Key Clinical Message: Repositioning maneuvers for benign paroxysmal positional vertigo (BPPV) designed to induce otoconial movement in one canal can trigger and sometimes unwittingly treat BPPV in other canals. Patients with BPPV are best managed by precisely diagnosing the canal variant and using correctly performed, standardized testing and treatment maneuvers. [ABSTRACT FROM AUTHOR]

Objectives: The Epley maneuver (EM) shows immediate effect, wherein disappearance of positional nystagmus occurs soon after the EM. Our previous study showed that setting interval times during the EM reduced the immediate effect. The purpose of this study is to identify the head position for which interval time reduces the immediate effect. Methods: Fifty-one patients with posterior canal type of benign paroxysmal positional vertigo (BPPV) were randomly assigned to the following three groups: 10 min interval time set at the first head position of the EM in group A, at the third head position in group B, and at the fourth head position in group C. The primary outcome measure (POＭ) was the ratio of maximum slow-phase eye velocity of positional nystagmus soon after the EM, compared with that measured before the EM. A large ratio value indicates a poor immediate effect of the EM. Results: The POＭ in group A (0.07) was smallest (B: 0.36, C: 0.49) (p < 0.001). Discussion: The interval times at the third and fourth head positions reduced the immediate effect of the EM. Our previous study showed that the effect of BPPV fatigue is continued by maintaining the first head position of the EM. BPPV fatigue constitutes fatigability of positional nystagmus with repeated performance of the Dix-Hallpike test. Our findings may be interpreted in accordance with the theory that the immediate effect of the EM is BPPV fatigue itself, because we observed that the effect of BPPV fatigue is strongest in group A.

Pharmacological therapies are used to control Benign paroxysmal positional vertigo (BPPV) symptoms for a brief period, discontinuing them usually results in recurrence. Canalolith repositioning maneuvers, including Epley, Semont, and Gans maneuvers, have been recommended for treating posterior canal BPPV with a high rate of success. A prospective, quasi-randomized study was carried out to compare the efficacy of Epley, Semont, and Gans maneuvers in the treatment of posterior canal BPPV and their durability. All patients over the age of 20 who met the BPPV diagnostic criteria, regardless of gender, were included in the study. Diagnosis of BPPV was done by Dix Hallpike maneuver. Typical posterior canal BPPV, the most frequent form of BPPV, is characterized by paroxysmal nystagmus evoked through the Dix-Hallpike test; the nystagmus is torsional clockwise for the left side, counter-clockwise for the right side, with a vertical up-beating component. The patients were uniformly quasi-randomized in a 1:1:1 ratio to be treated with Epley, Semont, and Gans maneuvers. After performing the maneuver, the patients were again subjected to the Dix-Hallpike test. Based on the result of the Dix-Hallpike test's positivity, the maneuvers were repeated up to three times. All the patients were called for a reassessment 30 days after the last intervention to assess the durability of the maneuver. In the study, 54.44% (49) of the 90 patients were female, whereas 45.56% (41) were male. Overall, 83.33% (75) of patients required only one attempt, 15.56% (14) required two attempts, and 1.11% (1) required three attempts to improve. In the Epley maneuvers group, 86.66% (26) required only one attempt, 10% (3) required two attempts, and 3.33% (1) required three attempts. Similarly, 83.33% (25) required only one attempt in the Gans maneuvers group, and 16.67% (5) required two attempts. In Semont maneuver groups, 80% (24) required only one attempt, and 20% (6) required two attempts. The recurrence of the symptoms was seen in a total of 11 patients: 27.27% (3 patients) of the Epley maneuvers group, 36.36% (4 patients) of the Gans maneuvers group, and 36.36% (4 patients) of the Semont maneuvers group. All three maneuvers show equal efficacy in reducing vertigo. The Epley maneuver may be more relevant in the treatment of BPPV compared to others, considering the slightly higher improvement rate and the requirement for fewer attempts for the treatment.

Background: The treatment of benign paroxysmal positional vertigo (BPPV) has not been well studied. Many clinicians are indifferent about canalith reposition maneuvers and frequently prefer medical treatments. Objectives: We aimed to detect efficacy of Epley maneuver in relieving symptoms of benign paroxysmal positional vertigo patients diagnosed in emergency department and if medical treatments are useful in patients whose symptoms were not relieved. Methods: The study was conducted as a prospective cohort study in the emergency department of a tertiary hospital. Patients who were over 18 years of age and presented to emergency department with complaints of vertigo symptoms and nausea and had a positive Dix–Hallpike test were included in the study. Patients' demographic data, possible etiological factors, affected ear, and benign paroxysmal positional vertigo diagnosis in the history were recorded on the study data form. The European Evaluation of Vertigo scale and the Visual Analogue Scale (VAS) score of nausea and vertigo symptoms were graded and recorded for each patient before and after treatment. Results: Ninety patients were included in the study in total. Epley maneuver was carried out to all patients. Vertigo symptoms VAS (VASd) score (p < 0.001), nausea and vomiting VAS (VASnv) score (p < 0.001), and European Evaluation of Vertigo scale score (p < 0.001) of all patients showed a statistically significant decrease after Epley maneuver. A combination of dimenhydrinate and metoclopramide helped to reduce VASd (p = 0.048), VASnv (p = 0.031), and European Evaluation of Vertigo scale scores (p = 0.001) at a statistically significant level more than dimenhydrinate treatment alone. Conclusions: Epley maneuver may be applied to every patient with benign paroxysmal positional vertigo. Dimenhydrinate and/or metoclopramide helps to control patients' symptoms whose symptoms remain despite Epley maneuver. [ABSTRACT FROM AUTHOR]

ObjectiveTo compare the repositioning effect of the modified Epley maneuver and the traditional Epley maneuver for posterior semicircular canal benign paroxysmal positional vertigo (PC-BPPV).MethodsSixty-five patients with unilateral PC-BPPV were randomly divided into two groups. The control group received the traditional Epley maneuver, while the experimental group received the modified Epley maneuver, which prolonged the time in the healthy side lying position and the final bowing position. The number of successful repositions after one, two, and three attempts and the total number of successful repositions were recorded and compared between the two groups. A BPPV virtual simulation model was used to analyze the mechanism of the modified Epley maneuver.ResultsThe first repositioning success rate of the experimental group was significantly higher than that of the control group (85% vs. 63%, p = 0.040). The experimental group achieved 100% repositioning success rate after two attempts, while the control group needed three attempts to reach 86% repositioning success rate. Four cases in the control group experienced canal switching during the repositioning process, while none in the experimental group did. The BPPV virtual simulation model showed that the modified Epley maneuver could facilitate the passage of otoliths through the posterior arm of the posterior semicircular canal, especially through the location of obstruction.ConclusionThe modified Epley maneuver is more effective than the traditional Epley maneuver in improving the single repositioning success rate and reducing the canal switching rate for PC-BPPV. This study provides a new option for the treatment of BPPV.

