目的 分析良性阵发性位置性眩晕(耳石症)患者复位成功后残留症状的临床特点及其可能的影响因素。方法 通过对本院收集的37例后半规管良性阵发性位置性眩晕患者、28例水平半规管良性阵发性位置性眩晕患者，12例混合半规管(同侧水平半规管合并后半规管)良性阵发性位置性眩晕患者采用SRM-IV型BPPV诊疗系统进行复位，收集复位成功后出现残留症状的临床特点及其相关影响因素。结果 77例良性阵发性位置性眩晕患者经明确诊断及成功复位后，残留症状的发生率为48.1%(37/77)，其中头晕者占27%(10/37)，不稳者占16.2%(6/37)，颈部不适者占21.7%(8/37)，合并两种残留症状者占32.4%(12/37)，合并三种残留症状者占2.7%(1/37)。残留症状的发生与复位次数有关，而与发病前存在诱发因素(如劳累及睡眠欠佳)、受累半规管、性别、年龄、病程无关。结论 良性阵发性位置性眩晕复位成功后仍有残留症状，主要为头晕、不稳及颈部不适。残留症状的发生与患者所需复位次数有关。
Abstract
Objective To study the clinical characteristics and factors associated with residual symptoms in patients with benign paroxysmal positional vertigo (BPPV) after successful canalith repositioning maneuvers. Methods 37 patients with P-BPPV, 28 patients with H-BPPV, and 12 patients with M-BPPV totaled 77 after successful repositioning maneuvers(SRM-Ⅳ)for benign paroxysmal positional vertigo were recruited in the prospective study.The clinical characteristics and factors associated with residual symptoms were studied.Results Of the 77 patients,37 patients (48.1%) reported residual symptoms after successful repositioning maneuver, including dizziness 27% (10/37), unsteady 16.2% (6/37), neck malaise 21.7% (8/37), two combined residual symptoms 32.4% (12/37), three combined residual symptoms 2.7% (1/37). The number of repositioning maneuvers were associated with an increased risk of residual symptoms.No association was observed between residual symptoms and poor sleeping and tiredness before illness,involved semicircular canal, gender, age, duration of vertigo.Conclusions Residual symptoms after successful repositioning can be observed in the patients with BPPV.The cardinal residual symptoms are dizziness,unsteadiness and neck malaise. The number of repositioning maneuvers are associated with an increased risk of residual symptoms.
