鼻甲泡的CT评估

目的 总结CT对鼻甲泡的评估价值并探讨其临床意义。材料与方法 所谓鼻甲泡是指中鼻甲的气化。37例鼻窦炎者与24例正常人CT检查资料进行对照比较。结果 CT能清晰显示微小鼻甲泡,对鼻窦解剖结构及变异的显示满意。鼻窦炎组鼻甲泡的发生率为37．8％,对照组鼻甲泡的发生率为45．5％,两组间鼻甲泡的发生率无显著差异。检出3例鼻甲泡内息肉,3例鼻甲泡炎,1例鼻甲泡粘液囊肿。2例巨鼻甲泡致OMC阻塞,合并额窦、筛窦和上颌窦炎症。结论 CT是检出鼻甲泡的金标准。鼻甲泡是引发鼻窦炎的潜在因素,关键在于它的大小和部位。

CT evaluation of concha bullosa

Objective To summarize the role of CT in evaluating concha bullosa(CB) and investigate its clinical values. Methods Aeration of the middle turbinate is termed "concha bullosa" (CB) . In total 37 cases with sinusitis were compared with 24 normal subjects in this study. Results CT demonstrated small CB and the detailed anatomy and variations of OMC. The incidence of CB in sinusitis group was 37.8% and 45. 5% in control group. No statistical difference was found between both groups. In 3 cases CB was accompanied with polyps, with infection in another 3 cases, and with mucocele in 1 case. In 2 cases OMC were obstructed by giant CB, resulting in secondary infection of the ethmoid, frontal, and maxillary sinuses. Conclusion CT findings are the gold standard for the diagnosis of CB. CB is one of potential causes of secondary sinusitis, mainly depends on its size and position.
