[Long-term efficacy observation of BPPV repositioning maneuver].

Objective: The aim of this study is to observe and analyze the long-term follow-up of the recurrence of benign paroxysmal positional vertigo BPPV with repositioning maneuver, and to determine the long-term therapeutic effect of repositioning maneuver. Method: To collect 738 patients who were diagnosed with BBPV due to vertigo. Follow up by telephone, SMS and other contact methods to analyze and summarize the long-term follow up of the recurrence of patients who had been treated with the appropriate repositioning maneuver. Result: Of the 738 patients, 458 patients were followed up and 280 were lost to follow up. The total follow up rate was 62.06%. 458 patients were followed up with 314 patients without recurrence and 144 patients with recurrence. The total recurrence rate was 31.44%. Conclusion: Repositioning maneuver is the most commonly used way for the treatment of BPPV. It is safe, simple and effective. However, patients with BPPV who have been cured by manual reduction still have a risk of recurrence. Among patients with relapse, the proportion of patients who relapsed once after treatment was the highest, and the recurrence rate of women with BPPV was significantly higher than that of men.
