Effect of sugarcane biopolymer gel injected in rabbit vocal fold.
INTRODUCTION Alterations in the vocal folds that involve volume reduction and glottal closure failure result in exaggerated air escape during speech. For such situations, the use of implants or grafts of different materials has been proposed. OBJECTIVE To define the effect of sugarcane biopolymer gel when implanted in the vocal folds of rabbits. METHODS This was an experimental study. The v...

متن کاملMonitoring 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 ...
