目的:探讨窦口鼻道复合体(OMC)间隙狭窄与慢性鼻窦炎的关系及其狭窄的原因。方法:对94例(179侧)有鼻塞、流涕、头痛等症状的患者,采用PICKER IQ CT机冠状位扫描,高空间分辨率算法成像,对比分析正常鼻窦和有炎症鼻窦的OMC间隙狭窄及其OMC变异情况。结果:正常鼻窦与有炎症鼻窦间OMC间隙狭窄发生率的差异有统计学意义(均P<0.01),但OMC解剖变异发生率的差异无统计学意义(P>0.05)。结论:OMC间隙狭窄与鼻窦炎有重要关系,了解鼻窦炎患者各种OMC间隙狭窄的特点,有助于功能性内镜鼻窦手术。
Objective: To investigate the relationship between stenosis of the ostiomeatal and nasal complex (OMC) and chronic sinusitis and its causes. Methods: Ninety-four patients (179 patients) with nasal obstruction, runny nose, headache and other symptoms were examined by PICKER-CT scan and high-spatial resolution imaging. The OMC space stenosis between normal sinus and inflammatory sinus and The OMC variation. Results: There was significant difference in the incidence of OMC interspace stenosis between normal sinus and inflamed sinus (all P <0.01), but there was no significant difference in the incidence of OMC dissection (P> 0.05). Conclusion: OMC interstitial space stenosis has an important relationship with sinusitis. To understand the characteristics of various OMC interspace stenosis in patients with sinusitis, which is helpful for functional endoscopic sinus surgery.
