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, Treatment Results of Definite and Probable Meniere's Disease(Mongolian National University of Medical Sciences, 2021-04-01); ; ; ; Objectives: To evaluate the treatment results of definite and probable Meniere's disease (MD). Methods: A total of 51 patients, who were diagnosed with Meniere's disease (MD) between January 2019 to January 2021 at EMJJ ENT hospital's vestibular laboratory in Mongolia, was included in our study. The diagnosis of Meniere's disease was according to the 2015 Diagnostic criteria of Meniere's disease of the Classification Committee of the Barany Society. The clinical dizziness handicap inventory (DHI) questionnaire was taken, and videonystagmography (VNG), caloric test, and PTA was done in all patients. Results: Of a total of 51 patients, 9 were diagnosed as probable MD, and 42 were diagnosed as definite MD. The mean age of the patients was 43.7, male to female ratio was 1:1.8, 37 (72.5%) patients were in treatment group I who all received medication only, and 14 (27.5%) patients were in treatment group II who were refractory to prior medical therapy underwent ITDL Comparing the two treatment groups, there were significant differences in all test results (p = 0.000). After ITDI hearing improved (p = 0.000). Conclusions: VNG, caloric test, and DHI questionnaire results show that both medical treatment and ITDI are successful in improving vestibular function. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Байршлын хамааралт хоргүй толгой эргэлтийн эмнэлзүйн хэлбэрүүдийг харьцуулсан судалгаа(2021-04-06); ; ; Үндэслэл: Байршлын хамааралт хоргүй толгой эргэлтийн тархалт 100.000 хүн ам тутамд 10.7-оос 140 тохиолддог. Монголд 2016 онд тэнцвэрийн лаборатори байгуулагдаж, эмнэлзүйн 3 хэлбэрийг ялган оношлож эхэлсэнч тодорхой судалгаа хийгдээгүй байгаа юм. Зорилго: Байршлын хамааралт хоргүй толгой эргэлтийг эмнэлзүйн хэлбэрээр ялган оношлох, хооронд нь харьцуулахад оршино. Арга аргачлал: Аналитик загварын агшингийн арга ашигласан. 2019-2021 онд ЭМЖЖ эмнэлгийн тэнцвэрийн лабораторид ирсэн 162 үйлчлүүлэгчдийг хамруулсан. AAO-HNSF-аас 2017 онд гаргасан Байршлын хамааралт хоргүй толгой эргэлтийн эмнэлзүйн удирдамжийн дагуу оношлов. Эмнэлзүйн шалгуур асуумж болон видеонистагмографи багажийг ашигласан. Үр дүн: Нийт 162 үйлчлүүлэгчээс арын тал цагиргийн 101 (62.4%), хажуугийн тал цагиргийн 44 (27.1%), урд тал цагиргийн 17 (10.5%) үйлчлүүлэгч байна. Дундаж нас 50, хүйсийн харьцаа эр 32, эм 130, 1:4. Шалтгаангүй 80 (49.4%), гэмтэл, доргилтын шалтгаантай 40 (24.7%). Эмнэлэгт үзүүлээд ирсэн 102 үйлчлүүлэгчээс BPPV оношлогдсон 5.8%. Эмнэлзүйн 3 хэлбэрийг харьцуулахад нас, хүйс, үргэлжилсэн хугацаа, сэдрэлийн тоо, шалтгаан зэрэгт статистик ач холбогдол бүхий ялгаагүй. Дүгнэлт: Байршлын хамааралт хоргүй толгой эргэлтийн 3 эмнэлзүйн хэлбэрийг нас, хүйс, сэдрэлийн тоо, үргэлжилсэн хугацаа, шалтгаан, шаардлагагүй шинжилгээ зэргээр харьцуулан судлахад статистик ач холбогдол бүхий ялгаа гарсангүй. - 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