Background: Benign paroxysmal positional vertigo (BPPV) is considered the most common cause of vertigo. The necessity for early and effective management resulted in the improvement of the patient's life quality. The objective was to compare the efficacy between Epley's maneuver and betahistine dihydrochloride in BPPV treatment. Patients and Methods: A prospective follow-up comparative study on 60 patients with BPPV, who diagnosed with a positive Dix–Hallpike test, were divided equally and randomly into two groups; Group "A" treated with Epley's maneuver and Group "B" treated with betahistine dihydrochloride. The efficacy of each modality was assessed, regarding the sense of vertigo and its associated symptoms, data of vertigo scales as the Visual Analog Scale (VAS), and Dizziness Handicap Inventory (DHI). Results: There were 23 males (38.33%), and 37 females (61.66%), with mean age (54 ± 7.521) years. The total vertigo improvement was (78.33%); being (93.33%) in group "A" and (63.33%) in group "B", nausea and vomiting symptoms improvement was (76.66%) in group "A", and (70%) in group "B". The baseline VAS score in Group "A" (7.69 ± 1.235 SD) and in Group "B" (6.35 ± 3.267 SD) after treatment improved to 0.56 ± 0.731 SD and 1.86 ± 1.375 SD, respectively, as well as the baseline DHI value in Group "A" (51.86 ± 23.583 SD) and in Group "B" (49.37 ± 18.152 SD) then improved to 2.31 ± 3.986 and 7.98 ± 9.512 SD, respectively. Conclusions: The Epley maneuver was more effective and "statistically significant" in relieving vertigo, and both the VAS and DHI scales compared to betahistine, while regarding associated nausea and vomiting symptoms, it shows no statically significant difference.

BACKGROUND: The aim of this study was to show the variability in head angulation during the canalolith repositioning maneuvers to treat benign paroxysmal positional vertigo and to describe a head-mounted benign paroxysmal positional vertigo guidance system to measure the head orientation. METHODS: A guidance system for benign paroxysmal positional vertigo was developed by NeuroEquilibrium Diagnostic Systems to measure head orientation and provide visual feedback and instructions to examiners during various maneuvers for benign paroxysmal positional vertigo. Twenty-five experienced examiners and 25 healthy volunteers (aged 21-35 years) were recruited. Each examiner applied the Epley maneuver twice in 1 volunteer: without and with the use visual feedback from a guidance system. Head orientation in both procedures was measured and compared. RESULTS: The trained examiners demonstrated a large variability in head orientation during the Epley maneuver, which was reduced by using the benign paroxysmal positional vertigo guidance system. There was a variability of 39-65° in head orientation measured without the guidance system. The use of the guidance system reduced the variation range to a sixfold decrease in variability. CONCLUSION: There is a large variability in head orientation when performing repositioning maneuvers, which could compromise the efficacy of benign paroxysmal positional vertigo treatment. Treatment for benign paroxysmal positional vertigo can be optimized by reducing this variability with a benign paroxysmal positional vertigo guidance system. It might also be a useful tool for teaching. [ABSTRACT FROM AUTHOR]

Based on the current state of the BPPV field, there are no guidelines that specify an angular head movement's velocity (AHMV) during diagnostic maneuvers of BPPV. The aim of this study was to evaluate the impact of AHMV during diagnostic maneuvers on proper BPPV diagnosis and therapy. The analysis covered the results obtained in 91 patients with a positive result of the Dix-Hallpike (D-H) maneuver or the roll test. The patients were divided into four groups based on values of AHMV (high 100–200°/s and low 40–70°/s) and the BPPV type (posterior: PC-BPPV or horizontal: HC-BPPV). The parameters of the obtained nystagmuses were analyzed and compared to AHMV. There was a significant negative correlation between AHMV and latency of nystagmus in all study groups. Furthermore, there was a significant positive correlation between AHMV and both maximum slow phase velocity and average frequency of nystagmus in the PC-BPPV groups, whereas it was not observed in the HC-BPPV patients. Complete relief of symptoms was reported after 2 weeks and was better in patients diagnosed with maneuvers performed with high AHMV. High AHMV during the D-H maneuver allows the nystagmus to be more visible, increasing the sensitivity of diagnostic tests and is crucial for a proper diagnosis and therapy. [ABSTRACT FROM AUTHOR]

Objective: To investigate if alternated Epley (EP) and Semont (ST) maneuvers could be more effective than repetition of the same in benign paroxysmal positional vertigo of posterior semicircular canal (pBPPV). Design: We retrospectively reviewed the outcome of pBPPV patients treated with a second maneuver for the persistence of positional nystagmus. Study Sample: Forty-seven patients underwent 2 STs, 64 with 2 EPs, and 71 EPs followed by ST. Videonystagmography and Dizziness Handicap Inventory (DHI) questionnaire were performed. Results: Absence of positional nystagmus was achieved after 2 maneuvers in 136 patients with pBPPV: 65.9% in the ST group, 70.3% in the EP group, and 84.5% in the EP-ST group. Alternated EP and ST were significantly more effective than repeated ST (P =.03), while we found no significant difference when compared with repeated EP (P =.07). At 1-month follow-up, 12 patients showed persistent positional nystagmus without difference between groups. After 1 month, the 46 patients with negative outcome had significantly higher DHI values (P =.01) than other 136 patients with pBPPV. Conclusions: Alternated EP and ST seemed more effective than repeating the same maneuver in treating pBPPV, and this should be confirmed in prospective clinical studies. Resolution of nystagmus after maneuvers was fundamental to reduce handicap deriving from dizziness as reported in DHI. [ABSTRACT FROM AUTHOR]

Introduction: Benign paroxysmal positional vertigo is a common vestibular disorder that accounts for one fifth of hospital admissions due to vertigo, although it is commonly undiagnosed. Objective: To evaluate the effects of betahistine add-on therapy in the treatment of subjects with posterior benign paroxysmal positional vertigo. Methods: This randomized controlled study was conducted in a population of 100 subjects with posterior benign paroxysmal positional vertigo. Subjects were divided into the Epley maneuver + betahistine group (group A) and Epley maneuver only (group B) group. Subjects were evaluated before and 1-week after the maneuver using a visual analog scale and dizziness handicap inventory Results: One hundred subjects completed the study protocol. The Epley maneuver had an overall success rate of 95% (96% in group A; 94% in group B, p = 0.024). Groups A and B had similar baseline visual analog scale scores (6.98 ± 2.133 and 6.27 ± 2.148, respectively, p = 0.100). After treatment, the visual analog scale score was significantly lower in both groups, and was significantly lower in group A than group B (0.74 ± 0.853 vs. 1.92 ± 1.288, respectively, p = 0.000). The change in visual analog scale score after treatment compared to baseline was also significantly greater in group A than group B (6.24 ± 2.01 vs. 4.34 ± 2.32, respectively, p = 0.000). The baseline dizziness handicap inventory values were also similar in groups A and B (55.60 ± 22.732 vs. 45.59 ± 17.049, respectively, p = 0.028). After treatment, they were significantly lower in both groups. The change in score after treatment compared to baseline was also significantly greater in group A than group B (52.44 ± 21.42 vs. 35.71 ± 13.51, respectively, p = 0.000). Conclusion: The Epley maneuver is effective for treatment of benign paroxysmal positional vertigo. Betahistine add-on treatment in posterior benign paroxysmal positional vertigo resulted in improvements in both visual analog scale score and dizziness handicap inventory.

