- Abstract
- Background and Objectives: Since the liberated otoconia from the degenerated utricle has been postulated as the cause of the benign paroxysmal positional vertigo (BPPV), the relationship of the utricular function and the generation of BPPV have been studied. In addition, abnormal bone metabolism and vascular risk factors resulting insufficient circulation to utricle has been reported to be related to the utricular degeneration in BPPV. We investigated the relationship between the vascular risk factors, bone mineral density (BMD) and recurrence for the BPPV and otholith function tests of BPPV. Materials and Methods:Consecutive patients 84 with BPPV were recruited in a dizziness clinic. Caloric test, ocular vestibular evoked myogenic potentials (oVEMPs) were tested in all the patients in acute phase of BPPV. At the same time, vascular risk factors and BMD were performed. Vascular risk factors were history of hypertension, diabetes mellitus, hyperlipidemia and ischemic heart disease. All the data were analyzed for the relationship between abnormal results of vestibular function tests and the risk factors. Results: Patients 58 (69%) showed abnormal cervical VEMPs that were related to decreased bone density, having more than one vascular risk factor, and older age (>55 years). Abnormal oVEMPs were showed in 53patients (63%) that were related to older age and vascular risk factors, but not statistically related to bone mineral density. Caloric tests failed to show any statistically significant results. Conclusion: We found abnormal results of cVEMPs and oVEMPs is related to the BMD, vascular risk factors and age.
VEMPs could be used for the demonstration of presumptive otolith degeneration in BPPV.
