Filter by:Total arytenoidectomy is claimed to increase risk of aspiration and cause more voice loss than other operations performed for bilateral vocal fold paralysis (BVFP). However, objective evidence for such conclusion is lacking. There is no study comparing swallowing and voice after total and partial arytenoidectomy.
Recurrent laryngeal nerve dysfunction and hypoparathyroidism are well-recognized important complications of thyroid surgery. The duration of convalescence, after non complicated thyroid operation, may depend on several factors of which pain and fatigue are the most important. Nausea and vomiting occur mainly on the day of operation. Glucocorticoids are well known for their analgesic, anti-inflammatory, immune modulating and antiemetic effects. The investigators therefore undertook the present study to investigate whether preoperative dexamethasone could improve surgical outcome in patients undergoing thyroid surgery.
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 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.
To investigate the safety and efficacy of the no-tie technique using the harmonic scalpel (HS) in terms of the operating time and complications in total thyroidectomy with central neck dissection (CND). Recently, the HS has been used as an alternative to conventional hand-tied ligation for hemostasis in thyroid surgery, which is a time-consuming procedure. Very limited data have been published on evidence of its safety in total thyroidectomy accompanied by CND without supplementary hand-tied ligation.
Vocal cord paralysis is a common cause of congenital stridor and airway obstruction. In this study we plan to identify the genetic locus of the genes in two extended families who suffer of the disease.
Bilateral laryngeal reinnervation induces a rise in laryngeal resistance and speech alteration. The aim of this study is to propose laryngeal reinnervation by a phrenic nerve root to patients with bilateral laryngeal paralysis.