To evaluate the effects of the modified Epley maneuver during Posterior Canal Benign Paroxysmal Positional Vertigo (BPPV) on patients' anxiety and comfort levels. The study, organized as a prospective, worked with 72 patients who were diagnosed with Posterior Canal BPPV through Dix-Hallpike maneuver. The data for the study was collected through Descriptive Characteristics Form, General Comfort Questionnaire Short Form, and Beck Anxiety Inventory. It was found that that 63.9% of the patients experienced average-level anxiety before the implementation of the Epley maneuver and received a total of 3.07 ±.37 (1–6) from the General Comfort Questionnaire. Before applying the modified Epley maneuver and I and IV When the score changes after the week were examined, it was determined that there was a statistically significant difference in all scale scores, as comfort levels increased, anxiety levels decreased. Anxiety was identified as the most important predictor of patients' comfort level before and after the implementation of the modified Epley maneuver. In light of these findings, it can be said that modified Epley maneuver can safely be used to increase the comfort of patients with Posterior Canal BPPV. Considering that patients with BPPV can consult to emergency rooms, family clinics along with polyclinics, it is recommended to organize regular trainings on BPPV and the implementation of the Epley maneuver. It is believed that evaluation of BPPV patients for their anxiety and offer support when needed is important for the prognosis and patients' comfort. [ABSTRACT FROM AUTHOR]

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.

The aim was to compare the effectiveness of Brandt-Daroff, Semont and Epley maneuver in BPPV resolution. A Single Blind RCT in a Secondary Care Center was performed. Inclusion criteria were: patients with unilateral rotatory nystagmus on Dix-Hallpike Maneuver (DHM). Exclusion criteria: other causes of peripheral or central vertigo. Patients were randomized into 4 groups: Brandt-Daroff, "sham", Semont and Epley. Patients underwent allocation, 1st visit (at 1 week with reprise of original maneuver if persistent nystagmus) and 2nd visit (2 to 4 weeks) with repetitions of both DHM and DHI. Main Outcome Measures: Absence of nystagmus on DHM at 1st and 2nd visit evaluations and DHI score. Resolution was defined as the abscence of nystagmus. We included 34 patients (25 females, 9 males). Patients were randomized to Brandt-Daroff (n = 9), "sham" (n = 7), Semont (n = 9) and Epley (n = 9) group. Overall mean age was 59.85 years (SD ± 13.10). A total of 47.06% patients (n = 16) had negative DHM at 1st visit. Resolution for Brandt-Daroff was 22.22%, "sham" 28.57%, Semont 44.44% and Epley 88.88% (p = 0.024); at 2nd visit follow up, Epley achieved 100% resolution (other maneuvers: 42.86%, 16.67%, 44.44%, respectively. P = 0.006). The DHI improvement at 2nd visit for Brandt-Daroff was 21.17 points, "sham" 8.05, Semont 14.67 and Epley 61.78 (p = 0.001). Epley maneuver was superior to Brandt Daroff, "sham" and Semont maneuvers on nystagmus resolution and DHI improvement in patients with BPPV. [ABSTRACT FROM AUTHOR]

Background and objectives: BPPV (benign paroxysmal positional vertigo) is a syndrome marked by brief bouts of vertigo accompanied by rapid changes in head position. Recent ongoing therapeutic approaches used are vestibular rehabilitation exercises and physical maneuvers like the Epley maneuver, Semont maneuver. Gans repositioning maneuver (GRM) is a new hybrid maneuver, consisting of safe and comfortable series of postures that can be conveniently applied on patients with any spinal pathology or even in elderly. Methods: Randomized controlled/clinical trials of the Gans maneuver were identified. The proportion of patients who improved as a result of each intervention was assessed, as well as the conversion of a 'positive' Dix–Hallpike test to a 'negative' Dix–Hallpike test. Results: Improvement was seen in almost all patients with the Gans maneuver and the Epley Maneuver in three trials with the pooled estimate for random effect model is 1.12 [0.87; 1.43: 100%]. There were no significant side effects from the treatment. Discussion: This study shows that the Gans maneuver is a safe and effective treatment for patients suffering from posterior canal BPPV. Trial registration: The review is registered in Prospero with no. CRD42021234100. [ABSTRACT FROM AUTHOR]

Subjective Benign Paroxysmal Positional Vertigo (S-BPPV) is an atypical form of BPPV, its treatment is not well characterized and is not well known among otolaryngologists. The main aim of this study was to estimate the short-term efficacy of Epley maneuver as treatment for S-BPPV. This was a prospective study in a secondary care center. We included patients with unilateral S-BPPV demonstrated by negative nystagmus on Dix-Hallpike Maneuver (DHM) but with unilateral vestibular symptoms (dizziness or vertigo). Epley maneuver to the affected side was performed. Patients underwent Dizziness Handicap Inventory (DHI) and at 1-week follow-up, DHI and DHM were repeated. Outcome measures were resolution of symptoms during DHM and improvement of DHI scores. Patients were divided into resolved and unresolved groups according to the absence or presence of symptoms during the 1 week DHM. Wilcoxon-Mann–Whitney and Kruskal–Wallis tests were used, quantitative values were reported as mean and standard deviation. The results included thirteen participants, 12 females and 1 male, mean age 53.31 years (SD ± 15.71). Right ear was involved in 46.15% and left in 53.84%. A total of 46.15% patients (n = 6) had resolution of symptoms. DHI initial score for the resolved group was 34.66 ± 22 and for the unresolved group was 39.71 ± 19.61 (p = 0.568). At 1-week evaluation scores were 19.66 ± 25.05 for the resolved group and 30.28 ± 21.42 for the unresolved group (p = 0.252). DHI improvement was 15.00 ± 23.21 and 9.42 ± 10.17 for each group, respectively (p = 0.943). We concluded the Epley maneuver is an effective short-term treatment for S-BPPV. Half of the patients would need further diagnostic tests. [ABSTRACT FROM AUTHOR]

