Filter by:In patients undergoing total thyroidectomy, intraoperative nerve monitoring according to the International Standards Guideline Statement may detect nerves more susceptible to injury. The aim of our study was to evaluate the independent risk factors of vocal cord palsy, including those related to pre-dissection nerve monitoring values. Methods: Prospective observational study in 95 consecutive adult patients undergoing elective total thyroidectomy in Spain. A single experienced phonologist performed a videostroboscopy (VS) exam preoperatively and one week after surgery to assess vocal cord mobility. Each surgical procedure was performed with intermittent intraoperative neuromonitoring. Latency and amplitude values were obtained for the vagal and recurrent laryngeal nerves before surgical dissection and compared with the postoperative VS exam.
The study tries to see the effect of using a combination of platelet-rich fibrin (PRF) and autologous fat as a filler for injection laryngoplasty procedures to treat unilateral adductor vocal cord paralysis.
A feasibility study to identify the immediate effect on the voices of patients with voice disorders (muscle tension dysphonia, vocal fold palsy or presbylaryngis) produced by exercising with Acapella Choice as a form of semioccluded vocal tract exercise (SOVTE).
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.
Larynx performs important functions of the aero-digestive tract, it has vital role in control of breathing, phonation, deglutition and protection of lower respiratory tract from aspiration. Vocal cord paralysis is a common and at times debilitating laryngeal dysfunction that has great social and economic impact on patients life. Medialization thyroplasty (MT), if done accurately and up to the expectations of the patient is very rewarding. However different materials with some modifications in the technique of the classical Isshiki type 1 thyroplasty is in practice, each with its own profile of benefits and disadvantages. Most of them are costly and out of reach of general population. In this regard, we aim to test a prolene mesh implant, which is easily available and can be placed with relative ease.
In the present study, the severity of recurrent laryngeal nerve injury (RLNI) and hypocalcemia (H) will be followed-up and the probable interrelation between them will be proposed considering the clinical situation of patients, e.g. improvement in hypocalcemia also make a positive effect on voice? (any objective sign? Ca? PTH?), return of voice is parallel with the improvement in hypocalcemia? Postoperative calcium (Ca), parathyroid hormone (PTH), regular vocal cord evaluations by ear-nose-throat (ENT) exams, deterioration-stability-improvement of clinical symptoms regarding both Ca metabolism and vocal cord function will be noted at regular intervals (postoperative day 1-3-first, weekly control/first month, monthly/first 6-month, 3-monthly/6-12 months) at outpatient controls. Serum Ca, PTH, ENT evaluation of vocal cords-noted.
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.
This is a prospective observational study examining the treatment outcomes of selective laryngeal reinnervation procedures for patients with bilateral vocal fold paralysis.
One of the major risks of endocrine surgery is recurrent nerve palsy (RNP), leading to vocal folds (VF) immobility. It happens in 5% of cases, leading to high morbidity: dysphonia, aspirations, impossibility to work. Guidelines recommend to systematically perform a nasofibroscopy before and after surgery to check vocal fold mobility. However, due to the decreasing number of specialists, the cost of decontamination, and discomfort of this procedure, these guidelines are insufficiently followed. Transcutaneous Laryngeal Ultrasonography (TLU) appears a good alternative to nasofibroscopy in evaluating VF mobility, as assessed by the recent flourishing literature. Our team is a leader in this research by having developed a dedicated software, which provides objective measures of VF mobility. The aim of the present protocol is to validate the power of TLU for the diagnosis of RNP on a large cohort of patients operated on endocrine surgery. It is a prospective multicentric study that will blindly compare TLU and nasofibroscopy, the latter being the gold standard. TLU is cost effective and painless; its learning curve is fast. If validated, it may be offered as a good alternative to nasofibroscopy in RNP detection and prognosis.
The purpose of this preliminary study is to help clarify our hypotheses for the longitudinal study by investigating the relationship between vocal cord paralysis and central auditory processes and thus the interpretation of auditory inputs into the central nervous system.
