【摘要】：目的本研究目的是,通过观察坐-卧位眼震(SSPN)在良性阵发性位置性眩晕(BPPV)患者中的临床表现与特征,来评价其临床意义,进而探讨SSPN对良性阵发性位置性眩晕的诊断及治疗策略制定的价值。方法收集200例就诊我科并依据病史及诱发试验诊断为BPPV的病例。所有病例先行坐-卧位试验(SSPT),再行仰卧侧头试验(SRT),最后再行Dix-Hallpike试验(DHT),依据SRT、DHT确定BPPV类型并分为后半规管BPPV组(PSC-BPPV)、水平半规管BPPV组(HSC-BPPV组)、前半规管BPPV组(ASC-BPPV组),统计分析各组SSPN诱发率及特征。结果200例BPPV患者中116例(58.0%)诱发出SSPN,其中PSC-BPPV组136例中72例(52.9%)诱发出SSPN,HSC-BPPV组60例中44例(73.3%)诱发出SSPN,ASC-BPPV组4例中0例(0%)诱发出SSPN。PSC-BPPV组诱发出的SSPN均表现为以眼球上极为标志的,扭转成分向患耳,垂直成分向额侧的垂直扭转性眼震。管石型HSC-BPPV患者41例中28例(68.3%)诱发出SSPN,22例(78.6%)诱发出的SSPN指向健侧,6例(21.4%)诱发出的SSPN指向患侧;嵴顶结石型HSC-BPPV患者19例中16例(84.2%)诱发出SSPN,16例(100%)诱发出的SSPN指向患侧。结论SSPN对不同类型BPPV的诊断意义不同,且试验方法简单,不额外增加患者因诱发试验带来的不良反应,结合SSPN可准确、便捷、高效的判断BPPV受累患侧,为耳石复位提供有效的依据。
[Abstract]:Objective to evaluate the clinical significance of SSPN in patients with benign paroxysmal positional vertigo (BPPV).The value of SSPN in the diagnosis and treatment of benign paroxysmal positional vertigo was discussed.Methods 200 cases of BPPV diagnosed by history and induction test were collected.The induction rate and characteristics of SSPN in each group were analyzed.Results SSPNs were induced in 116 cases of BPPV (58.0%) and 72 cases in PSC-BPPV group (52.9%). (44 cases of 60 cases in PSC-BPPV group (73.3%)) of 4 cases in SSPN.PSC-BPPV group (0 case) induced SSPN in SSPN.PSC-BPPV group were highly marked by eyeball.Torsional component to the ear, vertical component to the frontal side of the vertical torsional nystagmus.In 41 patients with tracheolithiasis type HSC-BPPV, 28 cases (68.3%) induced SSPNN (22 cases, 78.6 cases) (induced SSPN to point to the healthy side (6 cases, 21. 4%)) to the diseased side of SSPN (16 cases (84.2%) of 19 patients with HSC-BPPV with crest stone) induced SSPN pointing to the affected side.Conclusion the diagnostic significance of SSPN for different types of BPPV is different, and the test method is simple, and it does not increase the adverse reaction caused by the induced test. The combination of SSPN and SSPN can accurately, conveniently and efficiently judge the affected side of BPPV.To provide an effective basis for the reduction of otolith.
