The purpose of this study was to investigate the relationship between the pneumatization of mastoid air cells and PNS using three-dimensional (3D) reconstruction of computed tomography (CT) scans of the PNS.
A retrospective review of PNS CT scans from 60 cases was performed. Patients with evidence of sinusitis or mastoiditis, or a history of head trauma, were excluded from the study. Volumes were measured using 3D reconstruction based on axial images of 1 mm thickness. Volumes of the mastoid air cells (right and left), frontal sinus, sphenoid sinus, and maxillary sinuses (right and left) were obtained and compared using statistical analysis.
The volume of mastoid air cells and sinuses did change with age, but the volumes of male subjects were larger than those of females. There was a positive correlation between the pneumatization of mastoid air cells and that of the sphenoid sinus; however, no relationship was observed between the volume of mastoid air cells and that of the maxillary sinuses.
This study examined whether a similarity in pneumatization exists between the mastoid air cells and PNS of individuals; these results may be useful in understanding the normal and pathological conditions of both structures.
本研究旨在通过对鼻窦的计算机断层扫描（CT）进行三维（3D）重建，探讨乳突气房气化与鼻窦之间的关系。
对60例鼻窦CT扫描进行回顾性分析。有鼻窦炎或乳突炎证据、或有头部外伤史的患者被排除在研究之外。基于1毫米厚度的轴向图像，使用3D重建测量体积。获取乳突气房（左右）、额窦、蝶窦和上颌窦（左右）的体积，并进行统计分析比较。
乳突气房和鼻窦的体积确实随年龄变化，但男性受试者的体积大于女性。乳突气房气化与蝶窦气化之间存在正相关；然而，未观察到乳突气房体积与上颌窦体积之间的关系。
本研究探讨了个体的乳突气房与鼻窦之间是否存在气化相似性；这些结果可能有助于理解这两种结构的正常和病理状况。
