摘要

摘要: 目的: 测量半规管空间方向,为良性阵发性位置性眩晕(BPPV)的诊断和治疗提供解剖学基础。方法: 对24例核磁共振3D-CISS序列内耳检查影像进行测量分析。结果: 左右后半规管夹角为106.61°±8.58°,可以推测后半规管和矢状面的夹角为53.31°±4.29°。左右水平半规管夹角为171.67°±4.36°。左侧后半规管和右侧前半规管夹角为154.37°±10.87°,右侧后半规管和左侧前半规管夹角为156.84°±9.34°。结论: 测量数据同既往文献报道相符,左右共同平面对半规管近乎平行,但后半规管和矢状面夹角要大于传统上认为的45°。

Abstract: Objective: Measure the space direction of semicircular canals to provide the anatomical basis for the diagnosis and treatment of BPPV.Method: We calculated angles among semicircular canals of 24 patients using MRI scaning with 3D-CISS sequence.Result: The angle between the left and right posterior semicircular canals was 106.61°±8.58°, so the angle among the posterior semicircular canals and sagittal head plane was 53.31°±4.29°. Pairs of contralateral synergistic canal planes were not parallel, forming 171.67°±4.36° between the left and right horizontal semicircular canal planes, 154.37°±10.87° between the left posterior and right anterior semicircular canal planes and 156.84°±9.34° between the right posterior and left anterior semicircular canal planes.Conclusion: Our measurement of the angles among semicircular canals coincided with those of previous reports. The angles between contralateral synergistic canal planes were close to parallel, but the angle between the posterior semicircular canals and sagittal head plane was great than 45° that traditionally thought to be.
