Horizontal semicircular canal benign paroxysmal positional vertigo(HSC-BPPV) is the second most common type of BPPV. It is difficult to diagnose and treat, which has a serious impact on the prognosis of patients.
To study the clinical features of HSC-BPPV and the influencing factors of residual dizziness (RD).
The clinical data of 358 patients with BPPV were retrospectively collected. The differences between HSC-BPPV and posterior semicircular canal benign paroxysmal positional vertigo (PSC-BPPV) were compared, and the influencing factors of RD after HSC-BPPV repositioning were analyzed.
① Compared with PSC-BPPV, HSC-BPPV had a lower success rate of first repositioning (64.7 75.0%), a higher incidence of RD (57.3 43.8%), and a higher DHI score (40.0 34.0), and the differences were statistically significant ( < .05). ② Logistic regression analysis showed that age ≥60 years, secondary, DHI score, successful first repositioning were the influencing factors for the development of RD after HSC-BPPV repositioning ( < .05).
The diagnosis and treatment of HSC-BPPV is difficult, and RD is prone to occur. Clinicians need to strengthen the training of HSC-BPPV diagnosis and treatment to reduce the occurrence and progression of RD.
水平半规管良性阵发性位置性眩晕（HSC-BPPV）是第二常见的BPPV类型。其诊断和治疗困难，对患者预后有严重影响。
研究HSC-BPPV的临床特征及残余头晕（RD）的影响因素。
回顾性收集358例BPPV患者的临床资料。比较HSC-BPPV与后半规管良性阵发性位置性眩晕（PSC-BPPV）的差异，并分析HSC-BPPV复位后RD的影响因素。
①与PSC-BPPV相比，HSC-BPPV首次复位成功率较低（64.7%对75.0%），RD发生率较高（57.3%对43.8%），DHI评分较高（40.0对34.0），差异有统计学意义（P<0.05）。②Logistic回归分析显示，年龄≥60岁、继发性、DHI评分、首次复位成功是HSC-BPPV复位后发生RD的影响因素（P<0.05）。
HSC-BPPV的诊断和治疗困难，且易发生RD。临床医生需加强HSC-BPPV诊断和治疗的培训，以减少RD的发生和进展。
