Active clinical trials for "Dysphonia"

This study aims to study the effectiveness of preoperatively nebulized dexamethasone in reducing the incidence and severity of Post Operative Sore Throat, POST in patients undergoing surgery under general anesthesia using the Ambu® AuraGainTM SGA device, with secondary aims of determining the effectiveness of dexamethasone in reducing post-operative cough severity and hoarseness of voice

This is a randomized controlled trial focusing on the effect of different tracheal tube cuff shape; the tapered-shaped tracheal tube cuff versus the cylindrical-shaped tracheal cuff in anterior cervical spine surgery.

The purpose of this study is an evaluation of the effect of the reinforced endotracheal tube on post-operative hoarseness and sore throat undergoing thyroidectomy

For many years, it is known that asthmatics have more often dysphonia. However, no study has so far analyzed the reality of dysphonia in asthmatic by making phoniatric tests. The etiology of dysphonia in asthmatic remains controversial. Indeed, for a long time, inhaled corticosteroids have been considered as responsible for organic abnormalities of the vocal cords. We hypothesized that women with asthma have more often dysphonia, and that dysphonia is rather functional origin.

Focal dystonia is a neurological movement disorder characterized by excessive involuntary muscle contractions of any body part. Spasmodic dysphonia (SD) is a type of focal dystonia characterized by excessive contraction of intrinsic muscles in the larynx, leading to difficulty in speaking and affecting effective communication. The cause of SD is unknown and there are no treatments that produce long-term benefits. Previous studies have suggested that SD and other focal dystonias are associated with decreased inhibition in sensorimotor areas in the brain. However, no studies have investigated the effects of modulating excitability of the laryngeal motor cortex in healthy individuals or SD. The goal of this pilot project is to determine if brain excitability of the laryngeal motor cortex can be changed with low-frequency inhibitory repetitive transcranial magnetic stimulation (rTMS) in individuals with SD and healthy controls. Considering that rTMS at low frequencies (≤1 Hz) produces lasting inhibition in the brain, and that SD is associated with decreased cortical inhibition, the purpose of this pilot study is to determine safety, feasibility and response to 1Hz rTMS to the laryngeal motor cortex in individuals with SD and healthy people. The results will help understand changes associated with the disorder, as well as contribute to the development of future clinical interventions for SD.

The purpose of this study is to assess the effect of voice exercise and voice rest on subject's perception of vocal handicap and communicative participation following Botox injections for adductor spasmodic dysphonia.

The purposes of the proposed study are: a) to determine whether Flow Phonation can decrease Laryngeal Resistance (Rlaw) in patients with Muscle Tension Dysphonia (MTD); and b)establish the relationship between changes in measures of Rlaw and phonatory airflow to endoscopic, perceptual, acoustic, and handicap assessment ratings. MTD can have a debilitating effect on individuals who rely on their voices the most-teachers, preachers,salespeople, singers-costing them time, money, and even their jobs. It can lead to vocal fatigue, pain, and complete loss of voice. While treatments have emerged with some promising effects, no treatments have proven to have long-term benefits to all patients. Our preliminary data demonstrate Flow Phonation training resulted in significant decreases in Laryngeal Resistance to phonatory airflow with associated improvements in voice quality and voice handicap ratings. Sample size for our pilot study was small; no control group was utilized; and outcome measures were limited. In the proposed investigation, a larger sample will be obtained, a control group of participants receiving only Vocal Hygiene Training will be used for comparison during the first 3 weeks, and a wider range of outcome measures will be included over a longer period of time (1 year).

The Neurogenic Dysphonia/Dysphagia Registry is designed to be purely observational (i.e. non-interventional, exploratory). Patient data collected from the registry is expected to be consistent with any information which can be obtained during usual care of patients with dysphonia/dysphagia treated with vocal fold augmentation.

This study will compare the effects of vocal rest versus continuous vocalization for one hour immediately following botulinum toxin injections for adductor spasmodic dysphonia.

The overall aim of the project is to develop a new method for treatment of untreatable severe hoarseness due to vocal fold scarring by local injection of autologous mesenchymal stromal cells (MSC). At present there is no lasting effective treatment for this condition which results in personal suffering, and often extended sick leave, change of work or unemployement for the patients. Based on the previous results the investigators expect the autologous MSC product KI-MSC-PL-204 to be a new effective treatment without side effects for many patients with severe hoarseness or aphonia due to vocal fold scarring.
