DTI parameters for the region of interest (ROI) analysis focusing on the Heschl’s gyrus (HG) while using the forceps major (FM) as an internal control.

		CSNHL Group	Control Group	p
		n = 23	n = 18
		Mean (SD)	Mean (SD)
FA	HG∗	0.24 (0.01)	0.27 (0.03)	<0.01
	FM∗∗	0.27 (0.02)	0.29 (0.02)	<0.01
RD	HG	0.87 (0.02)	0.85 (0.03)	0.08
	FM	0.98 (0.03)	0.99 (0.04)	0.66
AD	HG	0.98 (0.03)	0.97 (0.03)	0.15
	FM	1.13 (0.04)	1.15 (0.04)	0.32

^∗p = 0.0015: when comparing the mean FA value of HG between the CSNHL group and the Control Group. ^∗∗p = 0.0033: when comparing the mean FA value in the FM between the CSNHL group and the Control Group. Values indicate the mean values in each parameter. FA: fractional anisotropy, RD: radial diffusivity, AD: axial diffusivity.
