Abstract

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.

主观上视垂直在后管良性阵发性位置性眩晕患者中作为后管复位后预后指标的作用

目的研究印度人群后管良性阵发性体位性眩晕(PC-BPPV)患者主观上视垂直(SVV)作为肛管复位操作(CRM)预后指标的潜在作用。方法对30例PC-BPPV患者行导管复位术前后及PC-BPPV完全消退后的ssvv进行检测。研究参数包括10个角度倾斜读数的平均值和偏离方向，比较CRM前后和PC-BPPV完全解决后的结果。结果所有患者术前SVV倾斜角度均较大且偏向患耳，在术后不久SVV倾斜角度明显下降，在PC-BPPV完全消退后继续下降(p <0.0001)。结论ssvv可用于检测PC-BPPV的心室功能障碍。倾斜角度在接受CRM后有所改善，可作为PC-BPPV患者接受CRM的预后指标。

期刊介绍： Journal of Otology is an open access, peer-reviewed journal that publishes research findings from disciplines related to both clinical and basic science aspects of auditory and vestibular system and diseases of the ear. This journal welcomes submissions describing original experimental research that may improve our understanding of the mechanisms underlying problems of basic or clinical significance and treatment of patients with disorders of the auditory and vestibular systems. In addition to original papers the journal also offers invited review articles on current topics written by leading experts in the field. The journal is of primary importance for all scientists and practitioners interested in audiology, otology and neurotology, auditory neurosciences and related disciplines. Journal of Otology welcomes contributions from scholars in all countries and regions across the world.
