Abstract

Objective: The study aimed to investigate the clinical characteristics of patients with multi-canal benign paroxysmal positional vertigo (MC-BPPV).

Methods: We performed a retrospective analysis of 927 patients with BPPV who were admitted to our hospital between January 1, 2016 and December 31, 2019. The clinical data of all patients were collected. The Dix-Hallpike, straight head-hanging, and supine Roll tests were performed in all patients. The nystagmus was recorded using videonystagmography. The clinical characteristics of patients with MC-BPPV and single canal BPPV (SC-BPPV) was analyzed and compared.

Results: Among 927 patients included, 49 (5.29%) patients had MC-BPPV, 878 (94.71%) patients had SC-BPPV. There were significant differences in the male to female ratio (1:3.90 vs 1:1.81, P < .05), mean age (62.47±12.51 vs 59.04±13.72, P < .05), as well as the ratio of cupulolithiasis to canalithiasis (1:1.45 vs 1:4.78, P < .01) between patients with MC-BPPV and SC-BPPV. The frequency of involvement of PC, HC, and AC were involved for 66 (67.35%), 23 (23.47%), and 9 (9.18%) times, respectively, in patients with MC-BPPV, which were involved in 581 (66.17%), 281 (32.0%), and 16 (1.82%) patients, respectively, in patients with SC-BPPV. No significant difference was found in the frequency of involvement of PC and HC between patients with MC-BPPV and SC-BPPV, while there was significant difference in the frequency of AC involvement between 2 groups (P < .01). Ipsilateral PC-HC-BPPV (n = 18) and bilateral PC-BPPV (n=19) were the most common among patients with MC-BPPV. Twenty-six (53.06%) patients had ipsilateral MC-BPPV, 23 (46.94%) had bilateral MC-BPPV. Of the 26 patients with ipsilateral MC-BPPV, 7 patients combined with unilateral peripheral vestibular disorder.

Conclusion: Patients with MC-BPPV had a significantly older mean age at disease onset and a higher proportion of females compared with patients with SC-BPPV. Cupulolithiasis was more common in MC-BPPV. AC involvement was also much more common in MC-BPPV than in SC-BPPV.

多腔良性阵发性位置性眩晕患者的客观检查结果。

研究目的本研究旨在探讨多管道良性阵发性位置性眩晕（MC-BPPV）患者的临床特征：我们对 2016 年 1 月 1 日至 2019 年 12 月 31 日期间我院收治的 927 名 BPPV 患者进行了回顾性分析。收集了所有患者的临床数据。对所有患者进行了 Dix-Hallpike、直头悬吊和仰卧滚动试验。眼球震颤通过视频眼球震颤成像进行记录。对 MC-BPPV 和单管 BPPV（SC-BPPV）患者的临床特征进行了分析和比较：在纳入的 927 名患者中，49 名（5.29%）患者患有 MC-BPPV，878 名（94.71%）患者患有 SC-BPPV。MC-BPPV和SC-BPPV患者的男女比例（1:3.90 vs 1:1.81，P＜0.05）、平均年龄（62.47±12.51 vs 59.04±13.72，P＜0.05）以及杯状结石与管状结石的比例（1:1.45 vs 1:4.78，P＜0.01）均有明显差异。在 MC-BPPV 患者中，PC、HC 和 AC 的受累频率分别为 66（67.35%）、23（23.47%）和 9（9.18%）次，而在 SC-BPPV 患者中，PC、HC 和 AC 的受累频率分别为 581（66.17%）、281（32.0%）和 16（1.82%）次。MC-BPPV和SC-BPPV患者PC和HC受累的频率无明显差异，而两组患者AC受累的频率有明显差异（P < .01）。MC-BPPV 患者中最常见的是同侧 PC-HC-BPPV（18 人）和双侧 PC-BPPV（19 人）。同侧 MC-BPPV 患者有 26 人（53.06%），双侧 MC-BPPV 患者有 23 人（46.94%）。在26名同侧MC-BPPV患者中，7名患者合并有单侧外周前庭障碍：结论：与SC-BPPV患者相比，MC-BPPV患者的平均发病年龄明显偏大，女性比例更高。杯状结石在 MC-BPPV 中更为常见。MC-BPPV的交流受累也比SC-BPPV常见得多。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
