Diagnostic performance results for group A images and group B images in the detection of superior semicircular canal (SSC) dehiscence in 42 patients clinically diagnosed with SSC dehiscence syndrome and in 42 control participants.

	Sensitivity	Specificity	AUC	Accuracy	TP	TN	FP	FN
Group A images	85.7%	100.0%	0.929	92.9%	36	42	0	6
Group B images	97.6%	100.0%	0.988	98.8%	41	42	0	1

Group A images: reformatted CT images of the temporal bone oriented in the standard transverse and coronal planes.

Group B images: reformatted CT images of the temporal bone oriented in parallel (plane of Pöschl) and perpendicular (plane of Stenver) planes to the SSC.

AUC: area under the receiver operating characteristic curve; TP: true positive, TN: true negative, FP: false positive, FN: false negative; CT: computed tomography.
