT冠状面扫描发现的慢性副鼻窦炎 70例。重点观察钩突、中鼻甲、鼻中隔的发育形态、位置。测量钩突的内偏角及外偏角度 ,测量鼻中隔偏曲的突出度与偏曲角度 ,行统计处理并分析解剖变异与慢性鼻窦炎的关系。结果 :70例慢性副鼻窦炎与窦口 鼻道复合体的发育不良、解剖变异有明显的相关性。钩突、中鼻甲及鼻中隔的解剖结构变异为主要的影响因素。结论 :CT冠状面扫描能清楚地显示窦口 鼻道复合体的解剖变异及慢性副鼻窦炎的部位及程度。多种解剖变异并存时往往同时引起多窦腔炎症 ,受累最重的是上颌窦其次是筛窦
Objective: To investigate the degree of dysplasia of ostiomeatal complex and the influence of anatomical variation on chronic sinusitis. Methods: Seventy patients with chronic sinusitis were collected by coronal CT scan. Focus on the hook, middle turbinate, nasal septum developmental morphology, location. The angle of deviation and angle of deviation of the uncinate process were measured to measure the deviation and deviation angle of nasal septum deviation. The relationship between anatomical variation and chronic sinusitis was analyzed statistically. Results: There were significant correlations between 70 cases of chronic sinusitis and dysplasia and anatomic variation of ostiomeatal complex. Histopathies, middle turbinate and nasal septum anatomical variations as the main influencing factors. Conclusion: CT coronal scan can clearly show the anatomical variation of ostiomeatal complex and the location and extent of chronic sinusitis. A variety of anatomical variations co-exist often lead to multiple sinus inflammation, the most affected is the maxillary sinus followed by the ethmoid sinus
