Abstract:
Objective:To analyze the application of video nystagmography in the diagnosis and treatment of benign paroxysmal positional vertigo (BPPV) so as to provide evidence for clinical diagnosis.Methods:A total of 120 patients with suspected BPPV who received treatment in Yueqing People's Hospital from January to July 2020 were included in this study. There were anterior ( n = 24), posterior ( n = 80) and horizontal semicircular canal ( n = 16) BPPV according to the disease type. The detection rates of anterior, posterior and horizontal semicircular canal BPPV by video nystagmography and naked eyes were determined. Therapeutic effects of video nystagmography on three types of BPPV were compared. Results:The diagnostic rates of anterior, posterior and horizontal semicircular canal BPPV were 91.68%, 92.50% and 93.75%, respectively, and the difference was not statistically significant ( χ2 = 0.06, P > 0.05). The detection rates of anterior, posterior and horizontal semicircular canal BPPV by video nystagmography were 91.68%, 92.50% and 93.75% respectively, which were significantly higher than those by naked eyes (58.34%, 78.75%, 56.25%, χ2 = 7.11, 6.14, 3.86, all P < 0.05). After 1 week of treatment, total response rates of anterior, posterior and horizontal semicircular canal BPPV were 62.50%, 66.25%, 68.75%, respectively. After 3 months of treatment, total response rates of anterior, posterior and horizontal semicircular canal BPPV were 95.83%, 96.25% and 100.00%, respectively. There were no significant differences between anterior, posterior and horizontal semicircular canal BPPV after 1 week and 3 months of treatment ( χ2 = 0.18, 0.64, P > 0.05). At 3 months after surgery, the recurrence rates of anterior, posterior and horizontal semicircular canal BPPV were 4.16%, 5.00% and 6.25%, respectively, and the difference was not statistically significant ( χ2 = 0.08, P > 0.05). Conclusion:Video nystagmography is highly effective in the diagnosis and treatment of BPPV. It can accurately judge the occurrence of nystagmus in BPPV and increase the detection rate, which is worthy of clinical application.
