Filter by:This study employs a multicenter, randomized controlled trial method, where patients meeting the inclusion criteria for subglottic stenosis are randomly divided into two groups. These groups are respectively undergoing translaryngeal endoscopic mucosal injection and ultrasound-guided injection of triamcinolone treatment. The comparison will focus on various indicators such as therapeutic effect, incidence of adverse reactions, treatment costs, and hospital resource utilization between the two groups. The safety and effectiveness will be compared to determine the relative merits of the two treatment methods.
Nasal continuous positive airway pressure (CPAP) acts as a 'pressure' bridge between spontaneous breathing and controlled mechanical ventilation. As a result, there is an increasing trend in the prophylactic use of nasal CPAP in pediatric patients following high-risk airway procedures to reduce postoperative airway complications. Still, there is no study published on the prophylactic use of balloon dilatation in children with tracheal stenosis.The study hypothesizes that implementing postoperative prophylactic CPAP in pediatric cases with subglottic stenosis undergoing balloon dilation may shorten recovery time and minimize airway complications.
To provide a novel therapy idea and method to solve the clinical problem of postoperative adhesion of bilateral vocal cords, patients enrolled in this study will be applied with curcumin on both wound sites of bilateral vocal cords after the surgery on the bilateral vocal cord endoscopically.
The trial evaluates the safety and efficacy of the olfactory mucosa-derived mesenchymal stem cells based therapy for the patients with chronic laryngeal and tracheal stenosis
The purpose of this phase 2 study is to examine if inhibiting IL-17A activation using the biologic drug Taltz, in idiopathic subglottic stenosis patients will decrease scar fibroblast proliferation therefore reducing or eliminating the need for invasive or repeat surgeries.
To improve diagnostic methods for patients with laryngeal stenosis for the optimal determination of the technique of surgical treatment.

This study aims to test a new groundbreaking treatment for narrowing of the voicebox and upper windpipe, which can be due to injury, inflammatory disease or cancer treatment. Narrowing of the voicebox or upper windpipe can leave patients dependant on a tracheostomy tube to breath through (a tube or hole in the neck), which can require a high level of care with regular hospital visits and can lead to recurrent chest infections. Regular surgical procedures may be necessary to widen the airway. Speaking may be very difficult or not even possible, breathing is usually a struggle and swallowing can also be affected. Patients feel very tired all the time. The new treatment tested by this study is an implant that will partially replace the voicebox or upper windpipe in order to cure the narrowing. The implant is based on a human donor voicebox or windpipe that has been processed with detergents and enzymes in order to remove all the cells from the donor, leaving a 'scaffold' of connective tissue. The patient's own stem cells are removed from the bone marrow, then are grown on the scaffold in the laboratory. These cells will form the cartilage in the wall of the scaffold. A split skin graft from the patient may be needed to line the inside of the implant. The implant can be considered 'living' due to the cells grown on it, and this type of treatment is referred to as 'tissue engineering' or 'regenerative medicine'. Once these cells have attached and started to grow on the scaffold, it is ready to be implanted into the patient, and an operation is performed which occurs in two separate stages. The final stage of the operation involves removing the narrow section of voicebox or upper windpipe and implanting the scaffold to reconstruct it. Patients will be followed up for two years after this operation, with investigations such as CT scans, examination of the voicebox and windpipe with a flexible camera (bronchoscopy) and blood tests performed at specific times. It is intended that this treatment will significantly improve patients' symptoms resulting in better breathing, swallowing and voice function, reducing the need for repeated hospital visits and procedures and enhancing patients' quality of life.
The investigators hypothesize that a functional computational model that simulates the mechanical and aerodynamic behavior of the upper airway in children with Pierre Robin Sequence (PRS) and laryngeal lesions (e.g. subglottic stenosis or SGS) can be used as an effective diagnostic and treatment planning tool.
This is a randomized, prospective, double-blind, placebo-controlled clinical trial of the use of mitomycin-C topical application as an adjunctive treatment in the endoscopic surgical treatment of patients with laryngotracheal stenosis. We hypothesize that the use of mitomycin-C improves patient outcome in the endoscopic surgical treatment of laryngotracheal stenosis.
