Real-Time Dynamic Imaging Study of Normal Pharyngolaryngeal Structures During Barium Swallow (GLAM-III)

NCT07264322 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 3

Last updated 2025-12-04

No results posted yet for this study

Summary

The integrity and functional stability of pharyngolaryngeal anatomical structures are critical for airway management, and the dynamic changes of key structures (e.g., pyriform sinus, cricoid cartilage lamina) during swallowing directly relate to the design and clinical safety of laryngeal masks. This observational study aims to investigate the real-time dynamic changes and physiological movement patterns of normal pharyngolaryngeal structures during barium swallow using routine barium meal examination imaging. The findings will provide anatomical and physiological evidence for optimizing laryngeal mask design and improving its anatomical fit with the pharynx and larynx.
