摘要：

Objectives: This study was conducted to investigate the angles and orientation of semicircular canals, and the coplanarity of functional canal pairs. Methods: Fluid signals in semicircular canals were reconstructed with three-dimensional reconstruction software using 20 temporal bone magnetic resonance images of normal subjects. The angles between each pair of semicircular canals were measured. Results: The mean angles between the anterior and horizontal semicircular canal plane, the horizontal and posterior semicircular canal plane, and the anterior and posterior semicircular canal plane were 83.7 degrees, 82.5 degrees and 88.4 degrees, respectively. Pairs of contralateral synergistic canal planes were formed 15.1 degrees between the right and left horizontal semicircular canal planes, 21.2 degrees between the right anterior and left posterior semicircular canal, and 21.7 degrees between the left anterior and right posterior semicircular canal. Conclusion: Each semicircular canal makes an almost right angle with other canals, but synergistically acting functional canal pairs of both ears do not lie in exactly the same plane.