Introduction: Posterior canal benign paroxysmal positional vertigo (PC-BPPV) is considered the most common cause of peripheral vertigo in the emergency department (ED). Although the canalith repositioning maneuver (CRM) is the standard of care, the most effective method to deliver it in the ED has been poorly studied. Objective: To compare two protocols of the Epley maneuver for the treatment of PC-BPPV. Patients and methods: We prospectively recruited 101 patients with unilateral PC-BPPV on physical examination, randomizing them to either a single Epley maneuver (EM) (n = 46) or multiple maneuvers (n = 55) on the same visit. Measured outcomes included presence/absence of positional nystagmus, resolution of vertigo, and score on the dizziness handicap inventory (DHI) at follow-up evaluations. The DHI was stratified into mild (≤30) and moderate-severe (>30). Results: Normalization of the Dix-Hallpike maneuver at day 5 was observed in 38% of the single EM group and 44.4% in the multiple EM group (p = 0.62). The DHI showed reduction from 42.2 (SD 18.4) to 31.9 (SD 23.7) in the single EM group and from 43.7 (SD 22.9) to 33.5 (SD 21.5) in the multiple EM group (p = 0.06). A higher number of patients improved from moderate-severe to mild DHI (p = 0.03) in the single EM group compared to the multi-EM group (p = 0.23). Conclusion: There was no statistically significant difference between performing a single EM versus multiple EMs for treatment of PC-BPPV in the emergency department. The single EM approach is associated with shorter physical contact between patients and examiner, which is logically safer in a pandemic context.

The objective of this research was to investigate the mechanism of canal switching in benign paroxysmal positional vertigo through a virtual simulation model. Using Unity 3D software and a built-in NVIDIA Physx physics engine, the virtual simulation software is developed using a browser-server architecture, and differentmodels are imported. Based on the benign paroxysmal positional vertigo virtual simulation model, we constructed five different virtual reality scenes of diagnosis and treatment, set otoliths in different positions of the semicircular canals, and analyzed the effects of diagnostic and therapeutic procedures on otolith location. Through the analysis of otolith movement in five virtual scenes, we found that canal switching may be caused by otoliths in the utricle entering the semicircular canal in the supine position. Then, we used different methods to reposition the otolith, improved the repositioning maneuver, and explored in depth the mechanism of the canal switching. The results showed that the main reason for the canal switch is that in the supine position, the otolith in the utricle enters the semicircular canal. The repositioningmaneuvers, including the Epleymaneuver and Barbecuemaneuver, will not directly lead to the canal switch in the ipsilateral inner ear. The supine roll maneuver leads to the otolith in the utricle entering the posterior or lateral semicircular canal, which is the most likely mechanism for canal switching. [ABSTRACT FROM AUTHOR]

Objectives Canalolithiasis of the posterior semicircular canal (PC) is the most common reason for benign paroxysmal positional vertigo (BPPV). If a patient is diagnosed with PC-BPPV through the Dix-Hallpike test, the modified Epley maneuver (mEpley) is used as the gold standard treatment. To reduce the discomfort of the standard mEpley, we proposed placing a pillow under the shoulders during this therapeutic maneuver. The purpose of this study was to determine whether the therapeutic efficacy of the mEpley with a pillow under the shoulders (mEpley-PS) was comparable to that of the standard mEpley. Methods A randomized controlled study at three academic referral hospitals was conducted in compliance with the CONSORT statement. Patients who were diagnosed with PC-BPPV through the Dix-Hallpike test were randomly assigned to groups A or B. Patients in groups A and B were treated with the standard mEpley and mEpley-PS, respectively. The resolution of vertigo and nystagmus on the Dix-Hallpike test at a 1-week follow-up after treatment was the main outcome measurement to assess the efficacy of treatment. Results Forty-one patients diagnosed with PC-BPPV were enrolled in this study. Twenty-one patients were assigned to group A and 20 were assigned to group B. The success rate at 1 week after treatment was 85.7% in group A and 80.0% in group B. There was no statistically significant difference between the two groups (P=0.697). Conclusion The therapeutic efficacy of the mEpley-PS was comparable to that of the standard mEpley. The use of the pillow modification may be an excellent alternative if a patient cannot tolerate the head-hanging position, and it is helpful for patients who have anxiety about the head-hanging position. The mEpley-PS can be performed on a bed with or without a headboard. It is both a patient-friendly and a clinician-friendly maneuver.

BACKGROUND: Low success and high recurrence of benign paroxysmal positional vertigo (BPPV) after home-based self-treated Epley and Barbeque (BBQ) roll maneuvers is an important issue. OBJECTIVE: To quantify the cause of low success rate of self-treated Epley and BBQ roll maneuvers and provide a clinically acceptable criterion to guide self-treatment head rotations. METHODS: Twenty-five participants without active BPPV wore a custom head-mount rotation monitoring device for objective measurements. Self-treatment and specialist-assisted maneuvers were compared for head rotation accuracy. Absolute differences between the head rotation evaluation criteria (American Academy of Otolaryngology guidelines) and measured rotation angles were considered as errors. Self-treatment and specialist-treated errors in maneuvers were compared. Between-trial variations and age effects were evaluated. RESULTS: A significantly large error and between-trial variation occurred in step 4 of the self-treated Epley maneuver, with a considerable error in the second trial. The cumulative error of all steps of self-treated BBQ roll maneuver was significantly large. Age effect occurred only in the self-treated BBQ roll maneuver. Errors in specialist-treated maneuvers ranged from 10 to 20 degrees. CONCLUSIONS: Real-time feedback of head movements during simultaneous head-body rotations could increase success rates of self-treatments. Specialist-treated maneuvers can be used as permissible rotation margin criteria. [ABSTRACT FROM AUTHOR]

OBJECTIVE: Benign Paroxysmal Positional Vertigo (BPPV) as the most common vestibular disorder can affect the quality of life. This study aimed to compare the effectiveness of the half somersault maneuver (HSM) as a treatment to that of the Epley maneuver (EM) as a clinical-based treatment in subjects with PC-BPPV. METHODS: In this randomized study, 43 participants with unilateral posterior canal BPPV were recruited. The experimental group received the HSM, whereas the control group received the EM. All participants were asked to fill in the Vestibular Rehabilitation Benefit Questionnaire (VRBQ), Dizziness Handicap Inventory (DHI), and Vertigo Symptom Scale (VSS) questionnaires at pretreatment and at 48 hours, 1 week, and 1 month posttreatment. The severity of residual dizziness was determined by the visual analog scale (VAS) weekly for up to 4 weeks after treatment. The success rate and the recurrence rate were assessed after the 3-month follow-up. RESULTS: The differences between the results of pretreatment and post-treatment questionnaires for both groups were significant. However, the differences were not significant between the 2 groups for the DHI scores, the total, dizziness, motion-provoked dizziness, and symptom subscale scores of the VRBQ, and the anxiety subscale scores of the VSS. There were significant differences between the 2 groups for VAS, the total VSS and vertigo subscale scores, and the VRBQ anxiety subscale scores. CONCLUSION: Even though both maneuvers are significantly effective in the treatment of PC-BPPV, subjects in the HSM group reported more improvement in terms of psychometric symptoms and residual dizziness compared to the EM group.

