OBJECTIVES/HYPOTHESIS: Our laboratory has developed an in vivo rabbit model to investigate the effects of phonation on expression and turnover of the vocal fold extracellular matrix. As a logical outg...
OBJECTIVES/HYPOTHESIS: Phonation threshold flow (PTF) may provide a tool to assess laryngeal function and could differentiate between normal and pathological voices. Both polyps and nodules contribute...
The purpose of this study was to determine the average phonation time, phonation volume and air flow rate, as well as the relationship between each of these parameters during two conditions (normal an...
CONCLUSIONS: Tracheoesophageal phonation appears to participate in early acquisition of esophageal phonation, which remains the preferred method of voice restoration among patients. Further studies in...
OBJECTIVE/HYPOTHESIS: Most methods to measure phonation threshold pressure (PTP) are clinically impractical because they are invasive. This report concerns an airflow interruption system developed to ...
