Pearson correlation analysis was used for normal distribution data, spearman correlation analysis was for skew distribution data, r > 0.3. Measurements with strong correlation were extracted and displayed in a bold font

TA, temporal muscle; MM, masseter muscle; DA, anterior digastric; UO, upper orbicularis; ME, mentalis muscle
