Orthotropic nystagmus in predicting the efficacy of treatment in posterior canal benign paroxysmal positional vertigo

ObjectiveTo observe the type of nystagmus in each position of posterior semicircular canal benign paroxysmal positional vertigo (BPPV) after treatment with the Epley maneuver and analyze the relationship between the type of nystagmus in the second and third positions of the Epley maneuver and the effect of treatment. Then, the role of orthotropic nystagmus in predicting the success of posterior semicircular canal BPPV treatment was explored.MethodsTwo hundred seventy-six patients diagnosed with posterior semicircular canal BPPV who were admitted from September 2018 to October 2019 to Zhejiang Hospital were included. All patients were treated with BPPV diagnosis and treatment system (Epley maneuver). During the treatment, we observed and recorded the type of nystagmus in the second and third positions, including the direction and duration of nystagmus. One hour after the first treatment, all patients were evaluated by both the Dix-Hallpike and Roll tests to determine whether the treatment was successful. The difference in the success rate of treatment between different types of nystagmus was compared, and the differences in sensitivity and specificity of orthotropic nystagmus in the second and third positions in predicting the effect of treatment were compared.ResultsAmong the 234 patients who had successful repositioning for the first time, the proportion of orthotropic nystagmus during the third position of the Epley maneuver was 88.9%, which was significantly higher than 23% in the unsuccessful group (42 cases) (P < 0.05) The proportion of patients with reversed nystagmus (4.7% vs 33.3%, P < 0.05) and no nystagmus (6.4% vs 42.9%, P < 0.05) was lower in the successful group than in the unsuccessful group. The proportion of orthotropic nystagmus during the second position of the Epley maneuver was 50.9%, which was also higher than the 19% in the unsuccessful group (P < 0.05). The proportion of reversed nystagmus (13.7% vs 31%, P < 0.05) was lower in the successful group than in the unsuccessful group. Additionally, the proportion of no nystagmus (35.5% vs 50%, P = 0.074) was lower in the successful group than in the unsuccessful group, but the difference was not statistically significant. The sensitivity of orthotropic nystagmus in the third position (88.9%) of the Epley maneuver in predicting the efficacy of treatment was higher than that of orthotropic nystagmus in the second position (50.9%), but there was no significant difference in specificity between the two.ConclusionOrthotropic nystagmus during the Epley maneuver, especially in the third position, has certain value in predicting the efficacy of posterior semicircular canal BPPV repositioning, which is better than its predictive effect in the second position, whereas reversed nystagmus or no nystagmus in the third position is suggestive of unsuccessful repositioning. Therefore, clinicians can carry out individualized treatments based on nystagmus types during repositioning to improve the effect of treatment.     

Benign positional paroxysmal vertigo in the general ear, nose, and throat clinic

Benign positional paroxysmal vertigo is a common disease which may be caused by abnormal movement of utricular debris in the posterior semicircular canal. It is diagnosed by the Dix-Hallpike positional maneuver eliciting vertigo and nystagmus. Treatment generally consists of physical exercises with the Epley or Semont maneuvers. We review 43 consecutive patients diagnosed as BPPV in the last year and treated with physical therapy (Epley maneuvers). Results were very good, with a cure rate of 88.37% (53.5% after a single maneuver). Physical therapy is an effective treatment for BPPV.     

Benign paroxysmal positional vertigo

Benign paroxysmal positional vertigo (BPPV) is characterized by positional vertigo (brief attacks of rotatory vertigo triggered by head position changes in the direction of gravity) and is the most common peripheral cause of vertigo. There are two types of BPPV pathophysiology: canalolithiasis and cupulolithiasis. In canalolithiasis, otoconial debris is detached from the otolithic membrane and floats freely within the endolymph of the canal. In cupulolithiasis, the otoconial debris released from the otolithic membrane settles on the cupula of the semicircular canal and the specific gravity of the cupula is increased. Consensus has been reached regarding three subtypes of BPPV: posterior-canal-type BPPV (canalolithiasis), lateral-canal-type BPPV (canalolithiasis) and lateral-canal-type BPPV (cupulolithiasis). In the interview-based medical examination of BPPV, questions regarding the characteristics of vertigo, triggered movement of vertigo, duration of vertigo and cochlear symptoms during vertigo attacks are important for the diagnosis of BPPV. The Dix–Hallpike test is a positioning nystagmus test used for diagnosis of posterior-canal-type BPPV. The head roll test is a positional nystagmus test used for diagnosis of lateral-canal-type BPPV. When the Dix–Hallpike test is repeated, positional nystagmus and the feeling of vertigo typically become weaker. This phenomenon is called BPPV fatigue. The effect of BPPV fatigue typically disappears within 30 min, at which point the Dix–Hallpike test again induces clear positional nystagmus even though BPPV fatigue had previously caused the positional nystagmus to disappear. For the treatment of BPPV, sequential head movements of patients can cause the otoconial debris in the semicircular canal to move to the utricle. This series of head movements is called the canalith repositioning procedure (CRP). The appropriate type of CRP depends on the semicircular canal in which the otoconial debris is located. The CRP for posterior-canal-type BPPV is called the Epley maneuver, and the CRP for lateral-canal-type BPPV is called the Gufoni maneuver. Including a time interval between each head position in the Epley maneuver reduces the immediate effect of the maneuver. This finding can inform the development of methods for reducing the effort exerted by doctors and the discomfort experienced by patients with posterior-canal-type BPPV during the Epley maneuver.     

