管石复位法治疗良性阵发性位置性眩晕的影响因素分析

目的观察管石复位法治疗良性阵发性位置性眩晕的长期效果，探讨影响治疗预后的相关因素。方法回顾性分析59例后半规管良性阵发性位置性眩晕患者治疗和随访结果．并对管石复位法治疗成功的良性阵发性位置性眩晕患者进行多因素COX回归分析。结果59例患者中有54例（91．5％）治愈。治愈的54例患者在随访中有21例（38．9％）复发，其中有10例患者伴有半规管轻瘫。对患者的性别、年龄、发病时间、病因、半规管功能等指标进行多因素分析，只有半规管轻瘫一项指标进入COX模型，说明半规管轻瘫是影响治疗预后的因素。结论半规管轻瘫是影响BPPV患者管石复位法治疗预后的影响因素。

Prognosis factors affecting CRP treatment in benign paroxysmal positional vertigo

Objective To evaluate long-term outcomes of the canalith repositioning(CRP) maneuver for benign paroxysmal positional vertigo(BPPV) and to identify factors affecting the outcomes. Methods There were 59 BPPV patients who received CRP treatment from 1999 to 2002. To assess the prognostis value of factors including age, sex, causes, history and canal paralysis(CP), COX regression analysis was performed. Results The CRP cured 54 patients. During the follow up period,there were 21 patients (38.9%) with recurrence, 10 of whom suffered from CP. Application the variables in patients to COX regression suggested that CP affected the recurrence rate. Conclusion CP is the variable affecting the prognosis of patients with BPPV who receive CRP treatment.
