OBJECTIVES We evaluated cross-linked hyaluronic acid (hylan B gel) as a scaffold for tissue regeneration and mucosal wave restoration in carbon dioxide laser-ablated canine vocal folds. METHODS Five beagles underwent stroboscopy before ablation of the left vocal fold with a carbon dioxide laser. Four weeks later, stroboscopy was repeated before and after submucosal injection of hylan B gel in...

A newly developed stroboscopy rating form is presented. The evolution of the new form is discussed by focusing on how problems with another commonly used form led to its development. Interjudge agreement and intrajudge reliability data for the new rating form reveal that the parameters of phase closure, phase symmetry, and phase regularity remain difficult to rate even with the revised rating f...

OBJECTIVES/HYPOTHESIS The term vocal fold nodules refers to bilateral thickening of the membranous folds with minimal impairment of the vibratory properties of the mucosa. Nodules are thought to be related to repetitive mechanical stress, associated with voice use patterns. Diagnosis is typically made in the office via either rigid or flexible laryngeal stroboscopy. Depending on the individual ...

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...

OBJECTIVES/HYPOTHESIS This study investigated the inter-rater and intrarater reliability of four basic visual perceptual parameters (lesion size rating and glottal configuration) in laryngostroboscopic evaluation. STUDY DESIGN Cohort Study. METHODS Two hundred fifty-five laryngostroboscopic video samples were evaluated by three raters on four measurements: 1) mass lesion size rating, 2) amp...
