OBJECTIVE
To study the potential role of subjective visual vertical (SVV) as a prognostic marker for canalith repositioning maneuver (CRM) in patients with posterior canal benign paroxysmal positional vertigo (PC-BPPV) for the Indian population.
METHODS
SVV was examined in 30 patients with PC-BPPV before and after canalith repositioning maneuver and after complete resolution of PC-BPPV. Study parameters included the mean of 10 angular tilt readings and direction of deviation, which were compared before and after CRM and following complete resolution of PC-BPPV.
RESULTS
The angle of SVV tilt was greater and deviated towards the affected ear before CRM in all patients, which decreased significantly shortly after CRM and continued to decrease after complete resolution of PC-BPPV (p < 0.0001).
CONCLUSIONS
SVV can be used to test utricular dysfunction in PC-BPPV. The angle of tilt improves in response to CRM, which may be used as a prognostic marker in patients with PC-BPPV receiving CRM.
目的
研究主观视觉垂直（SVV）作为印度人群后半规管良性阵发性位置性眩晕（PC-BPPV）患者耳石复位手法（CRM）预后标志物的潜在作用。
方法
对30例PC-BPPV患者在进行耳石复位手法前后以及PC-BPPV完全缓解后进行SVV检查。研究参数包括10次角度倾斜读数的平均值和偏差方向，在CRM前后以及PC-BPPV完全缓解后进行比较。
结果
所有患者在CRM前SVV倾斜角度更大且偏向患侧耳，在CRM后不久显著减小，并在PC-BPPV完全缓解后继续减小（p < 0.0001）。
结论
SVV可用于检测PC-BPPV患者的椭圆囊功能障碍。倾斜角度随CRM而改善，这可作为接受CRM的PC-BPPV患者的预后标志物。
