Abstract:
Objective:To analyze the influencing factors of image quality of high-frequency ultrasound at the level of the glottis in healthy adults.Methods:A cross-sectional study was conducted on 433 healthy voluteers who underwent routine neck ultrasound examination at the Second Affiliated Hospital of Xi'an Jiaotong University from October 2023 to April 2024 and met the inclusion criteria. General data of the subjects were collected，and the image quality was graded. Gender，age，height，weight，body mass index，body surface area，thyroid cartilage calcification ratio，thickness of anterior cervical subcutaneous soft tissue and thickness of anterior cervical muscle group were analyzed by using multivariable Logistic regression for the influencing factors of image quality.Results:The display rates of the vocal cord epithelial layer and lamina propria，vocal cord muscle layer and paraglottic space structures in the para-thyroid cartilage section were superior to those in the anterior median section，with statistically significant differences（all P<0.05）. There were statistically significant differences in image quality grading among different age groups（all P<0.05），and image quality deteriorated as age increased. Logistic multivariate analysis indicated that gender，age and thyroid cartilage calcification ratio were independent factors affecting image quality（all P<0.05）. With age increased，thyroid cartilage calcification at the glottic level could be concentrated in the anterior，middle and posterior parts，respectively，and subsequently，calcification in the anterior and middle or middle and posterior parts gradually fused until complete calcification occurred. Conclusions:High-frequency ultrasound can clearly display the structures of most normal adult larynges at the glottis level，with the lateral section of the thyroid cartilage being superior to the median anterior neck section. As age increases，the degree of thyroid cartilage calcification increases，and image quality worsens.
