This study performed volumetric analysis and classified different repeated patterns of temporal bone pneumatization in adults using cone beam computed tomography (CBCT) scans.
A total of 155 temporal bones were retrospectively evaluated from 78 patients with no radiographic evidence of pathology. Two reference structures were used to classify temporal bone pneumatization into 3 groups. Volumetric analysis of the pneumatization was performed using a window thresholding procedure on multiplanar CBCT images. Correlation between direct communication of peritubal cells with the eustachian tube and the degree of pneumatization was also assessed.
Using 2 reference structures, pneumatization pattern in the temporal bone can be classified into 3 groups. Statistically significant differences were present in their mean volumes between 3 groups. Statistically significant correlation was found between degree of pneumatization and presence of peritubal cells associated with ET.
This study showed that CBCT can be effectively used for imaging temporal bone air cavities and for volumetric assessment.
本研究利用锥形束计算机断层扫描（CBCT）对成人颞骨气化进行容积分析，并对不同的重复气化模式进行分类。
对78例无影像学病理证据患者的155块颞骨进行回顾性评估。使用两个参考结构将颞骨气化分为3组。在多平面CBCT图像上采用窗阈值法对气化进行容积分析。还评估了咽鼓管周围细胞与咽鼓管直接连通与气化程度之间的相关性。
利用两个参考结构，颞骨气化模式可分为3组。3组之间的平均体积存在统计学显著差异。气化程度与与咽鼓管相关的咽鼓管周围细胞的存在之间存在统计学显著相关性。
本研究表明，CBCT可有效用于颞骨气腔成像和容积评估。
