INTRODUCTION: Unilateral vocal fold paresis may significantly impair the vocal quality and laryngeal competence of a child. Relatively little literature relates to injection medialisation laryngoplasty (IML) in children and previous reports have involved small numbers of heterogenous cases. METHODS: A retrospective review was conducted of paediatric patients managed by our multidisciplinary specialist voice clinic undergoing IML for unilateral vocal fold paresis...

OBJECTIVE: Flexible nasolaryngoscopy (FNL) is considered the gold standard for evaluation of vocal fold mobility but there has been no data on the reliability of interpretation in the infant population. Visualization may be limited by excessive movement, secretions, or floppy supraglottic structures that prevent accurate diagnosis of vocal fold movement impairment (VFMI). We sought to evaluate the inter- and intra-rater reliability of FNL for the evaluation of VFMI in young infants. STUDY TYPE: Case-control...

In this study, we have reproduced the cough clearance process with an Eulerian wall film model. The simulated domain is based on realistic geometry from the literature, which has been improved by adding the glottis and epiglottis. The vocal fold movement has been included due to the dynamic mesh method, considering different abduction and adduction angles and velocities. The proposed methodology captures the deformation of the flexible tissue, considers non-Newtonian properties for the mucus, and enables us to reproduce a single cough or a cough epoch...

Lewis-Sumner syndrome (LSS) is a rare disease characterized by asymmetrical and multifocal mononeuropathy commonly located in the upper limbs. Some rare cases affecting cranial nerve have been described, but LSS is unknown to affect especially laryngeal nerves. This paper presents the first case of unilateral vocal fold paresis caused by an LSS in a 59-year-old man complaining of dysphonia, breathy voice, and vocal fatigue. Epidemiology, clinical features, diagnosis, and treatment will be described.

The voice of persons with Williams syndrome (WS) is described as hoarse with a deep and unstable fundamental frequency (f0). These observations may be justified by the deficit of elastin due to a haplo-insufficiency in the ELN gene characteristic of the syndrome. In view of the possible relationship between elastin deficit and dysphonia, a study of the dynamic function of WS phonation was conducted by means of biomechanical analysis. In order to assess the presence of dysphonic symptoms and their degree of severity, the biomechanical description of WS phonation has been evaluated in terms of dynamic mass and viscoelasticity estimates...

OBJECTIVE: A vibratory vocal fold replacement would introduce a new treatment paradigm for structural vocal fold diseases such as scarring and lamina propria loss. This work implants a tissue-engineered replacement for vocal fold lamina propria and epithelium in rabbits and compares histology and function to injured controls and orthotopic transplants. Hypotheses were that the cell-based implant would engraft and control the wound response, reducing fibrosis and restoring vibration. STUDY DESIGN: Translational research...

A method of fabricating electrically conductive synthetic vocal fold replicas and monitoring their vibration via resistance measurement is presented. Normally non-conductive silicone replicas were coated with conductive graphite and subjected to long-term vibration tests. Synchronized resistance and imaging data using hemilarynx and full larynx configurations showed an inverse correlation between replica contact area and resistance during vibration, similar to clinical electroglottography (EGG) used to estimate vocal fold contact area...

Laryngopharyngeal reflux (LPR) may contribute to the development of laryngeal diseases including vocal fold leukoplakia. Clinical methods of determining LPR are limited. Pepsin, as an exogenous protein, is considered as a biomarker of LPR. The aim of the current study was, therefore, to detect pepsin by immunohistochemistry in the biopsies from patients with vocal fold leukoplakia, and by which, to determine the potential association of LPR and vocal leukoplakia. A total of 26 biopsies from patients with vocal fold leukoplakia were examined in comparison with 20 vocal fold biopsies from control subjects...

INTRODUCTION: Glottic leakage during phonation is a direct consequence of unilateral vocal fold (VF) paralysis. This air leakage can be in the horizontal plane and in the vertical plane. Presently, there is no easily applicable medical device allowing noninvasive, office-based measurement of the relative vertical position of the VFs. The larynx ruler (LR) is a laser-based measuring device that could meet the previously stated need, using a flexible endoscope. This study represents a proof of concept regarding the use of the LR in assessing VF relative positions in the vertical plane...

OBJECTIVES: The Acoustic Voice Quality Index (AVQI) and the Cepstral Spectral Index of Dysphonia (CSID) are two multiparameter acoustic indices designed to objectively estimate dysphonia severity and track treatment outcomes. This study compared the performance of these two indices using a common corpus of dysphonic speakers. METHOD: Pre- and posttreatment samples of sustained vowel and connected speech were elicited from 112 patients across six diagnostic categories: unilateral vocal fold paralysis (n = 12), adductor spasmodic dysphonia (n = 12), primary muscle tension dysphonia (n = 12), benign vocal fold lesions (n = 12), presbylaryngis (n = 12), and mutational falsetto (n = 12)...

Importance: Compromised cough effectiveness is correlated with dysphagia and aspiration. Glottic insufficiency likely yields decreased cough strength and effectiveness. Although vocal fold augmentation favorably affects voice and likely improves cough strength, few data exist to support this hypothesis. Objective: To assess whether vocal fold augmentation improves peak airflow measurements during maximal-effort cough following augmentation. Setting, Design, Participants: This case series study was conducted in a tertiary, academic laryngology clinic...
