Background and Objectives : This study aimed to investigate whether benign paroxysmalpositional vertigo (BPPV) accompanied by temporal bone fracture would be more resistant tocanalith repositioning procedures (CRPs) than idiopathic BPPV.
Subjects and Method ; Seventy-eight patients with BPPV were included in this study.
Among them, 13 patients had temporal bone fractures and 65 had no temporal bone fractures.
To identify the factors related to the number of CRPs performed until the remission of BPPV,sex, age, the presence of temporal bone fracture, hypertension, diabetes, dyslipidemia or osteopenia,BPPV affected side, and the type of affected semicircular canal were analyzed usingthe univariable regression analysis. Thereafter, the multivariable regression analysis was performedusing only the variables that had a p-value of 0.2 or less in the univariable analysis.
Results : In the univariable analysis, temporal bone fracture, diabetes mellitus, and BPPVside showed relatively significant association with the number of CRPs (p<0.2). In the multivariableanalysis, only temporal bone fracture showed a significant association with the numberof CRPs (p=0.043, β=0.532, 95% CI: 0.017-1.046).
Conclusion : The major finding of this study is that BPPV, accompanied by temporal bonefracture, precipitated more resistance to CRPs than idiopathic BPPV did. Thus, patients withtemporal bone fracture might need more intensive examination and treatment for BPPV thanthose without temporal bone fracture.
