Abstract:
OBJECTIVE To explore the difference of vestibular damage between sudden deafness and vestibular neuritis.METHODS Patients in otolaryngology head and neck surgery eenterin PLA general hospital from February 25 in 2016 to July 20 in 2016 were included in this research.Among these patients,55 cases were diagnosed as sudden deafness group,including 39 cases With vertigo.And other 46 cases were diagnosed as vestibular neuritis.Vestibular bithermal caloric test,head impulse test(head impulse test,HIT),cervical vestibular evoked myogenic potentials(cervical vestibular evoked myogenic potential,cVEMP),ocular vestibular evoked myogenic potentials(ocular vestibular evoked myogenic potential,oVEMP) were performed to evaluate their vestibular function and were compared.RESULTS The abnormal rate of vestibular bithermal caloric test in sudden deafness group 25.45％,and 97.82％ in vestibular neuritis group.There was significant difference between two groups(x2=54.01,P＜0.001).HIT:the abnormal ratein sudden deafness groupwas 9.09％ and 32.61％ in vestibular neuritis group,there was significant difference between two groups(x2=8.72,P=0.003).VEMP:the abnormal rate of cVEMP in sudden deafness group was 69.10％ and 43.47％ in vestibular neuritis group,there was significant difference between two groups(x2=6.72,P=0.010).But the abnormal rate of oVEMP in sudden deafness group was 54.55％ and 63.04％ in vestibular neuritis group,and there was not statistically significant difference between two groups(x2=0.745,P=0.388).CONCLUSION The vestibular damage of sudden deafness with vertigo was more likely involved with saccule and inferior vestibular nerve,more close to the nerve terminal,and the injury was in a low frequency range;but the vestibular damage in vestibular neuritis was wider,and the injury involved a full band,the damaged part may be higher.
