外伤后良性阵发性位置性眩晕手法复位疗效欠佳原因分析

目的探讨外伤后良性阵发性位置性眩晕手法复位疗效欠佳的原因。方法回顾性分析2016年12月—2018年12月南华大学附属第二医院眩晕门诊确诊的外伤后良性阵发性位置性眩晕患者186例,将其设为观察组,选取同期确诊的相同例数特发性良性阵发性位置性眩晕患者为对照组,两组患者经耳石复位后1月复查,比较两组疗效;此外对观察组中疗效欠佳者的年龄、既往疾病、睡眠状态、受伤部位等资料进行分析,寻找外伤后BPPV复位疗效欠佳的原因。结果观察组较对照组复发率明显增高(P<0.01);观察组中年龄≥60岁、高血压、糖尿病、冠心病、脑血管病、头部外伤及睡眠障碍患者耳石复位疗效欠佳(P<0.01)。结论外伤后良性阵发性位置性眩晕复发较特发性良性阵发性位置性眩晕明显增高,除外伤外,年龄≥60岁、既往心脑血管疾病、头部外伤及睡眠障碍等也是其高危因素。

良性阵发性位置性眩晕的临床分析

目的探讨良性阵发性位置性眩晕的临床特征。方法回顾160例确诊BPPV患者,分析其临床资料。结果BPPV发病年龄为7-82岁,好发年龄段均为50—70岁,男女比例为0．68：1。发生于后半规管的BPPV为113例（70．6％）,水平半规管为21例（13．1％）,有26例（16．3％）为同时发生于后半规管和外侧半规管。47例水平半规管BPPV中,33例（70．2％）为半规管耳石,14例（29．8％）为壶腹嵴顶耳石。确诊患者中,有98例（61．3％）为首次发作,有49例（30．6％）为复发,或者有明确的类似发作病史。13例（8．1％）曾有眩晕发作,但具体发病特征不明确。对P—BPPV以Epley复位,1周后复查有效率为81．4％（92／113）。半规管型H—BPPV以Lempert法复位,有效率为72．7％（24／33）。壶腹嵴顶型H—BPPV采用强迫体位（健侧卧位）治疗,1周后复查有38．5％（5／13）转为半规管型,以Lempert法复位奏效。随访1月有12例复发（9例P—BPPV和3例H—BPPV）。结论BPPv在各年龄段均有发作,通过患者的发病特征和详细的神经耳科学检查可以做出诊断。根据不同类型进行复位治疗可以取得较好的疗效。

慢性良性阵发性位置性眩晕研究进展

良性阵发性位置性眩晕是最常见的外周性前庭疾病,它具有较高的患病率和复发率,大部分患者经手法复位治疗后效果较好。然而,有一小部分患者经过多次复位治疗后仍无法治愈。近年来,已有专家学者提出慢性良性阵发性位置性眩晕的概念,尽管此概念目前存在一定的争议,但此类患者确实存在,且国内外学者对此类患者认识不足,缺乏有效的治疗手段。本文将从慢性良性阵发性位置性眩晕的定义、诊断标准、机制及临床干预等方面进行综述。     

病程对后半规管良性阵发性位置性眩晕疗效的影响

目的探究病程是否会影响后半规管良性阵发性位置性眩晕（PC BPPV）患者的疗效。方法收集2009年10月~2017年12月确诊的428例原发性PC BPPV,其中男155例,女273例;年龄16~89岁,中位年龄53岁;病程0.5 d至7年,中位病程7 d。按照1周、1个月、半年为时间节点,将患者分为短期组、中期组、中长期组及长期组。并经Epley或李氏复位法治疗的患者,记录患者治疗3 d及治疗1周的疗效,并统计复位治疗的有效率。结果通过手法复位,4组患者治疗后3 d有效率分别为：94.55%（208/220）、90.80%（132/147）、86.27%（44/51）、90.00%（9/10）;治疗1周后有效率分别为：97.73%（215/220）、97.28%（143/147）、96.08%（49/51）、100%（10/10）;两个时间点的治疗效果差异均无统计学意义（P>0.05）。结论BPPV的病程或自愈性并不会引起手法复位的短期疗效,BPPV的自愈性可能与患者的年龄相关。     

Clinical characteristics and treatment outcomes for benign paroxysmal positional vertigo comorbid with hypertension

Conclusions: Patients with BPPV comorbid with hypertension (h-BPPV) tend to receive a delayed diagnosis of BPPV. Comorbidity with hypertension did not influence the efficacy of the repositioning maneuver; however, comorbidity with hypertension was associated with an increased recurrence rate of BPPV.

