Abstract:
Objective To explore the characteristics of the cross-sectional area(CSA)of the vagus nerve in a healthy population in Qujing,Yunnan,and its correlation with demographic characteristics.Methods High-resolution nerve ultrasound examinations were conducted on the vagus nerve of 201 healthy volunteers from a hospital in Qujing,Yunnan from September 2022 to March 2023.The CSA was measured through transverse scans of the vagus nerve.The correlation of vagus nerve CSA with age,body mass index(BMI),and gender was assessed.Results The mean CSA of the bilateral VN were 1.9 mm2(right)and 1.3 mm2(left),respectively.The average CSA of the right vagus nerve was significantly greater than that of the left(P<0.001).In the high-age group(>50 years),the average CSA of the right vagus nerve was significantly higher than that of the low-age group(≤50 years)(P=0.0142).However,there was no statistically significant difference in the average CSA of the right vagus nerve between the BMI>24 kg/m2 group and the≤24 kg/m2 group(P=0.0852).The average CSA of the left vagus nerve showed no statistically significant differences across different age groups and BMI groups(P>0.05),but the average CSA of the bilateral vagus nerve in the male group was greater than that in the female group,with a statistically significant difference(P<0.05).Correlation analysis further confirmed a negative correlation between the average CSA of the right vagus nerve and age(r=-0.17,P=0.0139).Multiple linear regression models indicated that age(P=0.007)and gender(P=0.001)were independent influencing factors for the average CSA of the right vagus nerve.Conclusion In the healthy population of Qujing,Yunnan,the CSA of the right vagus nerve is significantly greater than that of the left,and males also exhibit a significantly greater CSA than females.With increasing age,the vagus nerve gradually becomes thinner.
