In vivo vocal fold cover layer replacement.
OBJECTIVES/HYPOTHESIS An animal vocal fold replacement model is needed to investigate treatments for vocal fold scarring. We developed a rabbit surgical model, hypothesizing that orthotopic vocal fold cover implants would attach and survive. We further hypothesized that superficial scarring would be limited, allowing unimpeded vibration. STUDY DESIGN Translational research: animal surgical st...
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 ...
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...
متن کاملVideostroboscopy of human vocal fold paralysis.
Previous stroboscopic studies of human vocal cord paralysis have been infrequent and have lacked documentation of the site of lesion. In order to study human laryngeal paralysis, the recurrent and superior laryngeal nerves were infiltrated unilaterally with lidocaine hydrochloride in three human volunteers. Vagal paralysis was simulated by combined (superior and recurrent) infiltration in one v...
متن کاملControl of Vocal Fold Cover Stiffness by Laryngeal Muscles
Objectives: The objective of this study is to perform preliminary measurements of the shear modulus of the vocal fold cover layer during intrinsic laryngeal muscle contraction. Study Design: Shear modulus was measured in an ex vivo human larynx and an in vivo canine larynx. Methods: A modified linear skin rheometer adapted for laryngeal viscoelasticity measurement applied shear stress to the mi...
