Maximum Phonation Time and Body Mass Index in Nondysphonic Eutrophic Children.

Background: Literature presents controversial maximum phonation time values in children.

Objective: Verify and correlate the maximum phonation time of vowels /a, i, u/ and the body mass index of children.

Method: Evaluation of 484 children, eutrophic and without dysphonia, aged from 4:00 to 7:11 years.

Glottal Closure in Women with No Voice Complaints or Laryngeal Disorders.

 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.  The aim of the present study was to verify the association between glottic closure, acoustic parameters, and some characteristics of the videolaryngostroboscopy of young women without vocal complaints nor laryngeal disorders.  This is a cross-sectional study with 56 women between 20 and 30 years old who underwent videolaryngostroboscopy.

Auditory-Perceptual Characteristics of the Voice of Nondysphonic School Children From 8:0 to 10:0 Years Old.

Objective: Describe and correlate the auditory-perceptual characteristics of the voice of nondysphonic school children from private and public schools from 8:0 to 10:0 years old, female and male.

Methods: Cross-sectional, quantitative and retrospective study of students from schools in a small city. Auditory-perceptual evaluations of 154 nondysphonic students were analyzed.

Acoustic vocal measures in women without voice complaints and with normal larynxes.

Unlabelled: It is important to establish normal voice standards in order to help guide voice professionals.

Aim: to describe acoustic voice measures of adult young women with normal larynxes and without voice complaints.

Method: 56 women underwent ENT evaluation and speech screening.

Reverse phonation--physiologic and clinical aspects of this speech voice therapy modality.

Unlabelled: Reverse phonation is the voice production during inspiration, accomplished spontaneously in situations such as when a person sighs.

Aim: to do a literature review, describing discoveries related to the use of the reverse phonation in the clinical practice, the anatomy and physiology of its production and its effects in vocal treatments; and moreover, indications and problems of the technique for speech disorders treatment and voice enhancement.

Results: there were reports of significant changes in vocal treatment during with the use of reverse phonation: ventricular distention, ventricular folds separation, increase in the fundamental frequency, mucous wave inverse movement; and it also facilitates the dynamic study of the larynx when associated with endoscopy, making it possible to have a better definition of lesion localization in vocal folds superficial lamina propria layers.
