Study On The Characteristics Of Benign Paroxysmal Positional Vertigo And The Influencing Factors Of Short-term Residual Symptoms After Reposition Treatment

Objective : The objective of this article is to study the characteristics of benign paroxysmal positional vertigo(BPPV)and the influencing factors of residual symptoms after otolith repositioning therapy,so as to provide references for clinical diagnosis and treatment.Methods:From June to November in 2017,568 patients with BPPV were diagnosed and treated in otolaryngology out-patient clinics of the First Affiliated Hospital of China Medical University.All of these patients were followed up after 1 month,and we can summarize the amount of residual symptoms.The age,sex,type of disease,etiological factor and the condition of internal medicine were compared with residual symptom ones and no residual symptom ones.All data were statistically analyzed by SPPS22.0 software.Results:The age range was 12~92 years,and the average age of onset was(54.89 +13.056)years.The proportion of men and women is 1:2.74,and the number of middle aged and elderly women at the age of 45~65 is the highest,up to 74.4%.The posterior semicircular canal accounts for about 55.6%,the horizontal semicircular canal accounts for about 22.6%,and the two kinds of semicircular canals are involved in about 21.8%.Primary BPPV accounted for about 90.67% and secondary BPPV accounted for about 9.33%.Secondary BPPV patients had more trauma and middle ear surgery.After reduction,there were 98 remnants of dizziness and balance disorder.There was no significant difference between the P > 0.05 and the difference between the different sex,the cause and the incidence of the disease.Whether the age is more than65 years old,whether or not accumulative semicircular canals,whether the combination of related internal medical diseases is compared,P < 0.05,the difference is statistically significant.Conclusions:The residual symptoms such as dizziness and balance disorder are easy to occur after otolith reduction in patients with older,multi-semi-conventional tube and associated internal medical diseases.Correct guidance and education should be carried out for the patients,and the training of the vestibule rehabilitation should be instruct.
