Effects of postural restriction after modified Epley maneuver on recurrence of benign paroxysmal positional vertigo

Objective

In the present study, we calculated the success rate of the modified Epley maneuver and determined the effectiveness of post-maneuver positional restriction in terms of the prevention of early and late recurrence.

Methods

The present study was conducted on 78 patients who had unilateral benign paroxysmal positional vertigo (BPPV) of the posterior semicircular canal (SCC) and who were treated in the Otorhinolaryngology Department of Susehri State Hospital. The Dix–Hallpike test was performed on all patients. After the involved canal was identified using this test, we guided patients through the modified Epley repositioning maneuver. A maximum of two maneuvers were performed in the same session. The patients were randomly divided into two groups. One group was not advised any positional restriction, while the second group was advised positional restriction for 10 days after the procedure. Recurrences during 1–90 days after the treatment were noted as early recurrences, while those that occurred after 90 days were noted as late recurrences.

Results

In the restriction group (n = 39), repositioning was successful after a single maneuver in 32 (82.05%) patients and after two maneuvers in 5 (12.8%) patients. Repositioning failed in two (5.1%) patients. In the non-restriction group (n = 39), repositioning was successful after a single maneuver in 31 (79.4%) patients and after two maneuvers in 6 (15.3%) patients. Repositioning failed in two (5.1%) patients. Thus, the success rate was 94.8% in each group. Early recurrence occurred in 3 (8.1%) of 37 patients in the restriction group and 2 (5.4%) of 37 patients in the non-restriction group (p > 0.05). Late recurrence occurred in 5 (13.5%) of 37 patients in both the restriction and non-restriction groups (p > 0.05).

Conclusion

Postural restriction after a canalith repositioning procedure does not improve procedural success or decrease early and late recurrence rates. However, the number of patients was too small to detect a difference between both treatment groups.     

Natural course of positional vertigo in patients with apogeotropic variant of horizontal canal benign paroxysmal positional vertigo

Objective

The purpose of this study was to assess the natural course of positional vertigo in patients with the apogeotropic variant of horizontal canal type of benign paroxysmal positional vertigo (AH-BPPV), which is reported to be more refractory to physiotherapy than the geotropic variant of horizontal canal type of BPPV (GH-BPPV).

Methods

14 patients with AH-BPPV treated without physiotherapy were asked to visit the hospital every 2 weeks. At every follow-up visit, they were interviewed and positional nystagmus was assessed. After the disappearance of positional nystagmus, patients were asked about the time of cessation of the positional vertigo. Thus, the primary outcomes were evaluated by the self-reported onset and remission of positional vertigo. The time course of remission of positional vertigo was then calculated.

Results

The average and median period from the onset to natural remission of positional vertigo in patients with AH-BPPV was 13 and 7 days, respectively.

Conclusion

We have already reported that the average and median period from the onset to natural remission of positional vertigo in patients with GH-BPPV was 16 and 7 days, respectively (Imai et al., 2005 [8]). Thus, the natural course of AH-BPPV is not as refractory as that of GH-BPPV.

A cupulolith repositioning maneuver in the treatment of horizontal canal cupulolithiasis

Objective

We evaluated outcomes and their significance of a new treatment method for horizontal canal cupulolithiasis that could be applied regardless of the side of the cupula where otoliths are attached.

Methods

Consecutive 78 patients who showed persistent apogeotropic horizontal canal positional vertigo (horizontal canal cupulolithiasis) were enrolled, and they were treated with the new cupulolith repositioning maneuver.

Results

Horizontal semicircular canal cupulolithiasis was alleviated in 97.4% of patients, after an average of 2.1 repetitions of the maneuver. Otoliths were suspected to be attached to the canal side of the cupula in 30 cases and the utricular side in 44 cases.

Conclusion

The cupulolith repositioning maneuver is an effective method for treating horizontal canal cupulolithiasis. It may also provide an insight into the side of the cupula where otoliths are attached.     

The Epley maneuver for the treatment of benign paroxysmal positional vertigo

In recent years, different forms of physical therapy have been proposed for the treatment of benign paroxysmal positional vertigo (BPPV). These mainly consist of maneuvers aiming to reposition and disperse free-floating endolymph particles in the posterior semicircular canal. We report our experience with one of these procedures, the Epley maneuver (EM), in treating 30 cases of BPPV. Twenty-six patients (87%) were cured, while four (13%) did not respond to treatment. These results are similar to those reported in the literature for the EM and the Sémont maneuver.     

The canalith repositioning maneuver in patients with benign positional vertigo

The canalith repositioning maneuver (CRM), as defined by Epley, can be an effective treatment for benign paroxysmal positional vertigo (BPPV). The staff at Başkent University’s Ear Nose and Throat Clinic performed CRM on 68 cases of canalithiasis in 64 BPPV patients from June 1996 to August 1997. Symptoms resolved after the first session in 49 patients (72%) and after the second session in 11 cases (16.2%). It was necessary to repeat the maneuver three times in two cases (2.9%) and four times in one patient (1.5%). Discounting three patients who were lost to follow-up, only two patients in our study did not respond to CRM treatment. There was no co-existing pathology found in all but two of the patients studied. Our experience indicates that unless there is no response to CRM or there is suspicion of an incorrect diagnosis, it is not necessary to perform diagnostic studies routinely for differentiating other neuro-otologic disorders prior to using CRM in BPPV patients diagnosed by the Dix-Hallpike test.

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.     

