Abstract:
Objective:To evaluate semicircular canal damage and its frequency characteristics in Meniere disease patients.
Methods:Sixty-seven Meniere disease patients accepted the video-head impulse test(vHIT)which responses to semicircular canal function of high frequency area, head shaking test(HST) which responses to semicircular canal function of middle frequency area, and caloric test(CT) which responses to semicircular canal function of low frequency area.Preferences were recorded including the video head impulse test gain (vHIT-G), head shaking nystagmus (HSN) and parameters of the unilateral weakness (UW) as observation index, and results of all the three tests were analyzed according to Meniere disease patients. SPSS 17.0 software was used to analyzed the data.
Results:The positive rate of CT, HSN and vHIT were 70.1%(47/67), 41.8%(28/67) and 23.9%(16/67) respectively. Comparation of the positive rate among CT, HST and vHIT showed statistically significant difference (χ2=10.93, P=0.001; χ2=28.79, P=0.000). Comparation of the positive rate between HST and vHIT showed statistically significant difference(χ2=4.87, P=0.027).
Conclusions:Semicircular canal function damage in Meniere disease patients mainly presents in the low frequency area, which indicates a characteristic phenomenon that low-frequency function area (caloric test results) is more predisposed to be involved than that of middle-frequency function area (head shaking testing)and high-frequency function area (video head impulse testing) in Meniere disease patients.
