Table I.

Audio-impedancemetric data of the study group: SSCD side = side affected by superior semicircular canal dehiscence; ABG = mean air-bone gap between gap values at 250 and 500 Hz on the pathological ear; Ca = tympanometric peak compliance on the affected ear; SRa = stapedial reflexes on the affected side; Cb = tympanometric peak compliance on the healthy ear; SRb = stapedial reflexes on the healthy side; |ΔC| = absolute value of inter-aural difference between tympanometric peak compliances; |ΔC%| = absolute value of inter-aural asymmetry ratio between tympanometric peak compliances; M = male; F = female; R = right; L = left; P = present; A = absent.
