Clinical Analysis Of 228 Cases Of Benign Paroxysmal Positional Vertigo In The Outpatient Department Of Neurology

Objective:Tocollect and analyze the clinical data of the patients with the benign paroxysmal positional vertigo(BPPV)inthe Department of Neurology in order to reduce the missed diagnosis and misdiagnosis of BPPV.Method:From January 2017 to March 2017 in the first hospital of Jilin University Bethune neurology clinic 228 cases of benign paroxysmal positional vertigo patients and related information werecollected.This included gender,age,time duration,inducement,relieve dizziness,reduction treatment,treatment side effects and other indicators.The clinical data werecollected and then analyzed statistically.Result:(1)592 patients were diagnosed with parallel vertigo after being examined in No.1 Hospital of Jilin University,of which 228 cases(38.51%)were diagnosed as BPPV.(2)In BPPV patients,the proportion of men and women was 1:2.(3)The youngest patients with BPPV was 17-year-old,the oldest was76-year-old,the average age of onset was 52.62 years old,and the incidence of the disease was mainly 40-69 years old.There was a significant difference in age amongbenign paroxysmal positional vertigo patients(P<0.05).(4)Atotal of 165 cases(72.36%)of the posterior semicircular canal(BPPV),5 cases(2.19%)of the anterior semicircular canal(BPPV),47 BPPV in the horizontal semicircular canal(20.61%),and 11 of mixed BPPV(4.82%)were found.(5)Vertigo of 143 cases induced and aggravated with rise,bow,get up,lay down positions in patients with PC-BPPV(86.67%);left turn and right turn(or)couldinduce and aggravate vertigo in 39 cases of HC-BPPV patients(82.97%);Vertigo induced by rise,bow action in SC-BPPV patients,and was aggravated in 4 cases with getting up,laying down position(80%).(6)The vertigo duration in 209 cases(91.67%)was recorded froma few seconds to 1 minute;the vertigo time in 19 patients(8.33%)lasted from 1 minute to 10 minutes.The difference in the duration of vertigo was statistically significant in the benign paroxysmal positional vertigo(P<0.05).(7)BPPV patients were treated with reduction and the total effective rate(including recovery and improvement)was 96.27%.Conclusion:In the patients with benign paroxysmal positional vertigo(BPPV),there were fewer men than women,and the group between the age of 40 to 69 years old had a high incidence of BPPV.The proportion of various types of BPPV patients from high to low was PC-BPPV,HC-BPPV,mixed semicircular canals BPPV,SC-BPPV.The clinical manifestation of BPPV in patients is determined mainly by the rotation of the visual objects related to the body position,and the duration being less than one minute.The earlier a patient is diagnosed and treated,the better the prognosis.
