良性阵发性位置性眩晕患者七年大数据回顾分析OA北大核心CSTPCD

Objective Benign paroxysmal positional vertigo(BPPV)is the most common peripheral vestibular disease.However,there lacks large sample data analysis on BPPV in China.This current study aims to provide data sup-port for family counseling and prevention of BPPV.Methods Records of patients with vertigo(n=45 807)seen at the Chinese PLA General Hospital in the past 7 years,including patients with confirmed BPPV(n=5883)were retrospective-ly reviewed.Key information,including age,gender,visit time,initial BPPV type and BPPV type at follow-ups,were analyzed.Data were visualized using the Python 3.7 software.Result Of the 5883 patients with confirmed BPPV,the fe-male to male ratio was 1.98:1(3909:1,974),mostly in the age range of 50-59 years,with more female patients than male patients in all BPPV types.Among all 45 808 vertigo patients,12.8%were positive for positional nystagmus.Pos-terior semicircular canal BPPV was the most common(64.5%),followed by horizontal canal BPPV(30.9%).Follow-up records were for 1092 patients,showing disappearance of BPPV in 411 patients and change of BPPV type in 234 pa-tients(most often between left and right posterior canal BPPV,n=71).Conclusions Our data show that BPPV was main-ly seen in women around 50 years of age.The rate of lateral canal BPPV was higher in this group than previously report-ed at 30.9%.Long-term follow-ups showed a main pattern of BPPV type changes of switching sides in patients with pos-terior canal BPPV and switching between posterior canal and horizontal canal BPPV.
