Evaluation of the Distance Between Anterior Commissure of True Vocal Folds and the First Tracheal Ring and Related Laryngeal Indices in 40 Human Cadavers
Journal of Voice (2016) Vol. 30, No. 2, pp. 158-160

Distorted anatomy in laryngotracheal pathologies expresses the need to determine a quantitative mean of the distance between the anterior commissure of true vocal folds and the first tracheal ring to better define whether a lesion is in the subglottis or ...

Vocal Fold Vibratory Changes Following Surgical Intervention
Journal of Voice (2016) Vol. 30, No. 2, pp. 224-227

High-speed videoendoscopy (HSV) captures direct cycle-to-cycle visualization of vocal fold movement in real time. This ultrafast recording rate is capable of visualizing the vibratory motion of the vocal folds in severely disordered phonation and provides a direct method for examining ...

Cricothyroid Muscle Botulinum Toxin Injection to Improve Airway for Bilateral Recurrent Laryngeal Nerve Paralysis, A Case Series
Journal of Voice (2016) Vol. 30, No. 1, pp. 96-99

Bilateral vocal fold paralysis most commonly results from iatrogenic trauma to the recurrent laryngeal nerve during surgical procedures in the anterior neck. Patients may require tracheostomy because of acute or gradual onset of dyspnea and airway compromise. The intralaryngeal injection ...

Relationship of Various Open Quotients With Acoustic Property, Phonation Types, Fundamental Frequency, and Intensity
Journal of Voice (2016) Vol. 30, No. 2, pp. 145-157

In the present study, we examined the relationship between various open quotients (Oqs) and phonation types, fundamental frequency (F0), and intensity by multivariate linear regression analysis (MVA) to determine which Oq best reflects vocal fold vibratory characteristics. Using high-speed digital ...

Relationship Between the Electroglottographic Signal and Vocal Fold Contact Area
Journal of Voice (2016) Vol. 30, No. 2, pp. 161-171

Electroglottography (EGG) is a widely used noninvasive method that purports to measure changes in relative vocal fold contact area (VFCA) during phonation. Despite its broad application, the putative direct relation between the EGG waveform and VFCA has to date only ...

Use Videostrobokymography to Quantitatively Analyze the Vibratory Characteristics Before and After Conservative Medical Treatment of Vocal Fold Leukoplakia
Journal of Voice (2016) Vol. 30, No. 2, pp. 215-220

Objectives: To quantitatively analyze the vibratory characteristics of vocal folds before and after conservative treatments to evaluate the outcomes of conservative treatments for vocal fold leukoplakia using videostrobokymography (VSK). Twenty patients and 20 controls were enrolled into the study. All ...

The First Application of the Two-Dimensional Scanning Videokymography in Excised Canine Larynx Model
Journal of Voice (2016) Vol. 30, No. 1, pp. 1-4

Evaluation of the vibratory pattern of vocal folds is of paramount importance to diagnose vocal fold disorders. Currently, laryngeal videokymography (VKG) and digital kymography from high-speed videolaryngoscopy are the available techniques for studying aperiodic vibrations of vocal folds. But VKG ...

In-Office Excision En Masse of a Vocal Process Granuloma Using the Potassium-Titanyl-Phosphate Laser
Journal of Voice (2016) Vol. 30, No. 1, pp. 93-95

In-office laryngeal surgery is taking on a more commonplace role in the treatment of laryngeal disorders. The potassium-titanyl-phosphate (KTP) laser has been a resourceful adjunct to the management of patients with mucosal lesions of the vocal cords. However, a paucity ...

Fracture Toughness of Vocal Fold Tissue: A Preliminary Study
Journal of Voice (2016) Vol. 30, No. 3, pp. 251-254

A customized mechanical tester that slices thin, soft samples was used to measure the fracture toughness of vocal fold tissue. Porcine vocal fold lamina propria was subjected to quasi-static, guillotine-like tests at three equally distanced regions along the anterior-posterior direction. ...

Features of Vocal Fold Adductor Paralysis and the Management of Posterior Muscle in Thyroplasty
Journal of Voice (2016) Vol. 30, No. 2, pp. 234-241

Objective: To present the pathologic characteristics of unilateral recurrent nerve adductor branch paralysis (AdBP), and to investigate the management of posterior cricoarytenoid (PCA) muscle on the basis of our experience of surgical treatment for AdBP. Four cases of AdBP, in ...
