The aim of this study was to investigate the electronystagmographic findings in patients with benign paroxysmal positional vertigo. A retrospective review of the records of 168 patients with this disease during the past 3 years was performed. Epidemiological data and results from the audiological and neuro-otologic workup, including electronystagmography, were recorded. One hundred fifty-one patients had involvement of the posterior canal, 14 of the horizontal canal, and 3 of the anterior canal. Seventy-two patients (42.8%) had abnormal findings on the caloric tests. Thirty-seven of them (22%) had canal paresis and 23 (13.7%) had directional preponderance, whereas in 12 patients (7.1%) both unilateral weakness and directional preponderance were found. Finally, 21 patients (12.5%) had spontaneous nystagmus. It may be thus concluded that electronystagmographic abnormalities are quite common in patients with benign paroxysmal positional vertigo. Their presence may be explained according to several mechanisms, which are further discussed herein.
本研究的目的是调查良性阵发性位置性眩晕患者的眼震电图检查结果。对过去3年中168例患有该病的患者的记录进行了回顾性分析。记录了流行病学数据以及听力和神经耳科学检查的结果，包括眼震电图检查结果。151例患者后半规管受累，14例水平半规管受累，3例前半规管受累。72例患者（42.8%）冷热试验结果异常。其中37例（22%）存在半规管轻瘫，23例（13.7%）存在方向优势，12例患者（7.1%）同时存在单侧眼震减弱和方向优势。最后，21例患者（12.5%）存在自发性眼震。因此可以得出结论，眼震电图异常在良性阵发性位置性眩晕患者中相当常见。其存在可根据多种机制进行解释，本文将进一步讨论这些机制。
