Abstract：
BACKGROUND: Benign positional paroxysmal vertigo (BPPV) stands as the commonest cause for vertigo. It accounts for 20% of all cases of vertigo, even with its high prevalence rate it often goes underdiagnosed and undertreated. Development of the consensus document by the Bárány society\'s International Classification of Vestibular Disorders (ICVD)significantly facilitates the diagnosis of BPPV and its variants. This study assesses the utilisation of ICVD criteria for managing BPPV.
METHODS: This is a cross-sectional descriptive study conducted at a tertiary care hospital in Northern India spanning from November 1, 2022, to November 30, 2023. A total of 110 participants diagnosed with BPPV were enrolled consecutively. All participants underwent Dix-Hallpike and supine log roll positional maneuvers. Diagnosis was made based on the history and type of nystagmus seen, and classified as per the ICVD criteria.
RESULTS: Posterior semicircular canalolithiasis (pc-BPPV) accounted for 25.45% of cases and horizontal canal canalolithiasis (hc-BPPV) accounted for 20.91% of cases. Probable BPPV, spontaneously resolved (pBPPVsr) was diagnosed in 16.36% of participants and possible BPPV(pBPPV) was diagnosed in 18.18% of participants. Multiple canal BPPV (mc-BPPV) accounted for 17.27% of cases. One participant was diagnosed with horizontal canal cupulolithiasis and anterior canal canalolithiasis respectively. No participant was diagnosed with posterior canal cupulolithiasis.
CONCLUSIONS: The most common type of BPPV was pc-BPPV followed by hc-BPPV. The affected canal in possible BPPV, can be identified, and appropriate repositioning maneuvers are effective in treating them as well as aids in confirming the diagnosis. The diagnostic clarity provided by ICVD, aids in effective management of BPPV. More studies with larger sample size are required to further validate its clinical utility.

摘要：
背景：良性位置性阵发性眩晕（BPPV）是眩晕的最常见原因。它占所有眩晕病例的20%，即使患病率很高，它也经常被诊断和治疗不足。Bárány协会的国际前庭疾病分类（ICVD）的共识文件的发展极大地促进了BPPV及其变体的诊断。本研究评估了ICVD标准在管理BPPV中的应用。
方法：这是一项横断面描述性研究，在印度北部的一家三级医院进行，时间为2022年11月1日至2023年11月30日。连续纳入110例诊断为BPPV的参与者。所有参与者都进行了Dix-Hallpike和仰卧原木滚动位置操作。根据所见眼球震颤的病史和类型进行诊断，并按照ICVD标准进行分类。
结果：后半规管管结石（pc-BPPV）占25.45％，水平管管结石（hc-BPPV）占20.91％。可能的BPPV,16.36％的参与者诊断为自发缓解（pBPPVsr），18.18％的参与者诊断为可能的BPPV（pBPPV）。多管BPPV(mc-BPPV)占17.27%。一名参与者分别被诊断为水平管管管结石和前管管管结石。没有参与者被诊断为后管管髓结石。
结论：最常见的BPPV类型是pc-BPPV，其次是hc-BPPV。可能的BPPV中受影响的运河，可以识别，和适当的重新定位操作是有效的治疗，以及帮助确认诊断。ICVD提供的诊断清晰度，有助于BPPV的有效管理。需要更多样本量更大的研究来进一步验证其临床实用性。
