Abstract：Objective To report video head impulse test(vHIT)and caloric test results in 40 patients with acute vestibular neuritis(VN),and to discuss their correlations with and values in the diagnosis of VN.Methods Data from 40 patients with acute VN admitted to Tangshan Dizziness Diagnosis and Rehabilitation Center from January 2019 to October 2022 were retrospectively analyzed.Based on cerebral palsy(CP)scores,the patients were divided into three groups:i.e.CP>50%(Group A,n=15),25%≤CP≤50%(Group B,n=17),and CP<25%(Group C,n=8).vHIT and dual temperature caloric test results were compared among the groups.Results vHIT indicated more horizontal and anterior semicircular canals involvement than posterior semicircular canals(P<0.001).The rate of positive caloric test was 80.00%.vHIT gain on the side of damaged semicircular canal was the lowest in Group A(P<0.05),followed by Groups B and C in that order(P<0.05).Conclusion The probability of high frequency damage of horizontal and anterior semi-circular canals in VN patients is higher than that of posterior semicircular canals.The higher the CP score in caloric test,the lower vHIT gain in the corresponding horizontal semicircular canal.At the very early stage of VN,there may be low-frequency damage response delay in the horizontal semicircular canal.It is therefore necessary to evaluate semicircular canal functions together with vHIT.
