Abstract
Background: Benign paroxysmal positional vertigo (BPPV) is the most common peripheral vestibular disorder. Refractory cases persist despite ≥3 repositioning maneuvers over 6 months.
Objective: To identify factors influencing bilateral posterior semicircular canal occlusion (BPCO) efficacy in refractory BPPV.
Methods: A retrospective study included 120 refractory BPPV patients undergoing BPCO. Patients were divided into Group A (successful outcomes, n = 84) and Group B (suboptimal outcomes, n = 36) based on postoperative DHI reduction (≥50% vs. <50%).
Results: Group B had a higher mean age (69.85 ± 4.15 vs. 62.28 ± 3.64 years, p =.012), longer disease duration (≥1 year: 30.56% vs. 10.73%, p < .01), and more bilateral BPPV (16.67% vs. 5.96%, p < .01). At 6 months, Group B showed poorer outcomes: higher dizziness handicap inventory (DHI) scores (53.24 ± 5.39 vs. 30.11 ± 2.88), lower SF-36 scores (58.10 ± 5.32 vs. 81.45 ± 6.29), higher recurrence rates (38.89% vs. 7.14%), and more frequent attacks (13.75 ± 3.66 vs. 4.36 ± 1.25/month) (p < .05). Multivariate analysis confirmed age, disease duration, and bilateral BPPV as independent risk factors (p < .01).
Conclusions: Older age (≥65 years), prolonged disease duration (≥1 year), and bilateral BPPV predict poor BPCO outcomes in refractory BPPV. These factors are critical for preoperative decision-making.
背景:良性阵发性位置性眩晕(BPPV)是最常见的外周前庭疾病。尽管在6个月内进行了3次以上的复位,难治性病例仍然存在。目的:探讨影响双侧后半规管闭塞治疗难治性BPPV疗效的因素。方法:回顾性研究120例难治性BPPV患者行BPCO。根据患者术后DHI减少情况(≥50% vs.结果:B组患者平均年龄较高(69.85±4.15岁vs. 62.28±3.64岁,p = 0.012),病程较长(≥1年:30.56% vs. 10.73%, p p p p p),将患者分为A组(成功结果,n = 84)和B组(次优结果,n = 36)。结论:年龄较大(≥65岁),病程延长(≥1年),双侧BPPV预测难治性BPPV预后较差。这些因素对术前决策至关重要。
