Filter by:Post-operative scarring on vocal cords is responsible for disorders of the vibration of the lining to the original dysphonia can be troublesome for the patient both in his private and professional life. There is no currently codified treatment for this type of situation and no therapeutic antifibrotic has been effective. Cell therapy is a promising new approach.After a liposuction and removing of mature adipocytes (40 to 60%), the remaining cells called stromal vascular fraction (SVF) could be isolated. SVF consists of a heterogeneous cell population including multipotent stem cells similar to mesenchymal stem cells present in bone marrow. The investigators hypothesis is that the trophic and antifibrotic properties of SVF could benefit patients with vocal cords scarring responsible for dysphonia.
Laryngeal Dystonia (LD), also commonly referred to as spasmodic dysphonia, is a neurological voice disorder characterized by involuntary dystonic contractions of the laryngeal muscles. Current treatments such as botox and voice therapy only provide temporary relief and thus, the investigators are exploring new strategies to provide long-term, sustained improvement. Deep Brain Stimulation (DBS) is a neurosurgical procedure that involves the implantation of electrodes to deliver electrical stimuli to specific brain regions. It is the standard surgical treatment for many other movement disorders such as Parkinson's disease, essential tremor, and primary dystonia. This trial has been designed to test the hypothesis that DBS can improve the vocal dysfunction of LD.
For adductor spasmodic dysphonia, there is a need for establishing a new therapy under the present circumstance where no standard therapy has been established yet and existing therapies fail to provide permanent effect. Evaluation of the efficacy of type 2 thyroplasty using titanium bridges will expand the therapeutic options available for adductor spasmodic dysphonia and establishment of a standard therapy.
The purpose of this study is to evaluate the effectiveness and safety of the Comprehensive Voice Rehabilitation Program compared with Vocal Function Exercises in behavioral dysphonia.
Despite the considerable use of oral steroids in the regular management of benign vocal fold lesions there is little evidence base in the literature. This study will investigate the efficacy of oral steroids for the treatment of vocal fold lesions in a controlled manner. The specific aim of this study is to determine the effectiveness of of a short course of oral steroids prior to behavioral voice therapy in patients with benign, phonotraumatic vocal fold lesions. Enrolled subjects will be randomized using a random numbers table to either receive oral steroids or no steroids prior to the initiation of voice therapy. The therapist and individuals involved in the collection and analysis of data will be blinded as to whether the subject received drug. Prior to initiation of therapy subjects will be asked to return for an interval evaluation during which they undergo videostroboscopy and voice evaluation. Subjects will enter then the voice therapy phase . After an initial evaluation to determine the best mode of therapy they will receive a behavioral voice therapy course, which includes a range of behavioral modifications and motor learning techniques, along with lifestyle measures. In all these phases acoustic and aerodynamic measurements will be collected as well as audio-visual material from the videostroboscopic exams. The investigators hypothesize that oral steroids will lead to a reduction in lesion size, which will substantially aid in the delivery and incorporation of voice therapy techniques, contributing to the improvement of overall laryngeal biomechanics and providing an ideal starting point for behavioral voice therapy.
This pilot trial studies pulsed dye laser in treating patients with post radiation dysphonia. Dysphonia, or vocal cord scarring, can include trouble with the voice when trying to talk, such as hoarseness, change in voice pitch, and poor voice quality, and it commonly happens after radiation therapy for laryngeal cancer. Pulsed dye laser may improve post radiation dysphonia.
The objectives of this study are to assess the safety of azficel-T treatment for dysphonia related to vocal fold function and to evaluate the efficacy of azficel-T for the treatment of dysphonia related to vocal fold function.
ABSTRACT: The aim of this study was to investigate the effect of betamethasone gel and lidocaine jelly (over tracheal tube cuff) compared with distilled water on the post intubation syndrome incidence. This study has not been carried out in Iran. 99 patients of either sex undergoing elective surgery were recruited in a single blind randomized study. The patients, using randomization table, were divided into three groups. Anesthetics and medications used during surgery were similar for all the patients. For the all patients, the incidence of postoperative sore throat, cough and hoarseness of the voice in the different follow-up periods (1, 6 and 24 hours) based on the different types of medications were obtained.
The purpose of this study is to carry out a high-level treatment efficacy study on children with speech sound disorders with motor speech involvement (SSD-MSI) using a well-controlled Randomized Controlled Trial design. The intervention of choice is the Prompts for Restructuring Oral Muscular Phonetic Targets (PROMPT) approach, which has been effective in treating motor speech disorders in adults and in children with autism and cerebral palsy.
Muscle tension dysphonia (MTD) is a disabling voice disorder which causes severe voice change, neck pain, and voice fatigue. Current therapy modalities to treat these disorders include multiple visits to a qualified speech language pathologist (SLP) for rehabilitation with voice exercises and focused laryngeal/neck massage. Access to these services is difficult with long waitlists and often not covered by current public health insurance or locally available to many patients in Ontario. The goal of this study is to demonstrate a reduction in symptoms and improvement in vocal function by applying an external vibration device to key sites (e.g. jaw, neck, skull base) commonly identified as a source of abnormal muscle tension and injury in certain voice disorders, specifically MTD. This study will also investigate the effect of external vibration on the voice quality in classically trained singers (CTSs). Certain desirable acoustic qualities in a singers' voice are only accessible when the larynx and its extrinsic muscles are in a relaxed state. Muscle misuse and vocal strain are common problems in performers, which can result in conditions that require surgery and speech therapy, and may lead to a loss of income. Similar to vocal warm up exercises which contribute to the prevention of vocal injury, external vibration is expected to improve muscle perfusion in an acute setting and may have a direct effect on vocal fold cover viscosity. Both study groups will be randomized to receive either the external vibration device or a sham device. The sham device looks identical to the experimental device but has the vibration component removed.
