In a study of 26 normal cadaveric temporal bones, a significant correlation was found between the area of the mastoid air spaces assessed from a conventional lateral radiograph and the mastoid volume as determined using high resolution computed tomography. The relationship, which was found to be linear, is of the form V = 0.82 A + 0.13. The correlation coefficient is 0.95 with a residual standard deviation about the regression of 1.14 cm3. It is apparent, therefore, that an accurate assessment of the mastoid air space volume can be obtained by means of a simple and routinely requested investigation, i.e. the 35 degree lateral oblique radiograph.
在一项对26个正常尸体颞骨的研究中，发现从传统侧位X线片评估的乳突气房面积与使用高分辨率计算机断层扫描确定的乳突体积之间存在显著相关性。这种关系呈线性，形式为V = 0.82A + 0.13。相关系数为0.95，回归的剩余标准差约为1.14 cm³。因此，很明显，通过一项简单且常规要求的检查，即35度侧斜位X线片，就可以获得乳突气房体积的准确评估。
