The total surface areas of human mastoid air cells were measured using digital CT scans. Using 24 normal ears, the lining of the mastoid air cells was digitally scanned, traced and analysed. The mean surface area of the mastoid air cell system was 167.0 cm2 and ranged from 74.78 to 330.01 cm2. The volume was also measured, the mean being 10.43 cm3 ranging from 6.25 to 20.52 cm3. The correlation coefficient between surface area and volume was 0.95. These results indicate that well pneumatized mastoid air cells serve to provide an extremely large surface area in the temporal bone which in normal mastoid air cells is proportional to the volume.
利用数字CT扫描测量人类乳突气房的总表面积。对24只正常耳朵的乳突气房内衬进行数字扫描、追踪和分析。乳突气房系统的平均表面积为167.0平方厘米，范围在74.78至330.01平方厘米之间。还测量了体积，平均值为10.43立方厘米，范围在6.25至20.52立方厘米之间。表面积与体积之间的相关系数为0.95。这些结果表明，气化良好的乳突气房有助于在颞骨中提供极大的表面积，在正常乳突气房中，该表面积与体积成正比。
