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 ...

Leiomyosarcoma of Larynx as a Metachronous Tumor of Squamous Cell Carcinoma: An Unusual Case
Journal of Voice (2016) Vol. 30, No. 2, pp. 242-245

Leiomyosarcomas (LMSs) are malignant tumors of smooth muscles accounting for 5-6% of all soft tissue sarcomas. They are mostly seen in the gastrointestinal tractus, the uterus, and the retroperitoneum. Soft tissue sarcomas comprise <1% of all laryngeal malignancies, most of ...

Linguistic Adaptation, Reliability, Validation, and Responsivity of the Chinese Version of Reflux Symptom Index
Journal of Voice (2016) Vol. 30, No. 1, pp. 104-108

Currently, there is no cost-effective tool available to diagnose laryngopharyngeal reflux (LPR) in the developing country of China. The aim of this study was to achieve a linguistic adaptation of the Chinese version of the Reflux Symptom Index (RSI-CH). A ...

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 Assessment Before, After, and the Day After Opera Performance
Journal of Voice (2016) Vol. 30, No. 2, pp. 186-191

Objective: To explore aerodynamic, acoustic, and laryngeal changes surrounding opera performance. Study Design: Prospective preperformance, postperformance, and day after performance. The laryngeal and vocal function of five male and five female classically trained singers was assessed immediately before, immediately after, ...

Quantification of Vocal Fold Vibration in Various Laryngeal Disorders Using High-Speed Digital Imaging
Journal of Voice (2016) Vol. 30, No. 2, pp. 205-214

Objective: To quantify vibratory characteristics of various laryngeal disorders seen by high-speed digital imaging (HSDI). HSDI was performed on 78 patients with various laryngeal disorders (20 with polyp, 16 with carcinoma, 13 with leukoplakia, 6 with vocal fold nodule, and ...

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 ...

Quantitative Analysis of the Visor-Like Vertical Motion of the Cricoarytenoid Joint in the Living Subject
Journal of Voice (2016) Vol. 30, No. 3, pp. 354-364

The cricoarytenoid joint has a loose capsule and large cavity and may allow the arytenoid distanced from the cricoid cartilage. The objective was to quantify vertical motion of the arytenoid cartilage in the living subject. Axial computed tomography images from ...

Switching of the Laryngeal Cavity From the Respiratory Diverticulum to the Vestibular Recess: A Study Using Serial Sagittal Sections of Human Embryos and Fetuses
Journal of Voice (2016) Vol. 30, No. 3, pp. 263-271

A cecum-like protrusion of the pharynx (the laryngeal cecum or vestibular recess [VR]) develops immediately anterior to the laryngeal part of the respiratory diverticulum. An expansion of the VR has been well described, whereas the fate of the diverticulum is ...
