Comparing mean labyrinthitis ossificans grade by trauma^{^a}

	Mean (SE)		P Value
	No Trauma (n = 50)	Trauma (n = 8)	P Value
Apical turn of cochlea^{^b}	0.75 (0.24)	1.15 (0.60)	.535
Middle turn of cochlea^{^b}	0.80 (0.23)	1.25 (0.58)	.477
Basal turn of cochlea^{^b}	1.0 (0.24)	1.58 (0.60)	.372
Vestibule	0.59 (0.18)	0.44 (0.46)	.763
Lateral semicircular canal	1.82 (0.19)	1.55 (0.48)	.605
Posterior semicircular canal	1.36 (0.21)	0.50 (0.52)	.130
Superior semicircular canal	1.03 (0.22)	0.66 (0.54)	.528

↵a LO grade for each structure within the membranous labyrinth is reported stratified by risk factor. P value is from a mixed-effects model.
↵b Analysis is based on 57 ears (49 with no trauma and 8 with trauma).
