OBJECTIVE: To explore the clinical value of real-time ultrasound measurement of thyrohyoid space dynamics in assessing vocal hyperfunction mode (VHM).
MATERIALS AND METHODS: The 161 chronic laryngitis patients, 55 with vocal cord polyps, and 44 normal controls were studied at Sun Yat-sen Memorial Hospital, Sun Yat-sen University, from June 2024 to January 2025. Voice quality, aerodynamic parameters, and thyrohyoid space were assessed using VHI-10, GRBAS scale, voice analysis, aerodynamic profiling, palpation scoring, and ultrasound. Data analysis was conducted using Python.
RESULTS: Significant differences (p < 0.05) in VHI-10 scores, G, R, B, S, Jitter, and Shimmer are observed between male and female vocal cord polyp groups. Aerodynamic analysis indicates distinct variations in mean airflow rate across both genders (p < 0.05), while maximum phonation time and subglottic pressure differ significantly in females alone (p < 0.05). Palpation scores for the thyrohyoid space and F0 do not show substantial differences (p > 0.05) between groups. Conversely, real-time ultrasound evaluations of the thyrohyoid space, including pre-phonation/phonation minimum distances (left/right), rates of unilateral (left/right) narrowing, and maximum narrowing rate, exhibit notable differences (p < 0.05) across three groups.
CONCLUSION: Real-time ultrasound measurement of the thyroid-hyoid gap is simple, feasible, and provides a more quantitative assessment of VHM than subjective palpation or vocal aerodynamic measures. It therefore represents a useful clinical tool for evaluating voice function.
