Background: Benign vocal fold lesions (BVFLs) are usually caused by abuse or misuse. Conservative treatment and micro laryngeal surgery (MLS) recommended in the treatment. However, conservative measures difficult to perform some patients contraindicated for general anesthesia.Objective: This study is designed assess practical application, effectiveness, side effects of office-based steriod inje...

Intoduction: Dysphonia is the main symptom of lesions that affect the larynx. Many of those require surgical treatment. Vocal cord lesions are the most common and the most prevalent indication for laryngeal microsurgery. Aim: To conduct a study of laryngeal lesions and their management by microlaryngoscopy. Materials and methods:The main objective being to highlight the importance of microlaryn...

INTRODUCTION We present a patient with a novel finding of bilateral mucosal bridges, bilateral type III trans-vocal fold sulci vocales, and a vocal fold polyp. Although sulci and mucosal bridges occur in the vocal folds, it is rare to find multiples of these lesions in a single patient, and it is even more uncommon when they occur in conjunction with a vocal fold polyp. To our knowledge, this i...

introduction:dystonia is a disorder of movement caused by various etiologies. laryngeal dystonia is caused by the spasm of laryngeal muscles. it is a disorder caused by vocal fold movement in which excessive adduction or abduction of the vocal folds occurs during speech. the pathophysiology of this type of dystonia is not fully known. some researchers have suggested that basal ganglia structure...

In this study, we investigate physical parameters which can be used to classify speech as either stressed or neutral based on a two-mass vocal fold model. The model attempts to characterize the behavior of the vocal folds and fluid airflow properties when stress is present. The two-mass model is fitted to real speech to estimate the values of physical parameters that represent the stiffness of ...

OBJECTIVE The aim of this study is to evaluate the correlations among the basic video laryngostroboscopic (VLS) parameters and vocal function assessed using a multidimensional set of perceptive, acoustic, aerodynamic, and subjective measurements. METHODS Digital VLS recordings and multidimensional voice assessment were performed for 108 individuals, namely 26 healthy and 82 patients with mass...

We discuss a novel low-order massspring model of human vocal folds with incompressible 1D flow. Our model consists of three subsystems: a flow model, a nonsymmetric mass-spring model for the vocal folds, and a resonator representing the vocal tract (VT).

OBJECTIVES/HYPOTHESIS This study was designed to assess the feasibility of the submucosal infusion technique combined with microflap dissection as a radical therapeutic and diagnostic option for precancerous laryngeal leukoplakia. STUDY DESIGN Retrospective study. METHODS Severe dysplasia or carcinoma in situ was diagnosed after phonomicrosurgical dissections in 25 patients with unilateral ...