Objective:Benign paroxysmal positional vertigo (BPPV) is the most common peripheral vestibular system disease causing dizziness. It occurs more in the 5th decade of life and affects the posterior canal in 90% of the patients. The most effective treatment method is canalith repositioning (CRP) maneuver. The aim of this study is to evaluate the effects of betahistine and dimenhydrinate therapies in addition to CRP maneuver on BPPV patients.Methods:The study included 64 patients who had complaints of dizziness and were diagnosed with BPPV by their history and provocation maneuvers. The patients were divided into two groups. In Group 1, only repositioning maneuver was performed. Group 2 was divided into two subgroups. In Group 2a, repositioning maneuver was performed and betahistine 24 mg twice daily was given for 10 days. In Group 2b, repositioning maneuver was performed and dimenhydrinate 50 mg once daily was given for five days. On the 10th day, all patients were reexamined, and provocation maneuver was performed. Dizziness handicap inventory (DHI) was completed and outcomes were reviewed for therapeutic efficacy.Results:Mean DHI scores in all patient groups statistically significantly decreased from a pre-treatment level of 52.16 (range, 20-100) to a post-treatment level of 17.84 (range, 0-78) (p

Objectives: The purpose of this study is to investigate a modified Epley maneuver for self-treatment of posterior canal benign paroxysmal positional vertigo (PC-BPPV).Methods: The study recruited 155 patients with PC-BPPV. All patients were randomized into the Epley maneuver group (n = 77) and modified Epley maneuver group (n = 78). We analyzed the resolution rate (1 day and 1 week), residual symptoms after the maneuver, and adverse effects.Results: It was found that the modified Epley maneuver group had a higher resolution rate than that of the Epley maneuver group in the treatment of PC-BPPV after 1 day of the initial maneuver (p < 0.05). However, there was no difference in resolution rate between the Epley maneuver group and the modified Epley maneuver group in resolution rate after 1 week of the initial maneuver (p > 0.05). The modified Epley maneuver group had fewer residual symptoms than that of the Epley maneuver group 1 week after treatment of PC-BPPV (p < 0.05). Significant improvements were also observed in average DHI scores in patients who underwent the modified Epley maneuver compared to the Epley maneuver (p < 0.05). There was no significant difference in adverse effects between the two groups (p > 0.05).Conclusions: The modified Epley maneuver has a satisfactory therapeutic efficacy with less residual symptoms and could be recommended as a self-treatment for patients with PC-BPPV.

Objective: To investigate the therapeutic efficacies of the Epley maneuver and Brandt-Daroff (BD) exercise in patients with benign paroxysmal positional vertigo involving the posterior semicircular canal cupulolithiasis (PC-BPPV-cu).Methods: We conducted a randomized clinical trial to evaluate the therapeutic effect of the Epley maneuver and BD exercise in patients with PC-BPPV-cu. Patients were randomly assigned to undergo the Epley maneuver (n = 29) or BD exercise (n = 33). The primary outcome was an immediate resolution of positional nystagmus within 1 h after a single treatment of each maneuver on the visit day. Secondary outcomes included the resolution of positional nystagmus at 1 week, the change of maximal slow phase velocity (mSPV) of positional nystagmus, and dizziness handicap inventory (DHI) immediately and at 1 week.Results: Immediate resolution occurred in none of 29 patients in the Epley maneuver group and only 1 of 33 patients in the BD exercise group. The Epley maneuver and BD exercise had an equivalent effect at 1 week in treating PC-BPPV-cu in terms of resolving positional nystagmus (48 vs. 36%, p = 0.436) and the decrease of mSPV and DHI.Conclusion: Neither the Epley maneuver nor BD exercise has an immediate therapeutic effect in treating PC-BPPV-cu. Clear classification of PC-BPPV should be required at the time of different pathology and different treatment response.

Objective: In this study, we aimed to investigate the effectiveness of the Epley maneuver performed without any additional medical treatment on symptoms and quality of life in patients diagnosed with canalithiasis type posterior canal BPPV with the Dix-Hallpike (DH) test in two District Hospitals of Antalya-Turkey. Methods: A total of 55 patients who were admitted to the ENT Departments Kumluca and Serik State Hospitals, Antalya between November 2019 and June 2020 with complaining of positional vertigo who were diagnosed as posterior canal BPPV with the Dix Hallpike (DH) test was included in this study. Results: Fifty-five cases with dizziness and vertigo complaints enrolled in our study. Thirty-four of the patients were male (%43.6), and 21 cases were female (%56.4). The ages of the patients were between 32 and 81with an average of 52.4±13.3 years. Statistically significant improvement was obtained at Vertigo Symptom Scale, Vertigo Dizziness Imbalance Symptom Scale, and Vertigo, Dizziness Imbalance health-related quality of life scale after the application of Epley maneuver. Conclusion: In our study, Epley maneuver efficacy without any additional medical treatment was found to be very high in BPPV patients. As a result of this study, we wanted to emphasize that medical treatment to every patient presenting with dizziness and vertigo complaints is not a correct approach. [ABSTRACT FROM AUTHOR]

Objectives/hypothesis: The present study aimed to evaluate the optimal reassessment time for treatment response in posterior canal benign paroxysmal positional vertigo (PC-BPPV) following the initial Epley maneuver.Study Design: Prospective, single-blinded, randomized study.Methods: One hundred eight patients with PC-BPPV agreed to participate. These patients received a single modified Epley maneuver (recommended by the 2008 American Academy of Otolaryngology-Head and Neck Surgery guidelines) daily until positional nystagmus disappeared during the Dix-Hallpike maneuver 24 hours after the treatment. Repeated Dix-Hallpike testing to reassess the treatment response was performed at 1 hour (post-1 hour), every 24 hours (post-24 hours) until the positional nystagmus resolved, 1 week (post-1 week), and 1 month (post-1 month) following the therapeutic maneuver. The difference in the resolution rates at post-1 hour and post-24 hours reassessment was analyzed, and the recurrence rates at post-1 week and post-1 month were evaluated.Results: The resolution rate was 67.6% at post-1 hour, which increased to 79.6% at post-24 hours reassessment. There was a statistically significant difference in the results of the Dix-Hallpike test between post-1 hour and post-24 hours follow-up. After complete resolution, nine out of 108 patients (8.3%) demonstrated recurrence within 1 month.Conclusions: Reassessment after 24 hours following the initial Epley maneuver is more advantageous than a 1-hour follow-up in patients with PC-BPPV. This information may be helpful for clinicians in deciding the appropriate follow-up period after treatment for PC-BPPV.Level Of Evidence: 1b Laryngoscope, 130:496-499, 2020. [ABSTRACT FROM AUTHOR]

