Abstract

Objectives
Benign paroxysmal positional vertigo (BPPV) is one of the most common causes of dizziness. Even though the etiology of BPPV has been widely studied, the exact mechanism remains still unclear. One of the possible factors explaining the pathophysiology of BPPV is ischemia of vestibule. In the present study, we have focused on the platelet indices including mean platelet volume (MPV), platelet distribution width (PDW), and platelet crit (PCT) to assess a risk of vestibule ischemia causing BPPV.
Methods
From January 2021 to March 2021, a retrospective review was performed on 39 patients diagnosed with BPPV through vestibular nystagmography. For each platelet indices, a comparative analysis was conducted between the patient group and control group.
Results
There were no significant differences when the platelet, MPV, PDW, and PCT values were compared between the study and control group. Rather, the control group showed higher PDW value than the study group.
Conclusions
Ischemia of vestibule is one of the well-known causes of BPPV, but the current study showed that BPPV cannot be explained by the vestibule ischemia itself. Further studies are needed to identify the potential of ischemia regarding BPPV by approaching with other methods with a large study group.
