Active clinical trials for "Dysphonia"

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 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.

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.

This study aimed to assess of efficacy of the kinesio-taping on male patients suffering from mutational falsetto

The purpose of this study is to assess subjects with muscle tension dysphonia for perceived effort and acoustic effects of gargle phonation compared to baseline and a sham water swallow.

This study will investigate and compare the air stream during voice production in patients with abductor spasmodic dysphonia and in normal volunteers. People with abductor spasmodic dysphonia have uncontrolled muscle spasms during speech, resulting in a weak voice. A better understanding of the abnormalities of this disorder may help in the development of more effective treatments. Healthy volunteers and patients with abductor spasmodic dysphonia may be eligible for this study. Candidates will have a physical examination and medical history. (Patients will be videotaped and voice-recorded during the medical interview for review by specialists who will identify the type and severity of their speech disorder.) All candidates will also undergo a procedure called flexible fiberoptic laryngoscopy to record the movement of the vocal folds during speech, breathing and other tasks such as singing, whistling and prolonging vowels. For this test, the inside of the nose is sprayed with an anesthetic (lidocaine) to numb the nasal cavity and a decongestant (oxymetazoline) to widen the nasal passage. Then, a thin flexible tube called a nasolaryngoscope is passed through the nose to the larynx (voice box). A camera attached to the eyepiece of the nasolaryngoscope records the movements of the vocal folds. Participants will then have an airway interruption test to detect pressure changes in the voice box during production of continuous sounds. A nose clip is placed over the subject's nose and two sensor devices are placed on the neck to pick up changes in movement and position of the vocal cords during voicing. A mouthpiece is placed in the mouth, and subjects are asked to say "ah" continuously at a specified sound level. This voicing is repeated 33 times with periodic breaks. Patients only will also be given an injection of botulinum toxin. These injections are effective, in varying degrees, in about 60 percent of patients with abductor spasmodic dysphonia. This study will use a different approach to botulinum toxin injections to test their effect in patients with pressures higher than normal. Rather than inject the posterior cricoarytenoid muscle or the cricothyroid muscle, as is typically done, the thyroarytenoid muscle, which closes the voice box, will be injected on one side. A second one-sided injection may be given after 2 or 3 weeks if no effect is seen after the first injection. Speech will be recorded at each visit to measure any change in symptoms after the injection.

The goal of this clinical trial is to determine and compare the effects of different voice therapy programs in children with vocal fold nodules. Vocal fold nodules are non-cancerous growths on the vocal folds which cause hoarseness. The main questions this trial aims to answer are: What are the short-term effects of the new voice therapy program 'straw phonation' and a more traditional 'resonant voice therapy' program on (a) the vocal quality, (b) the size of the growths on the vocal folds, and (c) the overall functioning in children with vocal fold nodules? During straw phonation exercises, you make sound through a drinking straw. During resonant voice therapy exercises or 'humming', you make an 'm' sound as you breathe out. What are the long-term effects of these voice therapy programs? Participants will receive a short-term intensive voice therapy program of four days. The researchers will compare the straw phonation group, resonant voice therapy group and control group to see if voice therapy works well in treating children with vocal fold nodules. The researchers hypothesize that straw phonation will have better results than resonant voice therapy. Straw phonation exercises are easier for children because they use an external tool (the straw) and less self-correction is needed.

This study will investigate the safety and efficacy of a silk protein microparticle-based filler for vocal fold injection augmentation to treat dysphonia/dysphagia secondary to vocal fold paralysis. Participants will receive one injection and follow-up for a planned period of 12 months.

The investigators will conduct a pilot experiment for a novel and personalized method for voice restoration using machine learning applied to surface EMG (sEMG) signal from articulatory muscles of the face and the neck allowing recognition of silent speech. The investigators predict that the use novel personalized method for voice restoration will be feasible and successful for patients.

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.
