Values are presented as mean±SD.
ipsi, ipsilateral; L, left; R, right; NS, not significant.
Groups A–D indicate 1–6, 7–12, 13–18, and >18 years old group, respectively; Pab, Pac, Pad, Pbc, Pbd, Pcd indicate P-value for differences between groups A and B, between groups A and C, between groups A and D, between groups B and C, between groups B and D and between groups C and D, respectively; ∠ indicate the angle between 2 planes; A, H, and P indicate the anterior, horizontal, and posterior semicircular canal plane, respectively.