Objective: The Epley maneuver (EM) has an immediate effect: rapid reduction of positional nystagmus. Benign paroxysmal positional vertigo (BPPV) causes BPPV fatigue, which constitutes fatigability of positional nystagmus and vertigo with repeated performance of the Dix-Hallpike test; notably, BPPV fatigability becomes ineffective over time. We hypothesized that the immediate effect of the EM is caused by BPPV fatigue. Therefore, we suspected that performance of the EM with intervals between head positions would worsen the immediate reduction of positional nystagmus in patients with BPPV, because BPPV fatigability would become ineffective during performance of this therapy.Methods: Forty patients with newly diagnosed BPPV were randomly assigned to the following two groups; one group performed the EM without intervals between positions (group A), and the other group performed the EM with 3 min intervals between positions (group B). The primary outcome measure was the ratio of maximum slow-phase eye velocity (MSPEV) of positional nystagmus soon after the EM, compared with that measured before the EM. Secondary outcome included whether a 30 min interval after the EM enabled recovery of MSPEV of positional nystagmus to the original value. This study followed the CONSORT 2010 reporting standards.Results: In both groups A and B, the immediate effect of the EM could be observed, because MSPEV during the second Dix-Hallpike test was significantly smaller than MSPEV during the first Dix-Hallpike test (p < 0.0001 in group A, p < 0.0001 in group B). The primary outcome measure was larger in group B than in group A (p = 0.0029). The immediate effect faded 30 min later (secondary outcome).Conclusions: This study showed that the EM had an immediate effect both with and without interval time in each head position of the EM. Because setting interval time in each head position of the EM reduced the immediate effect of the EM, interval time during the EM adds less benefit. This finding can reduce the effort exerted by doctors, as well as the discomfort experienced by patients with pc-BPPV, during EM. However, this immediate effect may be caused by BPPV fatigue, and may fade rapidly.Classification of Evidence: 1b

OBJECTIVES: This study aimed to evaluate the efficacy of the repositioning maneuver on quality of life in elderly patients with dizziness and/or vertigo. MATERIALS and METHODS: This controlled, prospective randomized clinical trial was conducted in elderly patients aged 65 years and above with a positive history of benign paroxysmal positional vertigo (BPPV), presence of vertigo, and no observable nystagmus during the Dix-Hallpike test, so-called Subjective BPPV (S-BPPV). Individuals were evaluated by visual analog scale (VAS) and dizziness handicap inventory (DHI). Groups were defined as treatment (treated with Epley maneuver bilaterally) or no treatment control (no treatment modality or canalith repositioning maneuver). Ten days after the first assessment, all patients were reassessed using VAS and DHI. RESULTS: A total of 50 patients were randomized into two groups: 25 to the treatment group, and 25 to the control group. No significant differences were observed for baseline VAS and total DHI scores between the groups (p=0.636, p=0.846, respectively). On the other hand, after the reassessment, VAS and total DHI scores were both significantly reduced in the treatment group (p<0.001, p<0.001, respectively), but no reduction in either score was found in the control group (p=0.216, p=0.731, respectively). CONCLUSION: This study showed that elderly patients with S-BPPV benefit from the Epley maneuver, in particular global and disease-specific quality of life. [ABSTRACT FROM AUTHOR]

Dizziness handicap inventory (DHI) was completed and outcomes were reviewed for therapeutic efficacy. Results: Mean DHI scores in all patient groups statistically significantly decreased from a pre-treatment level of 52.16 (range, 20-100) to a post-treatment level of 17.84 (range, 0-78) (p<0.001). No statistically significant differences were found in terms of DHI scores between Group 1 (repositioning maneuver only) and Group 2 (repositioning maneuver plus betahistine or dimenhydrinate). Conclusion: The most effective treatment method of BPPV is repositioning maneuver. Addition of betahistine or dimenhydrinate pharmacotherapy to repositioning maneuver did not show superiority to treatment with repositioning maneuvers alone. [ABSTRACT FROM AUTHOR]

Dizziness is a common patient complaint with multiple etiologies. Many causes are benign, but NPs should consider red flags for serious differential diagnoses. A systematic patient history and physical exam are crucial to accurately diagnosing conditions related to dizziness. This article reviews common etiologies of dizziness and vertigo, assessment techniques, and treatment options. [ABSTRACT FROM AUTHOR]

Introduction: The most common causes of an acute attack of vertigo are: benign paroxysmal positional vertigo (BPPV), vestibular neuronitis, migraine, Meniere’s disease, orthostatic hypotension. In the pathogenesis of BPPV, one of the most common causes of an acute attack of vertigo is the pathology of the posterior semicircular canal (80%), BPPV of the horizontal semicircular canal are much less common. Diagnosis and treatment of this pathology is dependent on which of the semicircular canals are affected. Purpose: to show the features of diagnosis and evaluate the effectiveness of conservative methods of treatment of BPPV of the posterior and horizontal semicircular canals using repositional maneuvers. Materials and methods: An analysis was made of 13 patients with BPPV who contacted the Consultative and Diagnostic Department of JSC National Centre for Neurosurgery within 6 months in 2019. The analysis showed that the number of female patients prevails over the males: 83%. The average age is 51.4 years. The second most common symptom in patients with BPPV after dizziness is a feeling of nausea (75%). In 84.6% of patients, an acute episode of dizziness began in the morning. Only 2 out of 13 patients went to the doctor during the first 10-15 days, and 2 patients regularly and conscientiously visited the doctor. There was an improvement in 5 cases, and complete recovery and relief of dizziness occurred in 2 patients. A rare case of BPPV associated with pathology of the horizontal channel is presented to the attention of readers. Results: The use of diagnosis and treatment of BPPV of the horizontal semicircular canal proves the importance of correct and timely diagnosis of this disease and the high efficiency of repositional maneuvers. Conclusion: it is especially important in case of BPPV to determine the side of the lesion and localization: the posterior semicircular canal or the horizontal semicircular canal, since treatment tactics and the choice of repositional maneuvers depend on this. The treatment of DPPV with the use of repositioning maneuvers is highly effective and easy to carry out. [ABSTRACT FROM AUTHOR]

