ABSTRACT
Objectives Vestibular paroxysmia (VP) of the eighth cranial nerve is characterized by recurrent auditory and vestibular disturbances when a proximal part of the eighth cranial nerve is continuously pressed by a vessel. A detailed history and several ancillary diagnostic tools, such as tinnitogram, caloric test, auditory brainstem response (ABR) and MRI, are used for diagnosis of VP. Among them, although Møller’s criteria using ABR is a simple method, the previous study is insufficient. Therefore, this study aimed to evaluate ABR’s diagnostic value of VP. Methods ABR records of the 14 patients (patient group) who were diagnosed with VP and 45 patients (as control) who were diagnosed with only tinnitus were reviewed retrospectively. We analyzed the differences in Møller’s criteria between two groups. Results Mean age of the patient group was 52.9 and the control group was 55.4. As compared with the control group, there were no significant differences of Møller’s three criteria contents (peak II wave amplitude<33% (35.7% vs. 15.5%, p=0.133), Interpeak latency I-III ≥ 2.3 ms (42.8% vs. 35.5%, p=0.622), Contralateral interpeak latency III-V ≥ 2.2 ms (0% vs. 4.4%, p=1.000) in patient group. Conclusions There was no significant difference of ABR parameters according to the Møller’s criteria between patient and control groups.
