Will present a talk titled:
Vocal Fold Damage due to Compensation for Voice Disorders: Investigating Collision Pressure and Dissipated Power in Synthetic Models
Abstract: The production of voiced speech is generated by the vibration of the vocal folds, which are two elastic bands of tissue stretching across the airway. As airflow from the lungs passes through the vocal folds, they oscillate and create a pulsatile pressure field, which is the origin of human voice. Vocal fold pathologies may lead to deficiencies in voice production, and compensating for these deficiencies can create excessive stresses during vocal fold collision, worsening the underlying condition. This presentation focuses on experimental studies investigating the damaging effects of compensating for voice insufficiency due to two main vocal fold disorders, posterior glottal opening and vocal fold nodules. Two measures of VF injury, collision pressure and dissipated collision power, were investigated in synthetic silicone vocal fold models, representing both healthy and pathological conditions, by measuring the collision pressure distribution and oscillation kinematics. The clinical implications of the results are also discussed.
