Active clinical trials for "Sinusitis"

This study is intended to evaluate the efficiency of utilizing "dynamic implant valve approach" (DIVA) system in treating chronic maxillary sinusitis.

Functional endoscopic sinus surgery (FESS) is the gold standard surgical intervention for management of patients with chronic rhinosinusitis (CRS). Synechiae formation in the middle meatus is the most common complication of endoscopic sinus surgery after FESS. Nasal debridement is a postoperative procedure used in the prevention of synechiae formation. This procedure lacks standardized evidence-based guidelines. The currently existing studies that have been conducted to determine the efficacy of post-operative debridement have shown conflicting results. We hypothesize that there is no difference in short and long term clinical outcomes between patients who had routine post-operative nasal debridement following FESS and patients who did not have post-operative nasal debridement.

Impaired olfaction is one of the major complaints of patients with nasosinus polyposis, with nasal obstruction. In case of failure of medical treatment for patients with polyposis nasosinusal, they may use endoscopic surgery nasosinusal. Before surgery, 73% are hyposmic or anosmic, compared to 43% after surgery. Persistence of hyposmia or anosmia despite the removal of polyps can be explained by mechanisms inflammatory in the mucous membrane of the olfactory cleft. In addition, studies in mice have shown a degeneration of primary olfactory neurons at the level of the olfactory mucosa in connection with directly with TNF alpha, a pro-inflammatory molecule.

This is a randomized controlled first in man study. Study purpose is to assess safety and efficacy of Composite Removable Stent Composite Stent implantation post-endoscopic sinus surgery in terms of: Sinus tissue adhesions Middle turbinate lateralization into nasal septum i.e. postoperative opening reduction Inflammation

The purpose of this study is to determine whether Reslizumab is effective for the treatment of chronic sinusitis.

Chronic sinusitis (CRS) is a common inflammatory sinus condition among Canadians. Saline irrigation is an effective therapy used in the management of CRS and is a commonly prescribed treatment in preoperative surgery for people with this condition. Recently, a study performed by a Toronto group in Canada tried to show if there is any significant improvement between using high versus low volume saline irrigation to treat CRS. Despite finding a trend, the number of people with CRS used in this pilot study was not large enough to conclusively declare any difference between the two treatment groups. PURPOSE: The purpose of this study is to determine if there is a clinical benefit of high volume saline nasal irrigation (HVSI) over low volume saline irrigation (LVSI) in the postoperative period in patients with chronic Rhinosinusitis (CRS). This study is part of a multicenter collaborative project initiated by Macdonald et al. (20). A sample size of 176 participants (88 in each condition) is required to achieve data significance. To achieve this, our role is to collect data (plus those of four other Canadian rhinology research centres) from 20 patients and add our findings to theirs to establish an acceptable and significant result. This information would help otolaryngologists, family physicians, and other health care professionals recommend the best post-operative SNI (saline nasal irrigation) device for their patients with CRS.

The purpose of the study is to test the clinical efficacy of oral Vitamin D3 on Wound Healing in patients with Chronic Rhinosinusitis With Nasal Polyposis and Lower Vitamin D Levels After Endonasal Endoscopic Sinus Surgery

Rhinosinusitis is one of the most prevalent diseases within the United States and leads to decreased quality of life for patients suffering from this condition. A foundation in treatment for rhinosinusitis is nasal saline irrigations, which are administered through an irrigation bottle. The irrigation bottles are prone to contamination by bacterial and fungal species despite proper maintenance. A new commercially available irrigation solution has been created using chitosan, a natural polysaccharide with antibacterial and antifungal properties. This research project will examine the ability of chitosan to decrease or prevent contamination of irrigation bottles after 1 month use by adult patients with rhinosinusitis. Participants in this project will use either saline or chitosan irrigation solution for 1 month and then switch to the other solution for 1 month. Following 1 month of use, the irrigation bottles will be cultured to determine if chitosan irrigation solution decreased the contamination of the irrigation bottles.

Obtaining adequate hemostasis is crucial during endoscopic sinus surgery. Submucosal injection of local anaesthetic containing adrenaline has frequently been used to improve surgical milieu. However, injection of adrenaline has potential side effects including tachycardia, hypertension as well as inducing arrhythmia. The aim of this randomized clinical trial is to assess the hemodynamic and hemostatic effects of two different concentrations of adrenaline in local anaesthetic used during endoscopic sinus surgery.

The treatment of eosinophilic sinusitis with nasal polyps is difficult and challenging. After endoscopic sinus surgery(ESS), complications such as edema, scar formation, adhesions, sinus stenosis and recurrence of polyps are prone to occur. Investigators aim to assess the efficacy and safety of Steroid-eluting stent when implanted in sinus in patients following ESS with eosinophilic sinusitis and nasal polyps.The randomized, double-blind, controlled clinical trial enrolled patients with eosinophilic sinusitis and nasal polyps. After endoscopic bilateral sinus surgery, the Steroid-eluting stents were randomly implanted in one side of the sinus and the other side as a control. Primary outcomes are change in the Lund-Kennedy endoscopic score.The primary outcomes will be measured in baseline, week4,week 8 and week 12. Secondary outcomes include the changes in symptoms measured by Visual analog score and nasal patency (nasal airway resistance and nasal cavity volume), exhaled nasal nitric oxide. The investigators also evaluate change in inflammatory cytokines (interleukin(IL)-4, IL-5, IL-8, IL-17, IL-22, IL-25, interferon-γ, tumor necrosis factor-α, transforming growth factor-β, Leukotriene,Eotaxin) in nasal secretions. The secondary outcomes will be measured in baseline, week4, week8 and week12. Mucosal pathology assessment will be performed at 4 weeks postoperatively.Sinus CT scan will be conducted at 8 weeks after surgery. Changes in serum cortisol are monitored at baseline,week4 and week12 postoperatively. All adverse events are recorded throughout the experiment
