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 کاملThe Effects of Size and Type of Vocal Fold Polyp on Some Acoustic Voice Parameters
Background: Vocal abuse and misuse would result in vocal fold polyp. Certain features define the extent of vocal folds polyp effects on voice acoustic parameters. The present study aimed to define the effects of polyp size on acoustic voice parameters, and compare these parameters in hemorrhagic and non-hemorrhagic polyps.Methods: In the present retrospective study, 28 individuals with hemorrha...
متن کاملInfluence of vocal fold stiffness and acoustic loading on flow-induced vibration of a single-layer vocal fold model.
The flow-induced vibrations of a single-layer vocal fold model were investigated as a function of vocal fold stiffness, and subglottal and supraglottal acoustic loading. Previously, it was reported that the single-layer vocal fold model failed to vibrate when short, clinically-relevant tracheal tubes were used. Moreover, it was reported that the model had a propensity to be acoustically driven,...
متن کاملThe diagnostic role of high-speed vocal fold vibratory imaging.
OBJECTIVE Although high-speed imaging (HSI) has been identified as a valuable tool in phonatory biomechanics research, to date, there have only been a selected number of reports investigating the clinical utility of HSI. We aim to elucidate the role of HSI in the diagnosis of the dysphonic patient. METHODS The video files from 28 consecutive dysphonic patients with concurrently acquired video...
