Vocal fold abduction/adduction posturing is key to phonation control. As biomechanical models of the larynx increase in complexity, there is a need to verify them with laboratory data. To help experimental cross-validation of models, ranges of vocal process displacement were reviewed and combined. Although general inter-study agreement was found, there was substantial variation. Using a model of vocal fold posturing, insights were uncovered that could not otherwise be made; best-practice guidelines and research avenues for future studies of vocal posturing were also outlined.

Objective: Two-jaw surgery corrects jaw deformities by adjusting occlusion and reshaping the jaw. This technique carries a high risk of pharyngolaryngeal injury due to frequent head and neck movements during intraoperative maneuvers and prolonged intubation, although the details remain unclear. This study explored the frequency and causes of postoperative pharyngeal complications following maxillary translocation.

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.

Background: Vocal fold leukoplakia (VFL), a precancerous lesion of the larynx, is characterized by white plaques on the vocal fold mucous membrane. Currently, there are no reliable biomarkers to predict the recurrence and malignant transformation of VFL. Considering chondroitin sulfate proteoglycan 4 (CSPG4) as a biomarker for malignant tumors such as laryngeal squamous cell carcinoma (LSCC), we conducted this cohort study to evaluate the prognostic influence of CSPG4 expression on VFL patients.

: This study aimed to determine the positive predictive value of our NMD Suspicion Criteria in the diagnosis of NMDs. Other clinical factors routinely examined in our voice and swallowing examinations were also investigated to see if they had a significant association with the diagnosis of NMDs. : This study retrospectively investigated the medical charts of patients who visited our Voice and Swallowing outpatient clinic between 2013 and 2022.

: Arytenoid dislocation (AD) and subluxation (AS) impact vocal fold mobility, potentially affecting the quality of life. Their management, including the timing and modality of treatment, remains a subject of research. Our primary objective was to assess and compare the available treatment strategies for AS and AD.
