The purpose of this paper is to examine the change of laryngeal vibratory mechanism in 10 males and 9 females trained and untrained singers. The electroglottographic (E.G.G.) data analysis demonstrated strong evidence to support the view that such event could be considered as a whole physiological entity. In fact findings clearly indicated biomechanical, neuromuscular and central levels in the control of the laryngeal vibration involved in the change of mechanism.

Subglottic stenosis (SGS) presents a rare, yet challenging condition characterized by airway obstruction below the glottis, with diverse etiologies ranging from congenital to acquired factors like intubation or autoimmune diseases. Diagnosis and management of SGS during pregnancy are particularly complex due to limited literature and diagnostic consensus. This article presents a case of a 26-year-old pregnant woman presenting with escalating dyspnea and stridor attributed to SGS, most likely secondary to idiopathic etiology.

Patients with nasogastric (NG) tubes require careful monitoring due to the potential impact of the tube on their ability to swallow safely. This study aimed to investigate the utility of high-resolution cervical auscultation (HRCA) signals in assessing swallowing functionality of patients using feeding tubes. HRCA, capturing swallowing vibratory and acoustic signals, has been explored as a surrogate for videofluoroscopy image analysis in previous research.

Objective: This study aims to evaluate the clinical outcomes of patients receiving in-office vocal fold steroid injections (VFSI), highlighting relatively new measures around vocal pitch.
Methods: Patients with a diagnosis of vocal fold scar who received in-office VFSI from 2013 to 2024 were evaluated. Pre- and post-steroid Voice Handicap Index (VHI-10) scores, stroboscopic vibratory parameters, acoustic measures of cepstral peak prominence (CPP), and fundamental frequency coefficient of variation (F0CoV) during sustained phonation were analyzed using Wilcoxon signed-rank tests and McNemar's tests.