Objectives: To determine the clinical characteristics and outcomes of h-BPPV, as well as the clinical differences between h-BPPV and idiopathic BPPV (i-BPPV).

Methods: The authors reviewed the medical records of 41 consecutive patients with h-BPPV (the h-BPPV group) from March to December 2014 and 47 patients with i-BPPV (the i-BPPV group) during the same period.

Results: There were no significant differences in age, sex ratio, or the affected side between the h-BPPV and i-BPPV groups. The proportion of patients reporting an initial episode of positional vertigo was significantly lower in the h-BPPV group (51.22% vs 74.47%; p?=?.024). Patients in the h-BPPV group reported a longer median episode duration than did those in the i-BPPV group (60 days vs 15 days; p?=?.017). The results of treatment using repositioning maneuvers were similar between the two groups. At follow-up, 13 patients in the h-BPPV group were diagnosed with recurrent BPPV compared with six in the i-BPPV group (p?=?.031).     

红外视频眼震检查在良性阵发性位置性眩晕诊断的应用

目的探讨眼震视图(VNG)应用于诊断良性阵发性位置性眩晕(BPPV)的价值。方法对50例拟诊BPPV患者,在视频眼动观察记录下完成DIX_Hallpike变位及ROLL滚转试验,判别受累半规管并采取相应手法复位。结果 (1)依据眼震特点和方向判断受累半规管[1]:后半规管(PSC-BPPV)39例,占78%;水平半规管(HSC-BPPV)6例,占12%;前半规管(ASC-BPPV)1例,占2%;2个或2个以上半规管同时受累及4例,占8%;(2)以此为基础选择适当的手法进行复位治疗,1周后随访疗效:痊愈43例,有效6例,无效1例,总有效率98%。结论眼震视图对BPPV患者眼震情况的客观记录,提高了受累半规管的准确判别率,对于良性阵发性位置性眩晕诊断可以提供一种更为客观、精确的方法。     

Epley's canalith-repositioning manoeuvre for benign paroxysmal positional vertigo

The efficacy of the Epley's canalith-repositioning manoeuvre in the treatment of BPPV was assessed in this prospective study of 62 patients. Patients were selected based on symptoms of positional vertigo and positive Dix-Hallpike's positional test. Patients were divided into two groups; first group comprising 34 patients underwent Epley's manoeuvre alone where as the other group comprising 28 patients underwent Epley's manoeuvre along with mastoid oscillator. At the end of 1 month patients were assessed subjectively by visual analogue scale (VAS) and objectively by Dix-Hallpike's positional test. On VAS, 85.7% patients had complete resolution of symptoms of BPPV in both the groups. Objectively 88.2% did not have positional nysfagmus after 1 month in first group whereas in the second group 86% had complete response at the end of 1 month of therapy. Follow up of 6 months could be done in 38 patients, out of which 7 (18.4%) had recurrence of their symptom of vertigo and positive Dix-Hallpike's positional test, whereas one patient continued to have no relief by Epley's manoeuvre. There was no difference in subjective and objective parameters even when CRP was performed using mastoid vibrator.     

