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 کاملAir-pressure, Vocal Fold Vibration and Acoustic Characteristics of Phonation during Vocal Exercising. Part 1: Measurement in Vivo
The study investigates differences between three most widely used methods in voice training and therapy: Phonation into a resonance tube with the outer end in the air or submerged 2–10 cm in water (‘water resistance therapy’ with bubbling effect), and phonation into a very thin straw. One female speech trainer served as subject. Acoustic and electroglottographic (EGG) signals, and both mean and...
متن کاملModulating phonation through alteration of vocal fold medial surface contour.
OBJECTIVES/HYPOTHESIS 1) To test whether alteration of the vocal fold medial surface contour can improve phonation and 2) to demonstrate that implant material properties affect vibration even when implantation is deep to the vocal fold lamina propria. STUDY DESIGN Induced phonation of excised human larynges. METHODS Thirteen larynges were harvested within 24 hours postmortem. Phonation thre...
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 کاملStudy of resistance to Toxoplasmosis using Tachizoites surface antigens of Toxoplasma gondii in vivo
Taoxoplasma gondii is an important food-borne parasite transmitted primarily from animals to humans through meat consumption, mainly pork and lamb, as well as through oocysts shed by cats. Infection in humans can cause severe fetal malformations, ocular complications or encephalitis. Toxoplasmosis infection during pregnancy, especially in sheep, often results in abortion, representing considera...
