Vocal Characteristics of Patients With Morbid Obesity.

Introduction: Obesity modifies vocal characteristics, causing abnormal fat deposition in the abdominal region and upper airways. For some authors the voice of the obese is not different from nonobese and the vocal symptoms are scarce; for others dysphonia in obese is reported by 70% of them and the voice becomes hoarse, breathy, and unstable.

Objective: To characterize the voice of patients with morbid obesity.

Laryngeal and vocal alterations after thyroidectomy.

Introduction: Dysphonia is a common symptom after thyroidectomy.

Objective: To analyze the vocal symptoms, auditory-perceptual and acoustic vocal, videolaryngoscopy, the surgical procedures and histopathological findings in patients undergoing thyroidectomy.

Methods: Prospective study.

Are Vocal Alterations Caused by Smoking in Reinke's Edema in Women Entirely Reversible After Microsurgery and Smoking Cessation?

Background: Reinke's edema is a benign lesion of the vocal folds that affects chronic smokers, especially women. The voice becomes hoarse and virilized, and the treatment is microsurgery. However, even after surgery and smoking cessation, many patients remain with a deep and hoarse voice.

Voice Disorders: Etiology and Diagnosis.

Objectives: Voice disorders affect adults and children and have different causes in different age groups. The aim of the study is to present the etiology and diagnosis dysphonia in a large population of patients with this voice disorder.for dysphonia of a large population of dysphonic patients.

Voice Disorders in Teachers: Clinical, Videolaryngoscopical, and Vocal Aspects.

Goal: Dysphonia is more prevalent in teachers than among the general population. The objective of this study was to analyze clinical, vocal, and videolaryngoscopical aspects in dysphonic teachers.

Methods: Ninety dysphonic teachers were inquired about their voice, comorbidities, and work conditions.

Psychogenic dysphonia: diversity of clinical and vocal manifestations in a case series.

Introduction: Psychogenic dysphonia is a functional disorder with variable clinical manifestations.

Objective: To assess the clinical and vocal characteristics of patients with psychogenic dysphonia in a case series.

Methods: The study included 28 adult patients with psychogenic dysphonia, evaluated at a University hospital in the last ten years.

Voice disorders in teachers. A review.

Introduction: Voice disorders are very prevalent among teachers and consequences are serious. Although the literature is extensive, there are differences in the concepts and methodology related to voice problems; most studies are restricted to analyzing the responses of teachers to questionnaires and only a few studies include vocal assessments and videolaryngoscopic examinations to obtain a definitive diagnosis.

Objective: To review demographic studies related to vocal disorders in teachers to analyze the diverse methodologies, the prevalence rates pointed out by the authors, the main risk factors, the most prevalent laryngeal lesions, and the repercussions of dysphonias on professional activities.

Clinical practice: vocal nodules in dysphonic children.

Common among children, vocal symptoms are a cause of concern for parents who seek elucidation of their diagnosis and treatment. Vocal nodules are the major cause of dysphonias in children and are related to vocal abuse. We conducted a literature review considering clinical, physiopathological, epidemiological, and histological aspects of vocal nodules, as well as diagnostic methods, highlighting the main studies addressing this issue.

Laryngeal and voice disorders in patients with gastroesophageal symptoms. Correlation with pH-monitoring.

Purpose: To investigate laryngeal and voice disorders in patients with gastroesophageal symptoms and their correlation with pH-monitoring.

Methods: A prospective study was carried out in patients attended at the Voice Disorder Outpatient Clinics of Botucatu Medical School in a five-year period and had vocal and gastroesophagic symptoms. Patients underwent videolaryngoscopy, auditory-perceptual vocal analyses, computerized acoustic vocal analysis and dual probe pH-monitoring for 24 hours.

Dysphonia in children.

Introduction: Vocal symptoms are common among the pediatric population and are often caused by vocal abuse. Laryngoscopy is essential for their diagnosis because it helps differentiate several laryngeal lesions, leading to a decision for suitable treatments considering each case.

Objectives: This study aims to present the clinical characteristics, and the laryngoscopic diagnosis of a dysphonic child population.

Maximum phonation time and s/z ratio in a large child cohort.

Aim: The purpose of this study was to provide normal values for maximum phonation time (MPT) and the s/z ratio by examining 1660 children aged 4-12 years and without vocal signs or symptoms.

Methods: The technique was based on the sustained emission of the /a/ vowel and fricatives /s/ and /z/.

Results: The average of the MPT in children of the different age groups was as follows: 6.

Epidemiological study of dysphonia in 4-12 year-old children.

Unlabelled: Children dysphonia studies have reported an incidence of 4.4 to 30.3%.

Consequences of chronic nasal obstruction on the laryngeal mucosa and voice quality of 4- to 12-year-old children.

Introduction: Dysphonia affects 6% to 23% of children, and chronic nasal obstruction may participate in its pathophysiology.

Objectives: To study the effects of chronic nasal obstruction on children's vocal quality.

Subjects And Methods: Two study groups were formed: nasal obstruction group (NOG), consisting of 60 children aged 4-12 years with important symptoms of chronic nasal obstruction; and a control group (CG), similar in gender and age range, consisting of healthy students without nasal, vocal, or auditory symptoms.

Mucosal bridge of the vocal fold: difficulties in the diagnosis and treatment.

Summary: Mucosal bridges are rare laryngeal lesions probably of genetic origin. They may cause dysphonia of varying degrees, especially when associated with other laryngeal lesions such as vocal sulci and cysts. Reports on mucosal bridges are rare, and the better treatment is inconclusive.

Normative study of vocal acoustic parameters from children from 4 to 12 years of age without vocal symptoms: a pilot study.
