Abstract

Background: Temporal bone pneumatization (TBP) is influenced by age, sex, and race, and it seems to progress rapidly to puberty. However, the extent of TBP in childhood remains unclear.

Purpose: To investigate the progression of TBP in children aged 1-18 years via three-dimensional (3D) reconstruction of high-resolution computed tomography (CT) images.

Material and methods: A total of 432 temporal bones of 216 individuals aged 1-18 years with well-pneumatized mastoid antra on both sides were included in this retrospective work. We created 18 age groups, each with six boys and six girls. Surface rendering of air density was performed using -290 HU to obtain TBP. Statistical analysis employed SPSS version 24.0 software (IBM Corp., Armonk, NY, USA).

Results: The linear regression equations that considered age and volume for all cases (y_a), male (y_m) and female (y_f) were y_a= 384.42x + 1790.40, R²= 0.425; y_m= 431.54x + 1440.9, R²= 0.501; and y_f= 337.26 x + 2140.5, R²= 0.355. Both male and female individuals showed an increase in the average value of pneumatization until the age of 17, and the values of pneumatization at specific ages for boys and girls showed differences. The mean male and female TBP levels differed significantly at 3, 11, and 18 years of age (P < 0.05).

Conclusion: TBP in boys was greater than that of girls at adolescence. It was possible to identify the specific periods of significant variation in the degree of pneumatization of temporal bone.

利用三维重建计算机断层扫描分析颞骨气化的生长模式。

背景：颞骨气化（TBP）受年龄、性别和种族的影响，似乎在青春期进展迅速。目的：通过对高分辨率计算机断层扫描（CT）图像进行三维（3D）重建，研究 1-18 岁儿童颞骨气化的进展情况：这项回顾性研究共纳入了 216 名 1-18 岁儿童的 432 块颞骨，这些儿童的两侧乳突窦气化良好。我们创建了 18 个年龄组，每个年龄组有 6 个男孩和 6 个女孩。使用 -290 HU 对空气密度进行表面渲染，以获得 TBP。统计分析采用 SPSS 24.0 版软件（IBM 公司，美国纽约阿蒙克）：所有病例（ya）、男性（ym）和女性（ef）的年龄和体积的线性回归方程为 ya = 384.42x + 1790.40，R2 = 0.425；ym = 431.54x + 1440.9，R2 = 0.501；ef = 337.26 x + 2140.5，R2 = 0.355。男性和女性的气化平均值在 17 岁之前都呈上升趋势，而男孩和女孩在特定年龄段的气化值则存在差异。在 3 岁、11 岁和 18 岁时，男性和女性的 TBP 平均值有显著差异（P 结论：男性的 TBP 值高于女性的 TBP 值，而女性的 TBP 值低于男性的 TBP 值）：在青春期，男孩的 TBP 要高于女孩。可以确定颞骨气化程度显著变化的特定时期。
