目的 探讨鼻中隔偏曲患者两侧窦口鼻道复合体 (ostiomeatalcomplex ,OMC)的解剖变异。方法 对 10 3例不同部位鼻中隔偏曲的患者作鼻内窥镜检查和鼻窦冠状位、轴位CT扫描 ,比较两侧OMC解剖变异发生率和鼻窦炎发病率的差异。结果 偏曲对侧中、下鼻甲肥大的发生率明显高于同侧 (P <0 .0 5 ) ,筛泡和鼻丘气房的宽度也明显大于同侧 (配对t检验 ,P <0 .0 1) ;中鼻甲反常曲线偏曲同侧的发生率明显高于对侧 (配对t检验 ,P <0 .0 1) ,其它解剖变异偏曲两侧差异无显著性。偏曲两侧鼻窦炎的发病率差异无显著性 (P >0 .0 5 )。结论 鼻中隔偏曲可能引起偏曲对侧中鼻甲及鼻腔外侧壁结构的代偿性改变 ,这种改变可能在偏曲对侧鼻窦炎的发病中起着一定的作用。
Objective To investigate the anatomic variation of ostiomeatal complex (OMC) on both sides of nasal septum deviation patients. Methods 103 cases of nasal septum deviation in different parts of the nasal endoscopy and coronal sinus CT scan axial comparison of both sides of the OMC anatomical variation and the incidence of sinusitis differences. Results The incidence of middle turbinate and inferior turbinate hypertrophy in the contralateral side was significantly higher than that on the ipsilateral side (P <0.05). The width of the antrum and nasal cavity was also significantly larger than that of the ipsilateral (paired t test, P <0. 0 1). The incidence of ipsilateral middle trochlear abnormal curve was significantly higher than that of contralateral (paired t test, P <0.01). There was no significant difference in other anatomical deviations between the two sides. There was no significant difference in the incidence of sinusitis on both sides of deviation (P> 0.05). Conclusion Partial deviations of the nasal septum may cause compensatory changes in the structure of contralateral middle turbinate and nasal lateral wall, which may play a role in the pathogenesis of lateral contralateral sinusitis.
