良性发作性变位性眩晕经颗粒复位治疗后残留症状分析

Analysis of residual dizzy symptoms after successful particle repositioning maneuver in patients with benign paroxysmal positional vertigo

目的观察良性阵发性变位性眩晕(BPPV)经颗粒复位治疗成功后残留头晕症状的特点,并分析可能的相关因素。方法回顾性分析486例BPPV患者的临床特征,在颗粒复位治疗成功后对患者随访3个月,观察残留头晕症状的特点和持续时间,分析相关因素。结果 486例患者中,男性167例(34.4%),女性319例(65.6%),平均年龄(56.9±12.9)岁,平均病程(9.1±8.4)d。其中,281例(57.8%)患者在颗粒复位成功后残留头晕症状,平均持续时间为(27.27±23.32)d(2～90d)。女性、病程长及复位次数≥3次者易残留头晕症状。结论尽早及有效的颗粒复位治疗可减少残留头晕症状的发生。

Objective To observe the characteristics and possible relevant factors of residual dizzy symptoms in patients with benign paroxysmal positional vertigo （BPPV） after successful particle repositioning maneuver.Methods The clinical characteristics of 486 patients with BPPV were retrospectively analysed.Patients were followed up for 3 months after successful particle repositioning maneuver,the characteristics and duration of BPPV of residual dizzy symptoms were observed,and the relevant factors were analysed.Results Among the 486 patients,167（34.4%） were males and 319 （65.6%） were females,with the mean age of （56.9±12.9） years and mean disease duration of （9.1±8.4） d.Two hundred and eight-one patients （57.8%） had residual dizzy symptoms after successful particle repositioning maneuver,and the symptoms lasted for （27.27±23.32） d （2 to 90 d）.The factors of female gender,longer disease duration and number of repositioning therapy ≥3 were significantly associated with residual dizzy symptoms.Conclusion Prompt diagnosis and effective particle repositioning maneuver can reduce the incidence of residual dizzy symptoms in patients with BPPV.