Success of the modified Epley maneuver in treating benign paroxysmal positional vertigo.

OBJECTIVE: Benign paroxysmal positional vertigo (BPPV) is a common condition seen by otolaryngologists. The purpose of this study is to determine the ability of the modified Epley maneuver to treat BPPV. STUDY DESIGN: Retrospective review. METHODS: A retrospective chart review of 107 patients diagnosed with BPPV at our institution between March of 1993 and June of 1995. Each patient was diagnosed with isolated BPPV by history and Hallpike-Dix maneuver. There were no other vestibular symptoms or electronystagmogram abnormalities. Patients diagnosed with BPPV received modified Epley maneuvers, were instructed to remain upright for 48 hours, and wore a soft collar for a week. Patients were followed up with repeat Hallpike-Dix maneuvers at 1 to 2 weeks. If symptoms persisted, the maneuver was repeated for up to a maximum of three times, at which point patients were considered to have failed treatment. RESULTS: The average age of patients was 57.8 years old. Thirty percent were male and the right ear was affected in 54%. The posterior semicircular canal was affected in 105 ears. The average patient received 1.23 Epley maneuvers, with a success rate of 93.4%. No successfully treated patients received mastoid vibration. Seven out of 107 patients failed after three Epley maneuvers. Two failure patients had a history of temporal bone fracture. Two failure patients were treated with posterior semicircular canal block surgery. CONCLUSION: The modified Epley maneuver is an excellent treatment for BPPV.     

Efficacy of postural restriction in treating benign paroxysmal positional vertigo

OBJECTIVE: To investigate the efficacy of postural restriction after canalith repositioning in treating benign paroxysmal positional vertigo (BPPV). DESIGN: Prospective trial of patients with postural restriction vs those without postural restriction after treatment. PATIENTS: Patients with classic BPPV and with BPPV without nystagmus were treated using the modified Epley canalith repositioning procedure. Patients were randomly separated into 2 groups. The first group was instructed to wear a cervical collar and to maintain an upright head position for 2 days. The second group had no motion restriction. After 5 days, the patients were followed up and evaluated using the Dix-Hallpike test. RESULTS: In the first group, 56 of 62 ears healed after the first maneuver, and the remaining ears healed after the second. In the second group, 45 of 57 ears healed after the first maneuver, 6 after the second, and 5 (with subsequent postural restriction) after the third (1 ear did not improve). Five patients in the first group and 3 patients in the second group had BPPV without nystagmus; all of these patients healed after a single maneuver. The difference between the 2 groups in the number of maneuvers required for treatment was statistically significant (P<.05). The number of patients who required a third maneuver was significantly higher in the second group (P<.05). CONCLUSIONS: Postural restriction enhances the therapeutic effect of canalith repositioning in the treatment of posterior semicircular canal BPPV. The long-term efficacy of postural restriction in preventing BPPV recurrence has not been demonstrated.     

Effectiveness of treatment techniques in 923 cases of benign paroxysmal positional vertigo

