1. Learning curve for endoscopic evaluation of vocal folds lesions with narrow band imaging
Resumo Introdução: Os métodos endoscópicos estão progredindo e se tornando comuns no diagnóstico clínico de rotina também na otorrinolaringologia. Um número relativamente grande de pesquisas demonstrou alta precisão na endoscopia com imagem de banda estreita na diferenciação de lesões benignas e malignas nas pregas vocais. Entretanto, pouco se

2. Glottal Closure inWomen with No Voice Complaints or Laryngeal Disorders
Abstract Introduction The understanding of normal vocal production is essential to guide any voice professional as it is fundamental to understand the effects of the posterior glottal gap on the vocal quality. Objective The aim of the present study was to verify the association between glottic closure, acoustic parameters, and some characteristics of the

3. The Effect of Fibroblast Growth Factors in Grafted Fascia into the Vocal Fold of Rabbits
Abstract Introduction The human larynx is a very important organ for communication. Many conditions lead to scarring of the vocal folds, decreasing voice quality. Objective We aimed to determine whether fibroblast growth factors (FGFs) may influence tissue integration of grafted fascia into the vocal folds of an animal model. Methods This is an experim

4. Laryngeal and vocal alterations after thyroidectomy
Resumo Introdução: A disfonia é um sintoma comum após a tireoidectomia. Objetivo: Analisar os sintomas vocais, auditivo-perceptivos e acústica vocal, videolaringoscopia, procedimento cirúrgico e achados histopatológicos em pacientes submetidos à tireoidectomia. Método: Estudo prospectivo. Pacientes submetidos à tireoidectomia foram avaliados da

5. Effect of Vocal Fry on Voice and on Velopharyngeal Sphincter
Abstract Introduction It is known that the basal sound promotes shortening and adduction of the vocal folds and leaves the mucosa looser. However there are few studies that address the supralaryngeal physiological findings obtained using the technique. Objective To check the effectiveness of using vocal fry on the voice and velopharingeal port closure of

6. Ortner's Syndrome: Secondary Laryngeal Paralysis Caused by a Great Thoracic Aorta Aneurysm
Introduction Recurrent laryngeal nerve injury caused by cardiovascular disease is a rare condition, and often it is the only prominent sign of an imminent break of an aortic artery aneurysm.
Objective To report left laryngeal paralysis caused by a great aortic arch aneurysm and to highlight the importanc

7. Premalignant Laryngeal Lesions: Twenty-Year Experience in Specialized Service
Introduction Premalignant lesions are considered both a hyperplastic and dysplastic stage of epithelial lesions in the glottic larynx that may or may not progress into an invasive carcinoma. The evolution of laryngoscopic procedures in outpatients has provided better access to important information for safe and easy diagnosis of laryngeal pathologies. Obj

8. High-speed kymography identifies the immediate effects of voiced vibration in healthy vocal folds
INTRODUCTION: The effects of voiced vibration technique can be assessed by laryngeal imaging. Kymographic images derived from high-speed videoendoscopy allow actual visualization of vocal folds vibration. PURPOSE: The aim of this study is to identify the immediate effects of the voiced vibration technique in healthy vocal folds using high-speed digital laryn

9. Extração e avaliação da dinâmica não-linear da voz utilizando vídeo de alta velocidade da laringe / Extraction and evaluation of vocal folds dynamics using high-speed laryngeal imaging
No contexto da fonação, as pregas vocais são responsáveis pela produção primária do sinal de voz na laringe. Tão importantes quanto complexas, elas exibem uma dinâmica rica e uma série de comportamentos que determinam as características fundamentais do sinal emitido pela boca. Com o intuito de avaliar suas propriedades sob a luz dos métodos da di

10. Avaliação dos efeitos de exercícios vocais em vozes normais com análise perceptivo-auditiva, acústica e de imagens laríngeas obtidas por videolaringoscopia de alta velocidade / Immediate effects of vocal exercise in normal voices using perceptual, acoustic analysis and of the high-speed videolaryngoscopy images
The aim is to detect the immediate effect of vocal exercises in normal voices. Thirty healthy subjects from 19 to 45 year old with no vocal complains participated in the study. The sustained vowels /a/ and /E/ were recorded in two moments: the first, we recorded the habitual voice, before any exercises; and the second, after from 1 to 5 minutes of continuous

11. Análise do padrão vibratório das pregas vocais em sujeitos com e sem nódulo vocal por meio de videolaringoscopia de alta velocidade / Analysis of the vibrations of vocal folds in subjects with and without vocal nodule by means of High-speed videoendoscopy
O objetivo do presente trabalho foi analisar por meio da videolaringoscopia de alta velocidade o padrão vibratório das pregas vocais de indivíduos com e sem nódulo de prega vocal. Além disso, comparar o padrão vibratório das pregas vocais, de todos os grupos, analisado pela videolaringoscopia de alta velocidade com os resultados das análises acústic

12. O rei Sebastião que era muito resmungão
PURPOSE: one major cause of dysphonia can be linked to the presence of vocal folds nodules - a condition commonly seen in children due to vocal misuse and/or vocal abuse. The present health education project, also directed to parents and educators, aims at making children (the project's chief target-population) aware of how to make a correct use of their voi
