ABSTRACT
Objective: To investigate the characteristics of air-conducted sound cervical vestibular evoked myogenic potential （ACS-cVEMP） and bone-conducted vibration cervical vestibular evoked myogenic potential （BCV-cVEMP） in healthy preschool children, and to provide the normal reference range of VEMP for preschool children in China. Methods:Forty-four normal-hearing children （88 ears） aged 3-7 years were recruited to undergo ACS-cVEMP and BCV-cVEMP determination. These children were divided into two groups according to age: 3-4 years old group （ 17 cases, 34 ears） and 5-7 years old group （ 27 cases, 54 ears）. The response rates and waveform parameters were recorded and analyzed statistically using SPSS 18.0 software. Results:The response rates of ACS-cVEMP, BCV-cVEMP in 44 normal-hearing children （88 ears） were 96.59％（85/88） and 97.73％（86/88） respectively, and there was no significant difference between the two groups （P > 0.05）. The response rates of ACS-cVEMP in 3-4 year old group and 5-7 year old group were 94.12% （32/34） and 98.15% （53/54） respectively, and there was no significant difference between the two groups（P>0.05）; The response rates of BCV-cVEMP in 3-4 year old group and 5-7 year old group were 94.12% （32/34） and 100.00%（54/54） respectively, and there was no significant difference between the two groups （P>0.05）. Compared with the 5-7 year old group, the latency of p1 and n1 in the 3-4 year old group was shorter （P<0.05） and the amplitude was higher （P<0.05）, and there was no significant difference in other parameters （P>0.05）. There was no statistical difference in threshold, n1, p1 latency, n1-p1 wave interval, n1-p1 amplitude, and amplitude asymmetry ratio of BCV-cVEMP between the two groups （P>0.05）. Conclusion:ACS-cVEMP and BCV-cVEMP can be elicited in most preschool children, and cVEMP is a feasible method to detect vestibular function in children.
