In this prospective study, we looked for correlations between anatomic variants of paranasal sinuses and chronic or recurrent sinusitis.
MATERIAL/METHODS: Two hundred and forty (240) patients with clinical features of chronic rhinosinusitis were examined; patients with first-onset or allergic sinusitis and pregnant females were excluded. Routine multi-slice CT of the paranasal sinuses was performed to look for mucosal disease of the paranasal sinuses, drainage pathways, and presence of anatomical variations and their relation to known sinus drainage pathways.
Anatomic variations were very frequent, and we classified them into four easily recognized groups: nasal septum variations, middle turbinate variations, uncinate process variations, and ethmoidal variations. Deviated nasal septum was the most frequent variation in patients with chronic or recurrent sinusitis, and it was detected in 48.8% of cases. Agger nasi cells and concha bullosa were equally frequent (30.6%), and Haller cells were detected in 11.2%. Uncinate process variations were detected in 18.1%, and the large ethmoid bulla was detected in 10%.
The importance of anatomic variations is that they can compromise drainage pathway of the related sinus, which results in inflammatory sinus disease. Anatomical variations are not diseases on their own and may be present as incidental findings in patient with chronic sinusitis.
在这项前瞻性研究中，我们探寻了鼻窦解剖变异与慢性或复发性鼻窦炎之间的相关性。
材料/方法：对240例具有慢性鼻-鼻窦炎临床特征的患者进行了检查；排除了初发性或过敏性鼻窦炎患者以及怀孕女性。进行了鼻窦常规多层CT检查，以查找鼻窦的黏膜病变、引流途径、解剖变异的存在情况及其与已知鼻窦引流途径的关系。
解剖变异非常常见，我们将其分为四个易于识别的组：鼻中隔变异、中鼻甲变异、钩突变异和筛窦变异。鼻中隔偏曲是慢性或复发性鼻窦炎患者中最常见的变异，在48.8%的病例中被检测到。鼻丘气房和泡状鼻甲同样常见（30.6%），Haller气房在11.2%的病例中被检测到。钩突变异在18.1%的病例中被检测到，大筛泡在10%的病例中被检测到。
解剖变异的重要性在于它们可能会损害相关鼻窦的引流途径，从而导致鼻窦炎性疾病。解剖变异本身并非疾病，可能作为慢性鼻窦炎患者的偶然发现而存在。
