We investigated the inner ear anatomy accurately in detail by microcomputed tomography (micro-CT) to contribute to the data related to the inner ear anatomy and the potential clinical contribution of these data in the treatment of the inner ear's pathologies.
AIMS/OBJECTIVES: This study aimed to define a range for normal measurements of the VA, vestibule, lateral semicircular canal, and cochlea. We scanned temporal dry bone samples at high resolution using micro-CT.
Forty dry temporal bones used in anatomy student education were included in this study with a micro-CT device. All measurements were made on sections in the axial plane with micro-CT programs.
The operculum and the vestibular aqueduct middle diameters median values were 0.487 mm and 0.294 mm, respectively. The median value of middle diameters for the nonampullated section of lateral semicircular canal was 1.103 mm. The mean height of the cochlea was 3.417 mm and the width of the cochlea was 5.615 mm. The mean length of the vestibule was 6.085 mm and the width of the vestibule was 3.002 mm.
We present a database that clinicians can consider in their studies by creating normal anatomical values measured with high precision for the bone labyrinth.
我们通过微计算机断层扫描（micro-CT）详细准确地研究内耳解剖结构，为内耳解剖学相关数据以及这些数据在治疗内耳疾病方面的潜在临床贡献提供参考。
本研究旨在确定 VA、前庭、外半规管和耳蜗的正常测量范围。我们使用 micro-CT 对颞骨干标本进行高分辨率扫描。
本研究纳入了 40 个用于解剖学学生教育的颞骨干标本，使用 micro-CT 设备进行研究。所有测量均在轴向平面的切片上通过 micro-CT 程序进行。
镫骨和前庭水管中间直径的中位数分别为 0.487mm 和 0.294mm。非壶腹段外半规管中间直径的中位数为 1.103mm。耳蜗的平均高度为 3.417mm，耳蜗的宽度为 5.615mm。前庭的平均长度为 6.085mm，前庭的宽度为 3.002mm。
我们提供了一个数据库，临床医生可以通过为骨迷路测量高精度的正常解剖值来考虑在他们的研究中使用。
