The correlation between laryngo-pharyngeal reflux and dysphonia has been evaluated in patients without significant laryngoscopic findings and without vocal misuse. Studies were performed, using a validated questionnaire on typical reflux symptoms as well as instrumental means, e.g. videolaryngoscopy, multi-electrode 24-hr oesophageal pH monitoring, vocal acoustic analysis, gastro-oesophagoscopy...

An Australian family group is described where at least twenty members have inherited torsion dystonia and two siblings with an affected mother have similar clinical manifestations, but have also the biochemical and pathological changes found in Wilson's disease. Whispering dysphonia was the commonest presenting symptom, and a diagnosis of hysteria was invariably made if the family history was n...

Purpose: Wearing face masks during the COVID-19 pandemic has become a very important hygiene measure to block or prevent respiratory droplets and infections. The purpose of this study is explore effect wearing on acoustical measurement voice speech in patients with hyperfunctional disorders, present guidelines for mask when evaluating speech.Methods: A total 20 disorders who diagnosed vocal nod...

Benign laryngeal disorders result in dysphonia because of effects on glottic closure and the vibratory characteristics of the true vocal fold. Treatment is initially directed at reversing medical conditions and patterns of abuse with surgery reserved for unresolving lesions resulting in troublesome dysphonia. Benign lesions that require surgery are excised as precisely as possible sparing overl...

Description and quantification of the symptoms of adductor spasmodic dysphonia often reflect the clinician's knowledge of the disorder, ideas about the cause of the disorder, and personal experience. No reliable instrument that identifies and quantifies the spectrum of perceptual symptoms has been available. Therefore, we developed a standardized measure called the Unified Spasmodic Dysphonia R...

Concerned with pathological voice assessment, this paper aims at characterizing dysphonia in the frequency domain for a better understanding of related phenomena while most of the studies have focused only on improving classification systems for diagnosis help purposes. Based on a first study which demonstrates that the low frequencies ([0-3000]Hz) are more relevant for dysphonia discrimination...

introduction: laryngopharyngeal reflux (lpr) is considered an important cause of voice disorder. we aimed to determine the frequency of lpr in patients with voice disorder and the association between koufman reflux symptom index (rsi), reflux finding score (rfs), gastroesophageal reflux disease (gerd), and proximal acid reflux in these patients. materials and methods: we performed a prospective...

PURPOSE To establish the occurrence of dysphonic children and to relate data from auditory-perceptive, acoustic and vocal self-perception analyses of dysphonic and non-dysphonic children. METHODS Participants were 70 children, 37 female and 33 male, with ages ranging from 6 to 10 years. The sustained emission of the vowel /a/ was recorded, and children replied to the question "What do you thi...

the objective of this work is the estimation of vocal tremor in patients with spasmodic dysphonia before and after treatment, and the comparison of their tremor characteristics with those estimated from healthy speakers. as an outcome, a new tremor attribute is introduced, the deviation of the modulation level and a novel method is proposed for classifying speakers according to the prevalence o...
