窦口鼻道复合体各结构间隙狭窄与慢性鼻窦炎的相关性研究

Stenosed spaces of ostiomeatal complex in chronic sinusitis

目的:探讨窦口鼻道复合体(OMC)各结构间隙与中鼻甲、鼻中隔间隙狭窄与慢性鼻窦炎的关系及狭窄的主要原因。方法:采用鼻窦冠状位CT扫描,高空间分辨率算法成像分析经鼻内镜手术治疗的89例(171侧)患者的正常鼻窦和炎症鼻窦的OMC各结构间隙的变异情况。结果:正常鼻窦与有炎症鼻窦间OMC各结构间隙狭窄的发生率差异均有统计学意义(P<0.01),OMC各结构间隙与慢性鼻窦炎分别行Logistic回归分析,差异均有统计学意义(P<0.01)。结论:OMC间隙狭窄为鼻窦炎发生的重要危险因素;在鼻窦内窥镜手术治疗鼻窦炎疾病时,必须矫正OMC间隙狭窄。

Objective： To discuss the relationship between the stenosed spaces of ostiomeatal complex （OMC）, middle nasal concha-nasal septum and chronic sinusitis, and the relative factors causing the syenosed spaces. Methods： Eighty-nine patients（ 14-62 years old, 171 sides of nasal cavity and sinns）were examined with coronal and high resolution CT scaning. The CT manifestations of the stenosed spaces of OMC, middle nasal concha-nasal septum and the anatomic variations of OMC were comparatively analyzed between the inflammatory sinuses and the normal ones. Result： The stenosed spaces were different between the inflammatory sinuses and the normal ones and there was significant statistically（ P 〈 0.01）; the OMCs was significantly related with chronic sinusitis（ P 〈 0.01）. Conclusion： Stenosed spaces of OMC is an important factor causing sinusitis and must be corrected in endoscopic sinus surgery（ESS）.