Background Benign Paroxysmal Positional Vertigo (BPPV) and other vestibular disorders are very common and often missed in older populations and are a significant risk factor and cause of falls. Vestibular rehabilitation is increasingly recognised as an effective intervention for the management of vestibular dysfunction in all age groups. This review aimed to explore the prevalence of vestibular disorders in the cohort attending an integrated day hospital falls assessment service and the feasibility of delivering vestibular rehabilitation interventions as part of this service. Methods We retrospectively reviewed the charts of all the patients who attended a new ambulatory day hospital between Nov 2018 and April 2019. Inclusion criteria included a recent history of falls and aged over 75. All patients had received a comprehensive geriatric assessment which included screening for vestibular symptoms and on-site assessment (if indicated) by a physiotherapist with expertise in vestibular rehabilitation. Results 40 patients (33 women, 7 men) with a mean age of 82 were seen in this period. All had suffered recent falls with 10 having suffered a fracture. 5 patients (12%) tested positive for Benign Paroxysmal Positional Vertigo and 2 others (5%) had evidence of both peripheral and central vestibular impairment. Vestibular rehabilitation interventions, including particle repositioning manoeuvres were delivered within the day hospital setting with review appointments offered to all patients. Conclusion This review highlights the high prevalence of vestibular disorders, especially BPPV (12%) in older fallers. It supports the feasibility of delivering vestibular assessments and rehabilitation as a component of the physiotherapy input within a day hospital falls service. [ABSTRACT FROM AUTHOR]

Objectives: To compare the outcome of the Epley maneuver (EM) in benign paroxysmal positional vertigo of the posterior canal (CSP‐BPPV) depending on the definition used for recovery. Design: Multicenter observational prospective study. Setting: Otoneurology Units of 5 tertiary reference hospitals. Participants: All patients presenting with unilateral CSP‐BPPV assisted for 1‐year period. Exclusion criteria: Spontaneous nystagmus, positive McClure‐Pagnini maneuver, positive bilateral Dix‐Hallpike maneuver (DHM), positive DHM for vertigo but negative for nystagmus and atypical nystagmus. Main outcome measures: Response to EM was measured after 7 days in 3 different outcomes: disappearance of nystagmus during the DHM in the follow‐up visit, disappearance of vertigo during the DHM and general status (GS) during daily life activities. Results: 264 patients were recruited (68 male/166 female, mean age 62 years). After the EM, nystagmus disappeared in 67% of them, vertigo in 54% and 36% were asymptomatic in their daily life. These outcomes were strongly correlated, but they were not concordant in a clinically significant group of cases; only the 26% of patients met all of them. The healing process follows the next sequence: negativization of positional nystagmus, then disappearance of positional vertigo and, finally, the improvement of GS during daily life activities. Conclusion: Nowadays, healing criteria for the resolution of an PSC‐BPPV episode have not been specifically defined yet. Provided that other otoneurological disorders have been ruled out, the next resolution criterion is proposed: absence of nystagmus and specifically during control DHM and disappearance of symptoms during daily life activities.

Purpose: Benign paroxysmal positional vertigo (BPPV) is a frequently underdiagnosed cause of vertigo, potentially due to the underuse of diagnostic and therapeutic canalith repositioning procedures (CRPs). We aimed to investigate self-reported use of the diagnostic and therapeutic approach to BPPV patients by Lithuanian neurologists, ear, nose, and throat (ENT) physicians, and general practitioners (GPs), and to explore potential reasons for the underuse of the maneuvers.Methods: Neurologists, ENT physicians, and GPs were invited to complete a written questionnaire focused on diagnostic and therapeutic practices related to BPPV. Between-group differences and associations between responses were analyzed statistically.Results: In total, 97 neurologists, 85 ENT physicians and 142 GPs (21.1%, 26.8%, and 5.7%, respectively, of all corresponding licensed Lithuanian physicians) completed the questionnaire. 24% of neurologists, 33% ENT physicians and 50% GPs do not perform diagnostic maneuvers for patients with suspected BPPV, and 28%, 61%, and 84%, respectively, do not perform CRPs. Years of clinical experience was a negative predictor of CRP performance [OR 0.97 (95% CI 0.95-0.99), p = 0.001]. Frequent reasons for not performing CRPs were time taken for the procedure, fear of provoking symptoms, and lack of knowledge. All physicians frequently ordered additional imaging or consultations for suspected BPPV and reported prescribing a range of medications.Conclusions: A significant proportion of Lithuanian neurologists, ENT physicians, and GPs do not employ diagnostic maneuvers and CRPs for BPPV patients, contrary to established guidelines. Lack of expertise and time available is a common culprit that leads to unnecessary drug prescribing and investigation. [ABSTRACT FROM AUTHOR]

Benign Paroxysmal Positional Vertigo (BPPV) is the most common cause in patients with vertigo (Pereira et al. in Braz J Otorhinolaryngol (Impr) 76(6):704-708, 2010; Dix and Hallpike in Ann Otol Rhinol Laryngol 6:987-1016, 1952). Posterior Semicircular Canal BPPV (PSCBPPV) has more incidence and prevalence then Lateral, and Anterior Semicircular Canal BPPV (Alghwiri et al. in Arch Phys Med Rehabil 93:1822-1831, 2012). Quality of life (QoL) is significantly impaired by vertigo (Sargent et al. in Otol Neurotol 22:205-209, 2001; World Health Organization in International classification of functioning, disability and health, World Health Organization, Geneva, 2001). To study the effect and compare Epley, Semont maneuvers and Brandt-Daroff Exercise on QoL in patients with PSCBPPV. 90 individuals with unilateral PSCBPPV were selected based on positive Dix-Hallpike test. 3 groups Epley, Semont, and Brandt-Daroff were formed and 30 individuals were selected in each group randomly. Dix-Hallpike test and Vestibular Activities and Participation (VAP) Scale based on International Classification of Functioning were administered before and after Epley, Semont maneuvers, and Brandt-Daroff Exercise to fulfill the aim. VAP Scale results revealed significant difference between pre and post treatment score in all 3 groups, suggestive of positive effect on QoL in patients with PSCBPPV. Improvements in VAP Score between 3 groups were compared and significant difference was observed. Dix-Hallpike test results revealed that 90, 73.33, and 50% patients improved in Epely, Semont, and Brandt-Daroff group respectively. Epely maneuver found to be the best choice and then Semont and Brandt-Daroff should be least preferred in treatment of patients with PSCBPPV. [ABSTRACT FROM AUTHOR]

With the exception of migraines, benign paroxysmal positional vertigo (BPPV) in patients with preexisting central neurologic disorders (CND) is rarely discussed in the literature. Demographic features of this patient group and the efficacy of repositioning therapy are still unknown. We hypothesized that a CND may alter the function of the central vestibular pathway, thus changing the pattern of BPPV and outcomes of repositioning. In this study, we enrolled 93 consecutive idiopathic BPPV patients and categorized them into two groups according to the presence or absence of a CND. In our series, 31.2% of BPPV cases had a CND. The most common associated CNDs were cerebrovascular disease and migraines. The two groups showed similar age distributions, canal involvement, success rates of repositioning, and cycles of treatment used to achieve complete resolution. The major differences were the proportion of females (89.7%) and a right-side predominance (75.9%) in the CND group. There was a trend of more residual dizziness (RD) after successful repositioning in the CND group, but the difference was not significant. The reason for the female and right-side predominance in the CND group is unclear. We concluded that the efficacy of repositioning therapy was excellent (with a success rate of 80.6% with one cycle and 93.5% within two cycles of treatment) for BPPV with or without a preexisting CND. Clinicians are encouraged to diagnose and treat BPPV in patients with a preexisting CND as early as possible to improve patients' quality of life, avoid complications, and reduce medical costs.

