This Study Aims to Assess the Impact of 50°C Saline Irrigation on the Overall Intraoperative Blood Loss and Surgical Visualization During Endoscopic Sinus Surgery for Rhinosinusitis.

Objectives: Intraoperative bleeding during endoscopic sinus surgery for severe rhinosinusitis may significantly compromise the surgical field. Saline heated to 50°C promotes transient vessel vasodilation and mucosal edema without causing nasal mucosal necrosis. The brief thermal exposure may induce superficial protein denaturation and facilitate local hemostasis, thereby improving endoscopic visibility. This study aims to assess the impact of 50°C saline irrigation on the overall intraoperative blood loss and surgical visualization during endoscopic sinus surgery for rhinosinusitis. Methods: This prospective randomized controlled trial study is going to assign the patients to three groups. In the interventional hot saline group (HSI), intraoperative irrigation will be performed with heated saline at 50°C. In the room-temperature saline group (RTSI), saline at 22°C will be used; in the third one group (Control), no irrigation will be administered. Intraoperative blood loss will be recorded in milliliters and milliliters per minute of operative time, and the surgical field will be evaluated using the Boezaart scale. HSI is hypothesized to be more effective than RTSI in minimizing intraoperative bleeding during FESS.

BIOlogics in Severe Nasal POlyposis SurvEy.: a French Registry

With a prevalence of 2-4% in western countries, Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) is of major concern regarding its substantial impact on the social and physical quality of life. So far, endoscopic sinus surgery remains the treatment of choice when the first line of medical treatment with corticosteroid has failed. During the last 15 years, several studies have shown that CRSwNP is associated with a T helper 2 (T2) immune response leading to B cell release of IgE, mucosal recruitment of eosinophils from bone marrow via Interleukin (IL)-5, IL-4 and IL-13 mediated chemoattractant production. New biologic agents capable of blocking T2 cytokines have been developed in the field of eosinophil-associated diseases, shifting the paradigm of treatment for patients with CRSwNP. In the near future, endotype profiling with accurate biomarkers will be mandatory to tailor the treatment of nasal polyposis with specific biologic therapies. Herein the investigators propose a prospective study monitoring medical records of CRSwNP patients who undergo biologic treatments. The objectives are to assess treatment efficacy on quality of life, to report clinical and biological criteria for prescription and to measure tolerance and compliance.Patient-reported outcomes will be addressed according to their initial clinical profile (allergy, asthma, NSAID, gastroesophageal reflux disease, obstructive apnea, otologic disorder, smoke habit).

Evaluation of the Safety and Performance of a Bioresorbable Nasal Dressing Containing Mometasone Furoate

The objective of this study is to investigate the safety and performance of OCEAN® as an adjunct in wound healing after nasal/sinus surgery by using OCEAN® in patients undergoing nasal/sinus surgery.
