Chronic rhinosinusitis is an inflammatory disease of the sinonasal mucosa with significant impact and limited treatment options. Chronic rhinosinusitis (CRS) poses an important public health problem and causes a large impact on individual quality of life. Studies of CRS have been limited by access to tissue, the complexity of the sinonasal physiology, a lack of available biomarkers, the absence of useful animal models, a paucity of cohorts with biological samples for analysis, and limited well-designed clinical trials or investigations of immune function. Therefore, novel strategies for identifying biological mechanisms underlying this disease are in great need. Using prospective samples from well characterized subjects, the investigators intend to profile the mucosa associated-bacteria in the nose and sinuses. In parallel, using sinus tissue from patients undergoing surgery, the site will interrogate the epithelium for mucosal immune function to understand host-microbe interaction. This study hypothesizes that the microbial profile of the sinuses initiates an immune responses which leads to chronic inflammation in susceptible people. This study would provide the first comprehensive data on what bacteria are present in the nose and sinus and could lead to important knowledge useful in sinonasal disease.
NCT03970655
The aim of this study is to evaluate the effect of the addition of epinephrine to bilateral real time ultrasound guided pterygopalatine ganglion blocks on intra-operative bleeding and blood loss during functional endoscopic sinus surgery (FESS).
NCT05427695
The purpose of this randomized study will be to determine whether topical probiotic sinus irrigations are more effective compared to saline sinus irrigation controls in the treatment of active CRS in patients who have had prior sinus surgery based on subjective and objective outcome measures.
NCT05287217
The safest and most effective post-operative pain control regimen after functional endoscopic sinus surgery (FESS) has been the subject of persistent research. This prospective study will compare post-operative pain control when managed either by a defined medication schedule or medication taken on an as-needed basis after functional endoscopic sinus surgery for chronic rhinosinusitis. Prior to surgery, patients will be randomly selected to be in one of two treatment arms. One group will receive instructions to take specific medications (acetaminophen and ibuprofen on a specific schedule post-operatively. The second treatment groups will be instructed to take the same medications but on an as needed basis for pain. Patients will also be provided with an option of a limited supply of narcotic analgesics for pain should they be needed. Post-operative pain control will be assessed by the patient with a pain-diary documenting perceived levels of pain for 10 days post-operatively using a validated visual analog scale. At the conclusion of the study the records of medications taken along with pain responses will be compared between groups
NCT03825757
The study is performed as a randomized double-blinded prospective controlled trial. A total of 72 adult Acetyl salicylic acid (ASA) -exacerbated respiratory disease (AERD) -patients with uncontrolled chronic rhinosinusitis with nasal polyps (CRSwNP) will be recruited. Those negative to ASA-challenge test will not enter the Clinical Trial . All patients entering the Clinical Trial, have undergone earlier ethmoidal surgery (partial/total) and have not gained disease control. F-helicobacter antigen is tested and treatment is given if indicated. The patients are recruited at the Helsinki University Hospital (HUH). The study will be monitored by a professional monitor. Electronic CRF and paper/electronic patient questionnaires provided by HUS will be used (eCRF and patient questionnairea, Granitics).

Chronic Rhinosinusitis (CRS) is a chronic inflammatory condition of the nasal passage and paranasal sinuses that places significant burden on affected patients and global healthcare systems. Current treatments for CRS such as long-term antibiotics, anti-inflammatory drugs, and surgery often reduce symptoms and signs of disease temporarily, however long-term results are much less satisfactory. Recently, the theory of a damaged microbiome (dysbiosis) as a cause or promoting factor behind CRS has gained increasing evidence from the scientific community. A condition of the gut with microbial dysbiosis (c.difficile) has previously employed microbiota transplant treatment with great success in long-term health outcomes. Such treatments are shown to repopulate bacterial microenvironment and restore protective commensal bacterial load. A pilot study conducted by this study team trialed a novel intervention of a Nasal Microbiota Transplant in a small group of participants. Preliminary results suggested significantly improved CRS symptoms after treatment with a healthy donor microbiota transplant, compared to the pre-transplant baseline. The addition of a randomized-control trial with inclusion of a placebo group is the next step. In this study, investigators aim to perform a two-arm, double-blinded, phase II randomized controlled clinical trial in order to assess the efficacy of a Nasal Microbiota Transplant against a placebo in a cohort of CRS patients without Nasal Polyps (CRSsNP).

The work compares the effect of different various values of arterial blood pressure on the clarity of the surgical field in pansinusoperation in patients with chronic rhinosinusitis.
NCT03599271
The objective of the ASCEND Study is to assess the safety, performance, and efficacy of the Intersect ENT UP Drug-Coated Device when used in chronic rhinosinusitis (CRS) patients undergoing balloon dilation of frontal sinus ostia (FSO)
NCT01525862
A prospective, single-arm, post approval pilot study.
NCT03427502
Postoperative agitation is an important complication of general anesthesia, moreover, it has been found with high incidence in ear, nose, throat (ENT) surgeries. We aim to study whether anterior ethmoidal nerve block will be successful in reducing postoperative agitation in those patients. Study population will be randomized into two groups, treatment and control group. Anterior ethmoidal nerve block will be done in treatment group and postoperative agitation compared between these two groups. Agitation score will be scored with Riker Sedation-Agitation Scale (SAS). Ho: Occurrence of post-operative agitation in patients undergoing nasal surgery with nasal pack under general anesthesia is equal in those with ethmoidal nerve block as compared to those without the block. Ha: Occurrence of post-operative agitation in patients undergoing nasal surgery with nasal pack under general anesthesia is not equal in those with ethmoidal nerve block as compared to those without the block.
NCT04097613
Povidone Iodine solution is a nasal antiseptic. Its application has been shown to be clinically safe, tolerable and effective against bacteria and fungi associated with chronic rhinosinusitis. This study will evaluate the effectiveness of Povidone Iodine in this hard-to-treat patient group. Furthermore, the study will also further evaluate any side effects that may occur with the use of Povidone Iodine.
