The present work proposes automatic methods for determining the extent of dysphonia in patients with spasmodic dysphonia. Spasmodic dysphonia is a disorder of the larynx which involves involuntary contractions of the vocal folds during speech production. Numerous acoustical aspects of a voiced spasmodic speech signal which indicate the presence of these vocal spasms have been identified, includ...

Injury to the recurrent laryngeal nerve (RLN) is a potentially debilitating complication of anterior cervical discectomy and fusion (ACDF) surgery, which can lead dysphonia, dysphagia, aspiration. Intraoperative adductor reflex (LAR) monitoring newly developed technique assess monitor RLN integrity. However, role LAR in ACDF surgery poorly studied. Here, we describe case intraoperative was succ...

Adductor spasmodic dysphonia is the most common form of laryngeal dystonia and comprises about 80% of all laryngeal dystonias. It is characterized by strained and strangled voice quality causing significant impairment to the patient. This article focuses on the surgical treatment of adductor spasmodic dysphonia by thyroarytenoid muscle ablation. It provides longlasting control of symptoms and p...

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. Assessed variables included gender, age, occupa...

Since several years, many studies have focused on the objective measurement-analysis for dysphonic voice assessment, proposed as an alternative to the perceptual evaluation [5] that is extensively used by clinicians. In most cases, these studies describe classification systems, based on acoustic, physiological and/or aerodynamic parameters, in order to improve the performance and to help clinic...

UNLABELLED The modern theory of hoarseness is that there are multifactorial etiologies contributing to the voice problem. The hypothesis of this study is that muscle tension dysphonia is multifactorial with various contributing etiologies. METHODS This project is a retrospective chart review of all patients seen in the Voice Speech and Language Service and Swallowing Center at our institution...

Resolution of psychogenic dysphonia is often quick and effortless for client and therapist alike. In such instances, the therapeutic interventions are simple and straightforward, insights are reached without difficulty, and once normal voice has been established, resumption of dysphonia or other psychosomatic symptoms rarely occurs. Sometimes, however, psychogenic dysphonia is extremely difficu...

Adductory spasmodic dysphonia is a focal dystonia of laryngeal muscles. Patients with this disorder typically have severe vocal difficulties, with significant functional, social, and emotional consequences. There is no widely accepted cure for this condition, however, botulinum toxin injections of the thyroarytenoid muscles are considered by most voice clinicians to be the state of the art trea...

The use of speech recognition systems as a replacement for other types of transcription systems is increasing rapidly, partly because many people are unable to use conventional keyboards as a result of upper-extremity repetitive strain injury (RSI). However, the frequent or continuous use of such systems can cause muscle tension dysphonia in some patients. The scientific literature suggests tha...
