Study Notes

Laryngeal Endoscopy

Laryngeal endoscopy, using flexible or rigid endoscopes, examines vocal fold structure and overall function.
Videostroboscopy analyzes vocal fold vibration patterns and the connection between the body and the cover of the vocal folds.
Laryngeal high-speed videoendoscopy adds detail by showing short and irregular vibration, enabling quantification of vibration parameters. This complements standard endoscopy and stroboscopy.
Narrow-band imaging (NBI) leverages tissue light absorption to visualize vascular details.

Visualization Techniques Summary

Various methods exist for visualizing and documenting laryngeal structure and function.
Each method (LVES, LHSV, and NBI) provides unique advantages and limitations.
Each technique contributes distinct information to a comprehensive assessment.
