Role of cervical vestibular evoked myogenic potential response in identifying vestibular dysfunction

Objectives: To analyse cervical vestibular evoked myogenic potential response parameters in normal volunteers and vertiginous patients. Subjects and methods: A prospective study of 50 normal subjects and 50 patients with vertigo was conducted at Chiang Mai University Hospital, Thailand. Cervical ves...

Hanprasertpong C. Kangsanarak J. Objectives: To analyse cervical vestibular evoked myogenic potential response parameters in normal volunteers and vertiginous patients. Subjects and methods: A prospective study of 50 normal subjects and 50 patients with vertigo was conducted at Chiang Mai University Hospital, Thailand. Cervical vestibular evoked myogenic potential responses were measured using air-conducted, 500-Hz, tone-burst stimuli with subjects in a sitting position with their head turned toward the contralateral shoulder. Results: The mean ± standard deviation age and male:female ratio in the normal (44.0 ± 9.3 years; 12:38) and vertigo groups (44.7 ± 9.8 years; 17:33) were not significantly different. The prevalence of absent responses in the normal (14 per cent) and vertigo ears (46 per cent) differed significantly (p < 0.0001). Other cervical vestibular evoked myogenic potential parameters (i.e. response threshold, P1 and N1 latency, P1-N1 interlatency and interamplitude, inter-ear difference in P1 threshold, and asymmetry ratio) showed no inter-group differences. Conclusion: The absence of a cervical vestibular evoked myogenic potential response is useful in the identification of vestibular dysfunction. However, patients should undergo a comprehensive battery of other vestibular tests to supplement their cervical vestibular evoked myogenic potential response findings. © JLO (1984) Limited 2013. 2014-08-30T02:35:46Z 2014-08-30T02:35:46Z 2013 Conference Paper 00222151 10.1017/S0022215113001655 JLOTA http://www.ncbi.nlm.nih.gov/pubmed/23927833 http://www.scopus.com/inward/record.url?eid=2-s2.0-84884489709&partnerID=40&md5=f2b1bd498d83cfb0283e265e1f7ba49f http://cmuir.cmu.ac.th/handle/6653943832/4185 English