OBJECTIVE: To present treatment effectiveness of 923 consecutive cases of benign paroxysmal positional vertigo (BPPV) using canalith repositioning, liberatory, and log roll maneuvers combined with redistribution exercises. STUDY DESIGN: Retrospective case review. METHODS: Patients presented with either posterior semicircular canal (P-SCC) BPPV or horizontal semicircular canal (H-SCC) BPPV. Diagnosis was based on patient history of transient paroxysmal vertigo and a positive Dix-Hallpike response with either torsional or horizontal nystagmus. Patients with P-SCC BPPV numbered 840, and 83 patients had H-SCC BPPV. In the original study, there were 1,000 patients; however, 77 patients were dropped from the study because of lack of follow-through. Intervention was canalith repositioning, liberatory maneuvers, log roll maneuvers, and redistribution exercises. Patients numbering 607 were treated with canalith repositioning, 233 patients had liberatory maneuvers, and 83 received log roll maneuvers. All patients received redistribution exercises before treatment maneuvers. After intervention, patients were reassessed at 6 months. RESULTS: There were 601 women and 322 men from ages 12 to 94 (median 55) years. The average duration of symptoms before intervention was 30 months. Outcome measures were considered met when symptoms of BPPV had abated and patients demonstrated a negative Dix-Hallpike response. In the repositioning group, 94% of patients were symptom free or improved, 98% in the liberatory maneuver group and 100% in the log roll group. The average number of sessions was three for all groups. Recurrence of symptoms was demonstrated in 140 (16%) patients at 6 months. CONCLUSIONS: Treatment of BPPV can be effective using either repositioning, liberatory, or log roll maneuvers in combination with redistribution exercises.     

Diagnosis and treatment of the short-arm type posterior semicircular canal BPPV

IntroductionThe Epley maneuver is useful for the otoconia to return from the long arm of the posterior semicircular canal into the utricle. To move otoconia out of the posterior semicircular canal short arm and into the utricle, we need different maneuvers.ObjectiveTo diagnose the short-arm type BPPV of the posterior semicircular canal and treat them with bow-and-yaw maneuver.Methods171 cases were diagnosed as BPPV of the posterior semicircular canal based on a positive Dix–Hallpike maneuver. We first attempted to treat patients with the bow-and-yaw maneuver and then performed the Dix–Hallpike maneuver again. If the repeated Dix–Hallpike maneuver gave negative results, we diagnosed the patient with the short-arm type of BPPV of the posterior semicircular canal and considered the patient to have been cured by the bow-and-yaw maneuver; otherwise, probably the long-arm type BPPV of the posterior semicircular canal existed and we treated the patient with the Epley maneuver.ResultsApproximately 40% of the cases were cured by the bow-and-yaw maneuver, giving negative results on repeated Dix–Hallpike maneuvers, and were diagnosed with short-arm lithiasis.ConclusionThe short-arm type posterior semicircular canal BPPV can be diagnosed and treated in a convenient and comfortable manner.     

Benign paroxysmal positional vertigo: 10-year experience in treating 592 patients with canalith repositioning procedure

OBJECTIVE: To assess the long-term efficacy of canalith repositioning procedure (CRP) in the treatment of patients with benign paroxysmal positional vertigo (BPPV). BACKGROUND: Alternative theories for the pathophysiology of BPPV have been redefined in the past few years. CRP is considered to be the standard technique for its management. However, long-term follow-up results have been minimally reported in the literature. PATIENTS/METHODS: Five hundred ninety-two patients, 290 (49%) men and 302 (51%) women, were enrolled in this prospective study; their ages ranged from 18 to 84 (mean 59) years. At the time of their first examination, patients reported the duration of symptoms varied from 1 day to 18 months. Inclusion criteria were patient history compatible with BPPV and positive provocative maneuver (either Dix-Hallpike or Roll test). A variant of Epley and Barbeque maneuver was used. The Epley maneuver was used for posterior and anterior canal involvement, and "Barbeque roll" was used for horizontal canal involvement. Short-term follow-up was obtained 48 hours and 7 days after initial treatment, whereas long-term follow-up was obtained at repeated 6 month intervals. RESULTS: The posterior semicircular canal was involved in 521 (88%) patients treated, whereas the horizontal and anterior semicircular canals were involved in 59 (10%) and 12 (2%) patients, respectively. Symptoms subsided immediately in 497 (84%) patients. In 77 (13%) patients, the Dix-Hallpike maneuver remained positive after 48 hours, and CRP was performed again. Patients' mean follow-up was 46 months; 544 (92%) of 592 patients treated reported no symptoms of vertigo. CONCLUSION: Our data, based on long-term follow-up, suggest that CRP remains an efficient and long-lasting noninvasive treatment for BPPV.     

Surgical management for benign paroxysmal positional vertigo of the superior semicircular canal

Benign paroxysmal positional vertigo of the superior semicircular canal is a rare form of BPPV. It accounts for 1% to 3% of cases. The characteristic nystagmus is positional, down‐beating, with a torsional component elicited by the Dix‐Hallpike maneuver. Symptoms of superior semicircular canal BPPV often resolve spontaneously; however, it can be refractory to repositioning maneuvers. Surgical management is described for posterior semicircular canal BPPV. To date, however, there is only one reported case of surgical management for superior semicircular canal BPPV. Here we show video documentation of positional, down‐beating nystagmus and describe a case of superior semicircular canal BPPV requiring canal occlusion with successful resolution of symptoms.
