Correlation Between Different Body Mass Index And Anatomical Position Of Tongue Artery

Objective:To compare the anatomical position of the lingual artery in people with different body mass index(BMI),whether there is any correlation between different body mass index,height,weight and tongue length,tongue width,bilateral lingual artery distance,lingual artery depth,so as to estimate the position of the tongue artery during the operation,so as to be able to to guide surgery.Methods:314 subjects who underwent CT angiography(computed tomography angiograph,CTA)in our hospital were randomly selected,and the subjects were divided into 4 groups according to different BMI values.Measure the subject’s tongue length,tongue width,bilateral lingual artery distance and lingual artery depth at each measurement point.The anatomical data of different gender in each group and anatomical data of lingual artery between groups were compared at the same time to find whether there is a significant difference.The next step is to analyze the correlation between BMI and various anatomical parameters.Results:Intra-group comparison: Only the height,weight,and lingual artery distance 10 mm before the reference point in the normal body weight group showed significant differences between men and women(P<0.05),and the age,height,weight,BMI values and the anatomical data of the tongue artery of different genders in the other groups has no significant difference(P>0.05).Comparison between groups: There was no significant difference in tongue width and bilateral lingual artery distance data at 3measurement points in each group(P>0.05),but significant difference in tongue length and lingual artery depth at each measurement point(P<0.05).Correlation analysis: BMI was significantly positively correlated with the bilateral lingual artery distance,lingual artery depth,and tongue length at each measurement point(r>0,P<0.05),and had no correlation with tongue width.Conclusion:In patients with different BMI values,the location of the lingual artery will be different and behave as positively correlated.When performing tongue surgery,individual surgical plans should be made according to patients with different BMI values to avoid damage to the lingual artery.
