Item type:Publication, Comparison of Treatment Results for Clinical Types of Benign Paroxysmal Positional Vertigo(Mongolian National University of Medical Sciences, 2021-07-01); ; ; ; Objective: To compare the clinical characteristics and treatment results of different clinical types of benign paroxysmal positional vertigo (BPPV). Methods: A total of 162 patients diagnosed with BPPV between January 2019 to January 2021 at EMJJ ENT Hospital’s vestibular laboratory in Mongolia were included in our study. The diagnosis of BPPV was made according to the 2017 AAO-HNS clinical practice guideline for BPPV. Clinical questionnaires, Dizziness Handicap Inventory (DHI) questionnaires, and videonystgamography were obtained for all patients. Results: From a total of 162 patients diagnosed as BPPV, 62.4% had posterior canal BPPV, 27.1% had horizontal canal BPPV, and 10.5% had anterior canal BPPV. Fischer’s exact test showed a higher incidence on the right side (p = 0.000). The mean age 50 ± 11.7; the male to female ratio 1:4. When the relationship between the effectiveness and duration of the treatment was assessed, 123 (75.9%) recovered after 7 days. DHI score after treatment significantly after treatment (p = 0.000) regardless of the clinical type. Conclusions: Patients who had a longer duration of symptoms underwent unnecessary diagnostic tests and developed additional psychologic problems. There were no statistically significant differences when we compared the characteristics and treatment between the three clinical types of BPPV. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Unnecessary magnetic resonance imaging is associated with diagnostic delay and financial burden in benign paroxysmal positional vertigo: a retrospective study in Mongolia(2026); ; ; INTRODUCTION: This single-center, retrospective cohort study investigated the clinical characteristics, diagnostic pathways, and economic burden of benign paroxysmal positional vertigo (BPPV) at a national tertiary referral ENT hospital in Ulaanbaatar, Mongolia. METHODS: We analyzed 162 patients (mean age, 50.0 ± 11.7 years) with confirmed BPPV who completed follow-up between January 2019 and January 2021. Patients were treated with canalith repositioning procedures and instructed to perform self-maneuvers. The primary outcome was symptom resolution at 7, 14, and 28 days, and the secondary outcome was the change in Dizziness Handicap Inventory (DHI) scores. RESULTS: Results showed that 102 patients (62.5%) were referred from other hospitals, yet only 6 (3.7%) were correctly diagnosed prior to referral. Multivariate logistic regression identified no specific clinical symptoms predicting magnetic resonance imaging (MRI) usage, suggesting that neuroimaging was largely driven by patient-initiated demand in the private sector. The mean diagnostic delay was significantly longer in the MRI group (24.4 ± 19.5 days) compared to the non-MRI group (7.5 ± 5.9 days, p < 0.001). Cost analysis based on 2024 metrics revealed that a single potentially low-yield MRI consumes 72.0% of a minimum-wage worker's monthly income, creating a catastrophic financial burden. Treatment was highly effective, with resolution rates of 75.9, 93.8, and 99.4% at 7, 14, and 28 days, respectively. The mean DHI score improved significantly from 39.93 to 4.12 (p < 0.001). DISCUSSION: BPPV patients in Mongolia face significant diagnostic delays and high misdiagnosis rates. While standardized maneuvers are effective, the reliance on costly imaging highlights an urgent need for educational initiatives to improve awareness and primary care triage in developing countries.Scopus© Citations 1
