Haller cells are anterior ethmoid air cells located in the medial orbital floor immediately lateral to the maxillary infundibulum. The purpose of this study was to demonstrate the prevalence and relationship between the existence and size of these cells with ipsilateral maxillary sinusitis and orbital floor dehiscence as visualized on cone beam CT (CBCT) images.
CBCT image volumes of 50 patients were retrieved and analysed. All CBCT images were acquired with a 9-inch field of view scan. χ(2) and Cochran-Mantel-Haenszel tests were used for statistical analysis of the obtained data, and p-values of <0.05 were considered to be statistically significant.
There was no statistically significant association between the existence and size of Haller cells and maxillary sinusitis. There was a significant association between Haller cells and orbital floor dehiscence.
The explanation of maxillary sinusitis on the basis of mechanical obstruction is unlikely. This study provides evidence for the usefulness of CBCT scan in delineation of the sinonasal anatomy.
鼻甲气房位于上颌窦自然开口的内侧,眼眶底壁的内侧,即筛骨纸板。本研究旨在通过锥形束 CT(CBCT)图像,显示鼻甲气房的存在及其大小与同侧上颌窦炎和眶底骨缺损之间的关系。
从 50 名患者中提取和分析了 CBCT 图像。所有 CBCT 图像均采用 9 英寸视野扫描。使用卡方检验和 Cochran-Mantel-Haenszel 检验对获得的数据进行统计学分析,p 值<0.05 被认为具有统计学意义。
鼻甲气房的存在和大小与上颌窦炎之间无统计学关联。鼻甲气房与眶底骨缺损之间存在显著关联。
基于机械阻塞解释上颌窦炎的理论不太可能成立。本研究为 CBCT 扫描在鼻窦解剖结构中的应用提供了证据。
