Abstract
Objective: To elucidate the imaging characteristics of and establish reference values for measurement parameters of the vocal cords in healthy volunteers.
Methods: A total of 1000 healthy Han Chinese adults (694 women) aged 18-79 y will be enrolled between October 2023 and April 2024. The length and width of vocal cord abduction and adduction and vocal cord thickness were measured, and the widening and shortening rates of vocal cord adduction were calculated as indicators of vocal cord motor function. The data were stratified by age group and sex. The correlations of vocal cord measurements with age, height, weight, BMI and BSA were analyzed.
Results: The parathyroid section clearly revealed the vocal cord structure. Image quality decreases with age. Normal reference ranges (from the 2.5th to the 97.5th percentile) were established for vocal cord abduction length, adduction length, abduction width, adduction thickness, shortening rate and broadening rate based on data from 638 healthy adults: males: 13.98-28.17 mm, 11.33-21.21 mm, 2.90-5.66 mm, 5.65-7.44 mm, 3.16-6.18 mm, 9.97%-44.31% and 14.13%-137.78%, respectively; females: 12.55-19.42 mm, 9.59-14.80 mm, 3.40-4.80 mm, 5.65-7.90 mm, 3.40-4.90 mm, 10.05%-39.34% and 32.88%-102.66%, respectively. Vocal cord length, width, thickness, shortening rate and broadening rate were not correlated with age, height, weight, BMI or BSA.
Conclusion: This study summarized the characteristics of and initially established reference values for quantitative parameters of the vocal cords, ultimately providing reference values for the clinic.
期刊介绍：
Ultrasound in Medicine and Biology is the official journal of the World Federation for Ultrasound in Medicine and Biology. The journal publishes original contributions that demonstrate a novel application of an existing ultrasound technology in clinical diagnostic, interventional and therapeutic applications, new and improved clinical techniques, the physics, engineering and technology of ultrasound in medicine and biology, and the interactions between ultrasound and biological systems, including bioeffects. Papers that simply utilize standard diagnostic ultrasound as a measuring tool will be considered out of scope. Extended critical reviews of subjects of contemporary interest in the field are also published, in addition to occasional editorial articles, clinical and technical notes, book reviews, letters to the editor and a calendar of forthcoming meetings. It is the aim of the journal fully to meet the information and publication requirements of the clinicians, scientists, engineers and other professionals who constitute the biomedical ultrasonic community.