良性阵发性位置性眩晕伴幽闭恐惧症患者临床特征及诊疗体会

目的 分析良性阵发性位置性眩晕(BPPV)伴幽闭恐惧症患者临床特征,探讨临床诊断治疗的注意事项。方法 回顾性研究48例BPPV伴幽闭恐惧症患者临床资料,对患者一般情况、检查方法、检查次数、治疗次数、疗效、复发率、心理状态及生活质量改善程度进行分析,并与同期50例原发性BPPV患者进行比较。结果 两组患者的总有效率、平均治疗次数、复发率和生活质量得到改善情况差异无统计学意义(P>0.05),两组患者的首次检查确诊率(P=0.019)、社会活动恢复情况(P=0.000)有显著性差异。结论 对于BPPV伴幽闭恐惧症患者,临床建议给予多次裸眼检查或多次复诊观察眼震以明确诊断。BPPV伴幽闭恐惧症患者经治疗后生活质量改善情况好,但幽闭恐惧症患者在治疗后参与社会活动方面受影响,需要给予关注。     

难治性良性阵发性位置性眩晕的临床分析

目的 探讨难治性良性阵发性位置性眩晕(BPPV)的临床特点及治疗。 方法 回顾分析2014年8月至2016年1月诊断为难治性BPPV的13例患者的临床资料,分析其病因相关因素、类型、临床特点及治疗效果。 结果 13例难治性BPPV中,头部外伤为最常见因素,离地性水平半规管BPPV为最常见类型。根据病因积极治疗伴随疾病,正确手法复位治疗,联合Brandt-Daroff康复训练,11例治愈,随访1年无复发;2例无效;1例后半规管、1例水平半规管BPPV,至他院行半规管堵塞术手术治疗,术后效果好。 结论 难治性BPPV可能与头部外伤及突发性聋等疾病相关,首先需根据病因积极治疗伴随疾病,同时采用正确的手法复位治疗,并联合康复训练。治疗后大部分患者疗效好,无效者行半规管堵塞术效果好。     

Spontaneous nystagmus in horizontal canal benign paroxysmal positional vertigo

Objective

Benign paroxysmal positional vertigo of horizontal semicircular canal (HSC-BPPV) is characterized by either geotropic or apogeotropic nystagmus induced by head roll test. Some patients also present with spontaneous nystagmus. The aim of this study is to examine the clinical manifestation of spontaneous nystagmus in HSC-BPPV and evaluate the effect on the treatment outcome.

Patients and methods

Electronystagmography and video eye movement recordings of 125 patients diagnosed as HSC-BPPV were reviewed retrospectively. Presence of spontaneous nystagmus was analyzed and treatment outcome after repositioning therapy was compared.

Results

Overall, spontaneous nystagmus was observed in 19 patients (15.2%) with HSC-BPPV at initial presentation. In canalolithiasis group (n = 64), the treatment outcome did not differ between patients with or without spontaneous nystagmus. However, in cupulolithiasis group (n = 61), patients presenting with spontaneous nystagmus (n = 10) required more repositioning therapy sessions.

Conclusion

The presence of spontaneous nystagmus at initial presentation may implicate poorer treatment outcome in cupulolithiasis HSC-BPPV patients.     

Development of a murine model of traumatic benign paroxysmal positional vertigo: a preliminary study

Conclusion: The results showed a gradual detachment of otoconia in the utricle after a single event of head vibration, possibly explaining the frequent recurrence of BPPV attacks and persistent dizziness after trauma.

Objectives: This study developed a murine model of traumatic BPPV and observed the changes in otoconia detachment over time.

Methods: Six-week-old CBA mice were used in this study. Otoconia detachment was induced by vibrating the head for 2?min. Utricles of mice were harvested from different groups: before the head vibration and 1?day, 1 week, 1 month, and 3 months after vibration application. Using scanning electron microscopy and ImageJ software, the percentage of the intact area of otoconia in the utricle was calculated. Hearing thresholds were compared among the groups.

Results: The mean (±?SD) percentages of the intact area of otoconia in the utricle were 98.1%?±?1.7% before the vibration and 93.6%?±?1.7%, 88.9%?±?5.3%, 78.2%?±?20.9%, and 38.9%?±?24.1% at 1?day, 1 week, 1 month, and 3 months after the vibration, respectively. The percentage decreased significantly over time after the vibration (p?相似文献
