Evaluation of Superior Semicircular Canal Morphology and Its Relationship with Glenoid Fossa Roof Thickness Using Cone Beam Computed Tomography

Table 4

The relationship between the presence/absence of SSCD and the dehiscence/thickness of the RGF thickness.

		SSCD		OR (95% CI)	-value
		No	Yes
RGF	≤1 mm	396 (90.4%)	42 (9.6%)		0.008
	1 < RGF ≤ 2 mm	103 (99%)	1 (1%)	0.09 (0.01–0.67)
	>2 mm	12 (100%)	0 (0%)	0.90 (0.87–0.93)
Dehiscence of the GF	No	465 (96.1%)	19 (3.9%)	12.93 (6.59–25.37)	≤0.001
	Yes	46 (65.7%)	24 (34.3%)

SSCD: superior semicircular canal dehiscence; RGF: roof of the glenoid fossa; GF: glenoid fossa, OR: odds ratio; CI: confidence interval.
