- Abstract
Objective: To analyze the characteristics of patients with benign paroxysmal positional vertigo which were spontaneously cured. Method: A total of 1 257 patients with chief complaint of positional vertigo were included and analyzed retrospectively, in which 921 cases were diagnosed as BPPV with the diagnosis standard of Guiyang meeting, and the other 336 cases were negative in the positional test diagnosed as BPPV-spontaneously cured. The age,gender and history course of the two groups were analyzed respectively. Result: ①Among the 1 257 cases of BPPV, 336 (111 male and 225 female) were diagnosed as BPPV-spontaneously cured, with total self remission rate of 26.7%. And the female self remission rate is lower than men slightly(25.9% vs 28.5%).②The ratio of male to female was 1∶2 in patients with BPPV-spontaneously cured and 1∶2.3 in patients with BPPV. Patients of the two groups were mostly female, and there was no significant difference in gender distribution. ③There was no significant difference in age distribution between patients of BPPV-spontaneously cured and BPPV, and patients of >50-70 years old were common in both groups.④The history course of patients in BPPV-spontaneously cured and BPPV both were mostly within 2 weeks at their first visit to hospital,each accounting for 75.3% and 69.3%.But the ratio of patients with BPPV-spontaneously cured for 1-2 weeks was higher than that of the BPPV (20.5% vs 15.1%), and the difference was statistically significant. Conclusion: Whether patients with BPPV can cure spontaneously is not related to age or gender, while women may have a tendency of lower self remission rate. The natural course of patients with BPPV-spontaneously cured is mostly within 2-4 weeks. The duration of natural course may be related to the type of semicircular canal involved.
