Recurrence of posterior canal benign paroxysmal positional vertigo (PC-BPPV) developed in one-third of patients when followed for an average of 5 years from diagnosis. History of head trauma and Ménière's disease contributed significantly to recurrence (p < 0.05). History of head trauma as an etiologic cause was more frequent in patients with recurrence of PC-BPPV.
To estimate recurrence in the long-term follow-up of patients with PC-BPPV after successful canalith repositioning maneuvers, and to determine which factors contribute to recurrence.
The charts of 118 patients with PC-BPPV were reviewed. Data of patients were recorded from the initial evaluation and treatment. Follow-up was performed at mean of 64 +/- 7.7 months after the initial phase. The Dix-Hallpike maneuver was performed for diagnosis, and all patients were treated by the canalith repositioning maneuver, which was repeated every 3 days until the patients were symptom-free or results of the Dix-Hallpike maneuver were negative.
At diagnosis, the most common etiology was idiopathic in 55 patients (46.6%). Recurrence occurred in 39 of 118 patients (33.1%). Recurrence occurred within the first 2 years in 21 of the 39 patients (53.8%). History of head trauma was a more frequent finding in patients who developed recurrence (12 of 39, 30.8%).
后半规管良性阵发性位置性眩晕（PC-BPPV）患者自诊断起平均随访5年，三分之一患者出现复发。头部外伤史和梅尼埃病是复发的重要因素（p<0.05）。PC-BPPV复发患者中，头部外伤作为病因更为常见。
评估成功进行半规管结石复位术后PC-BPPV患者的长期随访复发情况，并确定哪些因素导致复发。
回顾118例PC-BPPV患者的病历。记录患者初始评估和治疗的数据。在初始阶段后平均64±7.7个月进行随访。采用Dix-Hallpike手法进行诊断，所有患者均接受半规管结石复位治疗，每3天重复一次，直至患者症状消失或Dix-Hallpike手法结果为阴性。
诊断时，最常见的病因是特发性，共55例（46.6%）。118例患者中有39例（33.1%）复发。39例复发患者中，21例（53.8%）在最初2年内复发。复发患者中头部外伤史更为常见（39例中有12例，30.8%）。