水平半规管良性阵发位置性眩晕的诊治

目的探讨水平半规管良性阵发位置性眩晕（horizontalcanalbenignparoxysmalpositionalvertigo,HC-BPPV）的诊治方法。方法回顾分析1996年7月～2000年3月间南京医科大学第一附属医院耳鼻咽喉科诊治的9例HC-BPPV患者的临床资料。对所有患者全面采集病史,行纯音听阈测试和耳神经学检查,常规施行仰卧侧头位试验和Dix-Hallpike试验,并按Barbecue翻滚法行耳石复位治疗。结果本病以头位改变所诱发的短暂旋转性眩晕为特征,常见诱发体位为床上翻身（9/9例）和转头（5/9例）。仰卧侧头位试验可诱发水平向地性眼震,无潜伏期和疲劳性。采用Barbecue翻滚法治疗后全部患者症状立刻消失,随访4～15个月无复发。结论根据典型表现和体位试验结果,可明确区分水平半规管性和后半规管性BPPV以及其他原因引起的眩晕。Barbecue翻滚是治疗HC-BPPV有效的方法。     

顽固性良性阵发性位置性眩晕的发病机制及治疗

目的 回顾性分析我科门诊及住院患者中顽固性良性阵发性位置性眩晕的患者,分析发病因素及治疗手段,为顽固性良性阵发性位置性眩晕的发病机理及治疗提供新思路.方法 收集2010年1月-2010年12月我科门诊诊断为顽固性良性阵发性位置性眩晕的患者16人,分析发病因素、治疗手段及预后.结果 16例患者经手法复位、体位训练及药物辅助治疗后,眩晕症状基本消失,随访半年未再发作.结论 顽固性良性阵发性位置性眩晕发病机制可能与内耳缺血、运动及活动减少有关,我们采用保守治疗的方法,疗效满意.     

良性阵发性位置性眩晕患者复位后残余症状的干预策略:单中心随机对照试验

目的比较不同干预策略处理良性阵发性位置性眩晕(benign paroxysmal positional vertigo, BPPV)复位成功后残余症状的临床疗效。方法采用平行、随机对照试验设计,2019年1—7月期间复旦大学附属眼耳鼻喉科医院收治的129例BPPV复位后有残余症状的患者在线完全随机化分至前庭康复组、倍他司汀组及对照组(空白),每组43例。前庭康复组接受为期4周的康复训练;倍他司汀组口服甲磺酸倍他司汀(12 mg/次,每日3次)4周;对照组无特殊处理。入组后4周、8周时随访,主要结局指标为日常活动与社会参与功能,采用前庭活动与参与量表(vestibular activities and participation measure,VAP)测量,次要指标为基于感觉统合试验(sensory organization test, SOT)的平衡功能以及残余症状的持续天数。采用STATA15.0软件进行统计学分析。结果三组患者VAP量表得分随时间推移均呈下降趋势,但前庭康复组下降幅度更为显著。分组比较,前庭康复组与对照组差异有统计学意义(B=-3.88,χ2=18.29,P<0.01);倍他司汀组与对照组差异无统计学意义(B=-0.96,χ2=1.16,P=0.28)。三组患者平衡功能随时间呈现恢复趋势,组间差异无统计学意义(χ2=1.37,df=2,P>0.05);前庭康复组和倍他司汀组残余症状持续时间的中位数均为14 d,对照组为19 d,三组间差异无统计学意义[Log-rank (Mantel-Cox)test;χ2=1.82,df=2,P=0.40]。结论前庭康复可以显著改善BPPV复位后残余症状患者的日常活动与社会参与功能,对缩短残余症状持续时间和促进平衡功能恢复的效果尚不确定。

水平半规管良性阵发性位置性眩晕的诊断

目的探讨水平半规管良性阵发性位置性眩晕（BPPV）的诊断。方法自2003年1月至2006年9月，本眩晕中心共确诊为水平半规管BPPV（HSC BPPV）患者46例。诊断依据为典型的病史及用红外视频眼震电图仪记录患者在Dix—Hallpike试验和滚转试验中的眼震结果，并排除其他疾病。研究HSC BPPV的眼震特点。结果441例诊断为BPPV患者中，46例（10．43％）为水平半规管BPPV。其中38例（82．61％）为单侧病变，5例（10．87％）患者合并同侧后半规管病变，3例（6．52％）为双侧病变。35例患者通过两种试验诱发出水平眼震，11例患者仅通过滚转试验诱发出水平眼震。25例患者眼震方向向地，13例患者眼震方向背地，3例患者眼震方向不固定，5例患者各种手法诱发出同一方向的眼震。29例患者在双侧手法中出现眼震，17例患者在一侧手法中出现眼震。结论HSC BPPV眼震为完全水平性且多为快相向地。通常受累耳在双侧手法中均可出现眼震，以向患侧为重。一侧水平半规管和后半规管可同时受累。滚转试验在HSC BPPV检查中比Dix—Hallpike试验更加敏感。Dix—Hallpike试验结合滚转试验可使更多的HSCBPPV患者得到确诊．     

Physical treatment of horizontal canal benign positional vertigo

In recent years many methods of physical therapy have been proposed for the treatment of benign paroxysmal positional vertigo due to otolithic debris in the horizontal semicircular canal. All these methods have attempted to promote displacement of debris from the canal to the utricle. This paper reports our experiences with maneuvers advocated by Lempert and Vannucchi et al. Eighteen patients suffering from benign paroxysmal positional vertigo of the horizontal canal were evaluated in the present study. All seven patients treated with the Vannucchi maneuvers resolved their vertigos. Ten of the remaining patients were managed with Lempert's maneuver and responded successfully. The physical therapy used failed in only one patient. Current experience has shown that both maneuvers are particularly valid and efficacious.     

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.     

水平半规管良性阵发性位置性眩晕的临床特点
