ABSTRACT
OBJECTIVES:
We aimed to assess the clinical significance of spontaneous nystagmus (SN) in horizontal semicircular canal benign paroxysmal positional vertigo (HC-BPPV).METHODS:
Twenty-four patients who were diagnosed with HC-BPPV in Eulji University Hospital from January 2015 to December 2016 were recruited. Various bed-side examinations including SN in both sitting and supine position, head roll test, and bithermal caloric test were evaluated. The number of canalith repositioning maneuvers were counted in all patients.RESULTS:
SN was observed in 18.2% of geotropic HC-BPPV and 38.5% of apogeotropic HC-BPPV, respectively. There was no significant difference between presence of SN and the direction of initial nystagmus (p=0.386, 2-tailed Fisher exact test). The mean number of otolith repositioning maneuvers in patients with SN was 3.29±1.799 and this was significantly higher than in patients without SN (1.76±0.831) (p=0.009). Although the mean number of repositioning maneuver in patients in apogeotropic HC-BPPV and SN (3.80±1.924) tended to be higher than those who were diagnosed with apogeotropic HC-BPPV without SN (1.88±1.991) (p=0.035), the post hoc analysis with Bonferroni correction revealed that it was not significant because it was higher than the adjusted p-value (p=0.017). The initial direction of nystagmus was changed into the opposite direction in 29.17% of patient. However, this change was not different according to presence of SN (p=0.374, 2-tailed Fisher exact test).CONCLUSIONS:
The presence of SN in HC-BPPV may be associated with lower treatment response. In particular, cautions are needed in patients with apogeotropic HC-BPPV.
