摘要: 目的：测量半规管相互间及其与参考水平面的夹角，明确半规管夹角变异是否与BPPV发病相关。方法：选取2023年至2025年间桂林市中医医院30例原发性BPPV患者和30例健康人群，通过磁共振3D-FIESTA序列测量半规管相互夹角以及各半规管和参考水平面的夹角，比较两组间差异。结果：人体半规管并非完全相互垂直，三个半规管相互角度平均值为92.3˚，其中最大角度为116.6˚，最小角度为66.8˚；观察组在右前–右后、左前–左后、双侧外半规管–参考水平面、左后半规管–参考水平面的夹角与对照组差异均具有统计学意义(P < 0.05)。结论：人体半规管并非完全相互垂直，不同个体的半规管夹角存在差异性；BPPV患者的部分半规管相互角度与对照组相比存在显著差异，这种解剖变异可能与BPPV的发生有关。
Abstract: Objective: To measure the angles between the semicircular canals and their angles relative to the reference horizontal plane, and to determine whether variations in semicircular canal angles are associated with the onset of BPPV. Methods: In this study, 30 patients with primary BPPV and 30 healthy individuals were selected from Guilin Hospital of Traditional Chinese Medicine between 2023 and 2025. The angles between the semicircular canals and the angles between each semicircular canal and the reference horizontal plane were measured using the 3D-FIESTA sequence of magnetic resonance imaging, and the differences between the two groups were compared. Results: The human semicircular canals were not completely perpendicular to each other. The mean angle among the three semicircular canals was 92.3˚, with a maximum angle of 116.6˚ and a minimum angle of 66.8˚. In the observation group, the angles of right anterior - right posterior, left anterior - left posterior, bilateral horizontal semicircular canal - reference horizontal plane, and left posterior semicircular canal - reference horizontal plane were all significantly different from those in the control group (P < 0.05). Conclusion: The human semicircular canals are not completely perpendicular to each other, and variations in semicircular canal angles exist among different individuals. Some inter-semicircular canal angles in BPPV patients differ significantly from those in the control group, and such anatomical variations may be related to the occurrence of BPPV.
