Filter by: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.
When the retractor blades oped and is positioned to provide the surgical access in the anterior cervical spine surgery, it cause the trachea to deviate laterally and pose pressure on the tissue between the retractor and the trachea. This is convincible as revealed by the increase of cuff pressure of endotracheal tube. The study aims to investigate differences in the increase of cuff pressure after retractor is positioned between nasotracheal and orotracheal intubation.
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.
This study wants to investigate treatment for patients with common voice disorders where no surgical or medical treatment is needed. A voice disorder is when your voice is croaky, hoarse or when you lose it altogether. This can be a serious problem for people as it stops them from participating in their normal life (for example in their jobs, hobbies, family and wider social life). This study will look at our most commonly used method of treatment for voice problems. This method is based on physical exercises which work on the muscles which produce the voice. This voice work was originally developed by Jo Estill, a singer and scientist, and is widely used in voice coaching. Though many Speech and Language Therapists (SLTs) provide voice therapy based on the Estill model, there is no clinical evidence to support its use. The aim of this study is to test the design for a larger research study into the effects of voice therapy based on Estill model of voice. We want to find out if our tests work and are easy to use, and to check that the study methods are right and would work on a larger scale. It is a feasibility study, and therefore allows us to test whether this study can be done. Another important part of this study is to involve patients in developing research. We want to find out what patients think about the treatment they receive, and about taking part in a study. The way this study will work is that patients who have agreed to take part will have between four and six voice therapy appointments, just like they would if they were not part of the study. Voice test results from before and after treatment will be compared and carefully studied. After patients taking part in the study have finished their treatment, they will be asked about their experience of voice therapy, and of being in the study. Much of what will be done as part of the study is identical to what is normally done in treatment, however we will look in detail at all the tests, and we need permission from participants to use their test results and include their comments. It is important to learn more about voice therapy and to improve voice therapy for patients with this type of voice problem. By finding out more what patients think about the treatment we provide, what tests to use, and about how best to run a research trial, we will be able to plan further research and hopefully be successful at a next large research grant application.
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.
The aim of the project is to compare NBI endoscopy and standard endoscopic method using white light and evaluate accuracy both methods in early detection and diagnosis hypopharyngeal and laryngeal precancerous and cancerous lesions. A higher contrast between the mucosal epithelium and blood vessels is achieved in NBI endoscopy using filtered light comparing to white light observations. This allows detection of small mucosal changes, few millimetres in diameter, which are not observable using white light. The second aim in patients with squamous cell carcinoma of the upper aerodigestive tract is to compare extension of mucosal lesions by evaluation of NBI endoscopy and white light endoscopy, which is crucial for perform targeted biopsy and for determination of resection margins in cancer surgery. The investigators expect that dysplastic changes of mucosa or early laryngeal cancerous lesions are detected in white light endoscopy rarely. In case our hypothesis is confirmed, frequency of precancerous and early cancerous lesions of hypopharynx and larynx is more common in patients with non-specific symptoms of laryngeal and pharyngeal diseases.
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.
