Do Flexible Silicone Tubes Immersed in Water Combined With Vocalise Improve the Immediate Effect on Voice?

Purpose: This study aimed to analyze the immediate effect on a singer's voice of a flexible silicone tube immersed in water combined with ascending and descending vocalise scales compared with ascending and descending vocalise scales alone.

Method: A pre- and post-intervention quasi-experimental study was conducted. Thirty adult singers between 18 and 45 years old with no laryngeal disorders performed the two techniques for 3 min each on different days.

Surgical interventions for pediatric unilateral vocal fold paralysis: A systematic review and meta-analysis.

Objective: To evaluate outcomes of injection laryngoplasty (IL) and laryngeal reinnervation for the treatment of pediatric Unilateral Vocal Fold Paralysis (UVFP), especially on swallowing and quality of voice.

Methods: A literature review was performed in Medline/PubMed and Cochrane Library, following PRISMA guidelines, with no constraints on publication date. We included studies in English, Portuguese or Spanish about surgical treatment for UVFP on the pediatric population (0-21 years) that documented outcomes for one of the following techniques: IL or laryngeal reinnervation.

Effect of Resonance Tube Technique on Oropharyngeal Geometry and Voice in Individuals with Parkinson's Disease.

Objective: To verify the immediate effect of the flexible resonance tube vocal technique on the oropharyngeal geometry and vocal acoustic parameters of individuals with Parkinson's disease (PD) and to study the correlation between oropharyngeal geometry and the intensity and fundamental frequency (f0) parameters of the voice.

Methods: Forty individuals participated-20 with PD and 20 healthy individuals, with a mean age of 60.95 (± 5.

Effect of sugarcane biopolymer in vocal fold of rabbits. Comparative study with calcium hydroxyapatite.

Purpose: To compare the inflammatory reaction caused by the injection of a sugarcane biopolymer (SCB) into the vocal fold of rabbits with that caused by calcium hydroxyapatite (CaH).

Methods: CaH (Radiesse(r)) and SCB gel were injected respectively into the right and left vocal cords of thirty rabbits. The rabbits were distributed into two equal groups and sacrificed at three and twelve weeks after injection.

Effect of sugarcane biopolymer gel injected in rabbit vocal fold.

Introduction: Alterations in the vocal folds that involve volume reduction and glottal closure failure result in exaggerated air escape during speech. For such situations, the use of implants or grafts of different materials has been proposed.

Objective: To define the effect of sugarcane biopolymer gel when implanted in the vocal folds of rabbits.

New system of instrument stabilization in laryngeal microsurgery.

Unlabelled: Laryngeal microsurgery is a kind of treatment for various laryngeal diseases. Because of the need of long instruments and delicate maneuvers, involuntary movements represent relevant difficulty and may be responsible for unintended post-operative results.

Aim: This study proposes a new stabilization system, flexible and versatile, which can significantly reduce involuntary movements made by surgeons.
