This study aimed to determine sinus tympani, subtympanic sinus (STS), facial sinus (FS) morphologies, and type distributions. Type distributions were based on their relations with the facial nerve (FN). A total of 20 right and 20 left temporal dry bones without physical deformation were scanned with a MicroCT device. All measurements were made using MicroCT programs from sections in the axial plane. For the FS, the average depth was measured as 3.485 mm without any classification, and 29 of the 40 bones had Type C radiological morphology. The mean depth for all sinus tympanicus was 2.646 mm, and 22 of the 40 bones had Type B morphology. For the STS, 29 out of 40 samples had no contact with the FN; regardless of the classification, the average depth was measured as 2.376 mm. We reveal the depths of the tympanic cavities and their relationship with the FN. The results of this study may benefit clinicians performing retrotympanum surgeries.
本研究旨在确定鼓窦、鼓室下窦（STS）、面窦（FS）的形态以及类型分布。类型分布基于它们与面神经（FN）的关系。使用微型计算机断层扫描（MicroCT）设备对总共20块右侧和20块左侧无物理变形的颞骨干燥骨进行扫描。所有测量均使用MicroCT程序在轴向平面的切片上进行。对于FS，在未进行任何分类的情况下，平均深度测量为3.485毫米，40块骨头中有29块具有C型放射学形态。所有鼓窦的平均深度为2.646毫米，40块骨头中有22块具有B型形态。对于STS，40个样本中有29个与FN无接触；无论分类如何，平均深度测量为2.376毫米。我们揭示了鼓腔的深度及其与FN的关系。本研究结果可能对进行鼓室后手术的临床医生有益。
