Three dimensional analysis of the plane that includes each semicircular canal is essential for understanding the vestibule-ocular reflex evoked in each plane. The fact that the semicircular canals do not lie in single planes has been reported. We measured the helical angle of the plane where each semicircular canal existed using a simulated 3D model of the inner ear and a software-based three-dimensional computed tomographic (3D-CT) imaging program. The diameter of each semicircular canal was also measured. The helical angle was the greatest in the anterior semicircular canal both in measurement of the models and the software-based images. The diameter was the greatest in the anterior semicircular canal when measured in the models. It is suggested that the helical angle of the semicircular canal potentially influences the sensitivity of the vestibulo-ocular reflex (VOR) that the semicircular canal evokes in each plane. A sufficient VOR may be evoked in the plane less strictly determined.
