13 Clinical Trials for Various Conditions
Renuva is allograft adipose matrix commonly used as a filler in cosmetic procedures. The investigators are studying this material as an injectable in the vocal fold to treat glottic insufficiency. Currently, many products can be used as an injectable in the vocal fold to correct glottic insufficiency such as carbomethycellulose, hyaluronic acid, collagen derivatives and calcium hydroxyapatite amongst others. An ideal injectable would not impair the fibroelastic property of the vocal fold tissues and would integrate within the tissue of the vocal fold. Since Renuva has the property of stimulating adipogenesis by using growth factor and collagen, the investigators believe it could represent a good option in terms of safety and efficacy for vocal fold augmentation. This study will assess the safety and efficacy of Renuva as a vocal fold injectable to treat glottic insufficiency.
This is a prospective observational study examining the treatment outcomes of selective laryngeal reinnervation procedures for patients with bilateral vocal fold paralysis.
People who had paralysis of the vocal cords are often prevented from breathing by this problem because the cords will not open, and the patients have to wear a tracheostomy (neck breathing tube) to bypass this airway obstruction. This study examines the effects of vocal cord opening triggered by a pacemaker implanted over the chest wall. The device is connected to a nerve taken from a muscle close to the larynx (voice box) and implanted into the paralysed laryngeal muscle so it can reinnervate it. When this process is complete after a few weeks, the stimulator is turned on and the level of vocal cord opening is assessed. Airway improvement is checked by pulmonary function tests and measurements of vocal cord opening. The ultimate goal of the study is to lead to situations where patients with bilateral vocal fold paralyses could get rid of the neck breathing tube to have less complications, be more comfortable and socially acceptable.
The primary study goal is to evaluate the histological characteristic of Silk Voice to evaluate the potential for Silk Voice to deliver long-term results to patients.
The primary purpose of this project is to evaluate the safety of new treatment termed bilateral laryngeal pacing to improve treatment outcomes in patients with bilateral vocal fold paralysis (BVFP) (Aim 1). Outcome measures related to voice and ventilation will also provide initial insights into the efficacy of bilateral (Aim 2) and unilateral (Aim 3) stimulation of the implanted device to improve treatment outcomes in patients with BVFP.
The purpose of this study is to determine how often heart or chest surgery in children leads to problems with the movement of the vocal folds.
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.
Unilateral vocal fold paralysis (UVFP) is caused by injury to the nerve to the affected vocal fold. The injury to the vocal fold makes the affected person's voice sound "breathy". Voice therapy is usually tried first, and, if unsuccessful, surgical treatment is considered. The standard surgical treatment is called vocal fold medialization and aims to bring the injured cord to the midline. An alternative surgical treatment, vocal fold reinnervation, aims to bring a new nerve supply to the injured vocal fold. The reinnervation operation, which has some potential advantages over the medialization operation also requires several months for final results to be gained. The goal of this multicenter, randomized clinical trial is to see which of the two surgical treatments produces a better outcome. In order to participate in this study patients with UVFP must meet all entry criteria and must be released from voice therapy by a speech-language pathologist. Information collected for the study (pre-surgery, and at 6 and 12 months after surgery) includes voice recordings, movies made of vocal fold function, airflow and pressure measurements of the voicebox, and an outcomes questionnaire.
The purpose the study is to determine the genetic causes of specific voice disorders that run in families. Researchers are particularly interested in two conditions; 1. Spasmodic dysphonia 2. Vocal fold paralysis Familial vocal fold paralysis can be a life-threatening disorder that can cause difficulty with vocal fold movement for breathing and voice and sometimes for swallowing. Studies are ongoing at the NIH to better understand the pathophysiology and to relate it to the genetic pattern of inheritance. Families are being recruited to participate in these studies and are being provided with further information on the disorder and genetic counseling if desired. Physician referral is requested for affected members of families with vocal fold paralysis of an unknown cause occurring over at least 2 generations. All travel, lodging, examination and counseling costs are covered for both affected and unaffected members of a family. Examinations include: voice, laryngeal, neurological, electrodiagnostic testing, genetic counseling, and radiological studies....
The goal of this prospective, observational study is to evaluate for the presence of vocal fold motion impairment (VFMI) in the children admitted to the pediatric intensive care unit on noninvasive positive pressure ventilation (NIV PPV). Participants will have two ultrasounds of their vocal folds performed, once while on NIV PPV and once after weaned off of the NIV PPV. This results of these scans will be reviewed against one another and against the gold standard, fiberoptic nasolaryngoscopy (FNL). The main question this study aims to answer is: Can POCUS be used to reliably detect VFMI while pediatric patients on supported with NIV PPV?
This project is a first attempt to assess cough airflow dynamics and true vocal fold (TVF) adduction and abduction angles during voluntary cough to examine the effects of changes in glottal closure due to reduced mobility of one true vocal fold. The hypothesis of this study is that the incomplete glottal closure due to reduced vocal fold mobility will result in changes in true vocal fold adductory and abductory angles during cough and will result in changes to voluntary cough airflow parameters. This study results will contribute to the existing knowledge of the laryngeal contribution to cough airflow dynamics.
The purpose of this study is to see how the brain re-learns to control the larynx in speaking and swallowing when undergoing surgical rehabilitation in the form of either thyroplasty or vocal fold augmentation for unilateral vocal cord paralysis. What is needed is information on how the brain re-learns to control speaking and swallowing so that we can eventually learn how to help patients re-learn faster after their procedure. Functional Magnetic Resonance Imaging (or fMRI) will allow us to image your brain as you speak and swallow. We will produce "brain maps" for speaking, swallowing and hand movements.
In-office procedures (IOPs) are a cost-effective, and safe alternative to many operating room procedure, with benefits such as reduced anesthesia risk. One of the major causes of failed in-office procedures or requirement of conversion to the operating room is poor patient tolerance. Vibration and augmented reality (AR) can be used as non-pharmacologic treatment options to treat patient anxiety and pain by using the physiology proposed by the gate-way theory of pain as well as distraction. This study seeks to compare anxiety and pain perception with patient reported survey data, as well as physiologic indicators of stress such as heart rate variability (HRV) within patients undergoing IOPs in a laryngology office with and without vibration and AR treatment.
