Study on ultrasonographic morphology and stiffness of the geniohyoid muscle in middle-aged and elderly adults
摘要
Abstract
Objective To explore the application value of high-frequency ultrasound combined with shear-wave elastogra-phy(SWE)in quantitative evaluation of the morphology and stiffness of geniohyoid muscle in healthy middle-aged and elder-ly adults,so as to establish a non-invasive imaging method for assessing swallowing-related muscle function.Methods A total of 111 healthy volunteers aged 45 to 80 years were recruited from July 2023 to December 2024,including 54 males and 57 females.High-frequency ultrasound was used to measure the anterior-posterior diameter(D)and cross-sectional area(CSA)of geniohyoid muscle at its thickest point,and SWE technology was applied to measure its shear wave elastic Young's modulus(E).The intra-and inter-observer measurement repeatability of each parameter was evaluated by intraclass correlation coeffi-cient(ICC).Pearson correlation analysis and stepwise multiple linear regression analysis were performed to investigate the associations of D,CSA and E with age,gender and body mass index(BMI).Results The D([0.61±0.08]cm vs[0.54±0.07]cm)and CSA([2.06±0.48]cm2 vs[1.27±0.34]cm2)of geniohyoid muscle in the male group were significantly larger than those in the female group,and differences were statistically significant(all P<0.001).There was no statistically significant difference in E value between the two groups(P=0.088).The intra-and inter-observer ICCs of D,CSA and E were all greater than 0.9,indicating good measurement repeatability.Correlation analysis showed that D and CSA were nega-tively correlated with age(r=-0.54,-0.59,all P<0.001)and positively correlated with BMI(r=0.66,0.47,all P<0.001).E was positively correlated with BMI(r=0.50,P<0.001).Stepwise multiple linear regression analysis showed that both D and CSA were independently correlated with BMI and gender(all P<0.001),and had no independent associa-tion with age.E was only independently correlated with BMI(P<0.001).Conclusion High-frequency ultrasound com-bined with SWE enables stable and reproducible quantification of the morphology and stiffness of the geniohyoid muscle in middle-aged and elderly adults.Morphological parameters(D and CSA)are significantly associated with age and BMI,while the stiffness parameter(E)is significantly positively correlated with BMI,and this approach is expected to provide objective quantitative imaging indicators for clinical assessment of swallowing function.关键词
