Monitoring vocal fold abduction through vocal fold contact area.
A number of commercial devices for measuring the transverse electrical conductance of the thyroid cartilage produce waveforms that can be useful for monitoring movements within the larynx during voice production, especially movements that are closely related to the time-variation of the contact between the vocal folds as they vibrate. This paper compares the various approaches that can be used ...
متن کاملQuantitative laryngeal electromyography assessment of cricothyroid function in patients with unilateral vocal fold paralysis.
OBJECTIVES/HYPOTHESIS Determination of superior laryngeal nerve (SLN) involvement in addition to recurrent laryngeal nerve (RLN) paralysis in patients with unilateral vocal fold paralysis (UVFP) relies on traditional, qualitative laryngeal electromyography (LEMG) examination. It is necessary to develop a quantitative measurement that reflects the degree of denervation of the cricothyroid (CT) m...
متن کاملEndoscopic assessment of vocal fold movements during cough.
OBJECTIVES Little is known about the function of the true vocal folds (TVFs) during cough. The objective of this study was to determine the reliability of measuring TVF movements during cough and to obtain preliminary normative data for these measures. METHODS Sequential glottal angles associated with TVF adduction and abduction across the phases of cough were analyzed from laryngeal videoend...
متن کاملObjective vocal fold vibration assessment from videokymographic images
Vocal folds oscillation crucially influences all the basic qualities of voice, such as pitch and loudness, as well as the spectrum. Stroboscopy provides the standard view of the larynx. Videokymography is a new diagnostic tool developed to overcome specific limitations of stroboscopy in severely dysphonic patients with an aperiodic signal. It registers the movements of the vocal folds with a hi...
متن کاملPaediatric vocal fold paralysis.
INTRODUCTION AND OBJECTIVES Vocal fold paralysis (VFP) is a relatively common cause of stridor and dysphonia in the paediatric population. This report summarises our experience with VFP in the paediatric age group. METHODS All patients presenting with vocal fold paralysis over a 12-month period were included. Medical charts were revised retrospectively. The diagnosis was performed by flexible...
