目的 加深对鼻腔和鼻窦疾患及其相关性的认识。材料与方法 搜集经手术病理证实的鼻腔鼻窦炎性疾患 82例 ,CT轴位扫描 63例 ,冠状位扫描 19例 ,将鼻腔与鼻窦病变进行对比分析。结果 中上鼻道息肉与各鼻窦炎关系密切 ;对于上颌窦、后组筛窦和蝶窦炎 ,中上鼻道息肉与粘膜肿胀间均无显著性差异 (P >0 .0 5 ) ;对于前组筛窦和额窦炎 ,中上鼻道息肉与粘膜肿胀组间有显著性差异 (前组筛窦P <0 .0 5 ,额窦P <0 .0 1) ;息肉与粘膜肿胀均表现为软组织影 ,除非息肉呈结节状 ,否则单从CT影像上难以区别 ;中上鼻道息肉可以引起邻近骨质吸收脱钙。结论 中上鼻道息肉是各鼻窦炎发生的主要原因之一 ,它较粘膜肿胀更易引起前组筛窦和额窦炎。
Objectives To deepen the understanding of nasal and sinus disorders and their relevance. Materials and Methods 82 cases of nasal sinusitis, confirmed by pathology, were collected. 63 cases of CT axial scan and 19 cases of coronal scan were selected for comparative analysis of nasal and sinus lesions. Results In the maxillary sinus, posterior ethmoid sinus and sphenoid sinusitis, there was no significant difference between the middle and upper nasal polyps and mucosal swelling (P> 0.05) There was a significant difference between the anterior ethmoid sinus and frontal sinusitis, the middle and upper nasal polyps and the mucosal swelling group (anterior ethmoid sinus P <0. 05, frontal sinus P <0. 01), polyps and mucosal swelling The performance of soft tissue, unless polypoid nodular, or single from the CT image is difficult to distinguish; middle and upper nasal polyps can cause proximal bone resorption decalcification. Conclusion The middle and upper nasal polyps is one of the main causes of sinusitis, which is more likely to cause mucosal swelling than the former ethmoid sinus and frontal sinusitis.
