Objective To investigate whether mechanical vibrational energy from using an electric toothbrush may cause an increase in the incidence of benign paroxysmal positional vertigo (BPPV) and prevent successful treatment of BPPV with canalith repositioning procedure. Methods This was a retrospective study conducted at an otolaryngology private practice. A survey of 111 patients who were diagnosed with BPPV in an otolaryngology practice between May 2012 and January 2017 was conducted using a questionnaire that included questions regarding demographics, inner ear pathology, treatment method, and use of an electric toothbrush. The results were recorded and compared using a chi-square test of analysis or Fisher's exact test. Results Overall, 47 (42.3%) of the 111 BPPV patients used an electric toothbrush, whereas 64 of the 111 (57.6%) patients did not. Six (12.7%) of the 47 patients experienced dizziness with electric toothbrush use. Of the 47 patients using an electric toothbrush, 33 (70.2%) had a resolution of symptoms after Epley treatment, whereas 14 (23.4%) of 47 patients did not. Of the 64 patients who did not use an electric toothbrush, 15 (23.4%) did not have resolution after Epley treatment. Of the 47 patients using an electric toothbrush, 6 (12.8%) had a recurrence of BPPV diagnosed in the office, whereas 41 (82.2%) did not. Seven (10.9%) of those who did not use an electric toothbrush had a recurrence of BPPV, whereas 57 (89.1%) of the 64 patients did not. These results were not statistically significant (p = 0.77). Conclusions This study suggests that the mechanical vibrations from electric toothbrush use do not have an association with recurrent BPPV. The results align with some publications demonstrating that vibrations in the head and neck area from the use of an electric toothbrush can initiate dizziness; however, it does not appear that this modality of vibration is significant for inducing recurrent BPPV.
目的 探讨使用电动牙刷产生的机械振动能量是否会导致良性阵发性位置性眩晕（BPPV）的发病率增加，并妨碍通过半规管结石复位术成功治疗BPPV。方法 这是一项在耳鼻喉科私人诊所进行的回顾性研究。使用一份问卷对2012年5月至2017年1月间在一家耳鼻喉科诊所被诊断为BPPV的111名患者进行了调查，问卷内容包括人口统计学、内耳病理学、治疗方法以及电动牙刷的使用情况等问题。使用卡方分析检验或费舍尔精确检验记录并比较结果。结果 总体而言，111名BPPV患者中有47名（42.3%）使用电动牙刷，而111名患者中的64名（57.6%）未使用。47名患者中有6名（12.7%）在使用电动牙刷时出现头晕。在47名使用电动牙刷的患者中，33名（70.2%）在进行Epley治疗后症状得到缓解，而47名患者中的14名（23.4%）未缓解。在64名未使用电动牙刷的患者中，15名（23.4%）在Epley治疗后未缓解。在47名使用电动牙刷的患者中，6名（12.8%）在诊所被诊断为BPPV复发，而41名（82.2%）未复发。64名未使用电动牙刷的患者中有7名（10.9%）BPPV复发，而64名患者中的57名（89.1%）未复发。这些结果无统计学意义（p = 0.77）。结论 本研究表明，使用电动牙刷产生的机械振动与复发性BPPV无关。该结果与一些表明使用电动牙刷导致头颈部区域振动可引发头晕的出版物一致；然而，这种振动方式似乎对诱发复发性BPPV并不重要。