Benign paroxysmal positional vertigo (BPPV) is characterized by brief episodes of vertigo triggered by changes in head position caused by the displacement of otoliths from the utricle to the semicircular canals, particularly the posterior canal. This study explored the potential link between BPPV, the patient's preexisting conditions, and surgery-related factors including surgical positioning, duration of the procedure, exposure to vibratory forces, and anesthesia effects. This report presents two cases of BPPV following major joint replacement surgery. The first case involved a 65-year-old male with a history of diet-controlled diabetes who had undergone right-sided total hip replacement. The second case was that of a 60-year-old female with a history of osteoporosis managed with bisphosphonate therapy and left-sided knee replacement. Both patients developed vertigo symptoms one day postoperatively and were diagnosed with BPPV. In both cases, the Dix-Hallpike test confirmed the right-sided posterior canal BPPV diagnosis, and the patients were successfully treated using the Epley maneuver. Notably, there was no recurrence of vertigo at the four-week follow-up. These cases highlight the importance of considering BPPV in patients presenting with vertigo symptoms after joint replacement surgery, especially in the presence of comorbidities like diabetes and osteoporosis which possibly increase susceptibility to BPPV. This article presents two cases of benign paroxysmal positional vertigo (BPPV) following non-otologic surgery. It explores the pathophysiological mechanism underlying BPPV after such surgeries and also discusses the diagnosis and treatment approaches. This underscores the need for prompt diagnosis and treatment of BPPV to improve postoperative outcomes., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Bashir et al.)

OBJECTIVES: To evaluate short-term outcome for posterior canal benign paroxysmal positional vertigo (p-BPPV) after modified Epley's maneuver (mEM). MATERIALS and METHODS: Patients who were diagnosed with p-BPPV between September 2017 and January 2018 in a tertiary care center were included. Patients were treated with mEM. Five follow-up points were set at one hour, two hours, one day, three days and one week. If Dix-Hallpike test (DH) was positive, mEM was performed and patient was scheduled for follow-up at the next follow-up point. If negative, the patient was accepted as completely resolved and scheduled for follow-up at one week. The proportion of completely resolved patients at each follow-up point, recurrence, lateral canal conversion rate and time were noted. A retrospective control group was created from patients treated for p-BPPV between April and August 2017. The outcome of the study and control groups were compared. RESULTS: There were 93 patients in study group. 63 (67.7%), 8 (8.6%), 3 (3.2%), 0 (0%) and 9 (9.7%) patients completely resolved at one-hour, twohour, one-day, three-days and one-week follow-ups. 1.96±1.60 (1-5) mEMs were performed. Control group included 61 patients. At one-week follow-up a total of 83 (89.2%) patients in study group and 48 (78.7%) in control group were completely resolved(p=0.1043). In study group 5 (5.37%) of patients had lateral canal conversion within one day. 2(2.15%) had recurrence one day later after two-hour follow-up. The number of patients completely resolved at two-hour follow-up and before (76.34%) compared to the patients completely resolved at one-day follow-up and before (79.56%) were not significantly different (p=0.7235). CONCLUSION: Two-hour follow-up is equivalent to one-day follow-up of p-BPPV in terms of therapy outcome and adverse affects. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the feasibility and effectiveness of automated mechanical repositioning treatment (AMRT) for posterior canal benign paroxysmal positional vertigo (PC-BPPV). Patients and Methods: We reviewed all PC-BPPV patients admitted to our department between January and December 2016. The inclusion criteria mainly required conducting a diagnosis for PC-BPPV by using the Dix-Hallpike test, a PC-BPPV history within 1 month, no intake of medications for the last 48 h. Compared with the cases who received classical manual repositioning treatment (CMRT), the proportion of patients who underwent AMRT with a resolution within the 1-week follow-up session after initial treatment and a recurrence during the 6-month follow-up were evaluated. Results: A total of182 patients who underwent AMRT and 152 patients who underwent CMRT were included. Compared with the CMRT group, the AMRT group had a higher rate of complete or partial resolution and positional nystagmus at the 1 week follow-up (92.6 vs. 86.2%; p = 0.004). AMRT with less treatment cycles was more effective than CMRT (1.5 vs. 1.9; p < 0.001). After 6 months of follow-up, the cumulative recurrence rate of the AMRT group was significantly lower than that of the CMRT group (3.0 vs. 8.9%; p = 0.037). Conclusion: AMRT is a feasible and effective procedure for the resolution of PC-BPPV. [ABSTRACT FROM AUTHOR]

Benign paroxysmal positional vertigo (BPPV) is the most frequent type of vertigo. The treatment of canalithiasis of the posterior semicircular canal consists in performing a particle-repositioning maneuver, such as the Epley maneuver (EM). However, the EM is not effective in all cases. The objective of this study is to identify risk factors, which predict the EM failure, among the clinical variables recorded in anamnesis and patient examination. This is an observational prospective multicentric study. All patients presenting with BPPV were recruited and applied the EM and appointed for a follow-up visit 7 days later. The following variables were recorded: sex, age, arterial hypertension, diabetes, hyperlipidemia, smoking habit, alcohol consumption, migraine, osteoporosis, diseases of the inner ear, previous ipsilateral BPPV, previous traumatic brain injury, previous sudden head deceleration, time of evolution, sulpiride or betahistine treatment, experienced symptoms, outcome of the Halmagyi maneuver, laterality, cephalic hyperextension of the neck, intensity of nystagmus, intensity of vertigo, duration of nystagmus, occurrence of orthotropic nystagmus, symptoms immediately after the EM, postural restrictions, and symptoms 7 days after the EM. Significant differences in the rate of loss of nystagmus were found for six variables: hyperlipidemia, previous ipsilateral BPPV, intensity of nystagmus, duration of nystagmus, post-maneuver sweating, and subjective status. The most useful significant variables in the clinical practice to predict the success of the EM are previous BPPV and intensity of nystagmus. In the other significant variables, no physiopathological hypothesis can be formulated or differences between groups are too small. [ABSTRACT FROM AUTHOR]
