Objective:To evaluate the clinical efficacy of topical nasal Pomegranate Fruit Extract (PFE) for Chronic Rhinitis (CR), Chronic Rhinosinusitis with Nasal Polyposis (CRSwNP), and Chronic Rhinosinusitis without Nasal Polyposis (CRSsNP). Methods:Prospective, double-blinded, randomized study including 111 consecutive patients, between April 2012 and January 2017, afflicted by CRSwNP, CRSsNP, and CR. Patients from each group were randomly assigned to either PFE treatment or placebo twice daily for 30 days. Therapeutic efficacy was assessed by Ear Nose and Throat, blood and tomographic examinations, and the SNOT-20 questionnaire. Results:CR patients treated with PFE suffered significantly less from thick nasal discharge, difficulty falling asleep, reduced productivity, reduced concentration, and sadness (P= .004, P= .02, P= .03, P= .007 and P= .02, respectively). Conclusions:Topical nasal PFE was found to have some benefits for CR patients, however, not for CRS with or without Nasal Polyposis.

Background: Puncture and lavage of the paranasal sinuses, previously the primary treatment for unresponsive acute bacterial rhinosinusitis before surgery, has been abandoned due to procedural discomfort and advancements in antibiotic efficacy and endoscopic surgery. The rise in antibiotic-resistant bacteria has renewed the interest in minimally invasive sinus lavage to both avoid aggressive surgical interventions and identify appropriate antibiotic therapy. In this article, we describe the safety and feasibility of a new device in human patients and evaluate its efficacy as a treatment before the traditional sinus surgery in acute rhinosinusitis.Methods: The device with its seeker-shaped guiding tube and rotating wire can enter the sinus cavity through the natural ostium, pulverize the inspissated mucus, and enable lavage and culture sampling without the need for sinus puncturing. It was tested in 6 patients with chronic sinusitis under general anesthesia during endoscopic sinus surgery and in additional 10 patients with maxillary acute bacterial rhinosinusitis in outpatient settings under local anesthesia.Results: The device enabled rapid, efficient, and atraumatic insertion of the wire into the occluded sinuses. The rotating wire permitted pulverization of the thick mucus, which enabled irrigation without mucosal damage or adverse events. Overall, 9 of 10 patients with acute bacterial rhinosinusitis demonstrated remarkable improvements and were discharged the following day with no acute symptoms. The visual analog scale score for pain dropped from 8.9 to 0.4. The remaining one patient underwent endoscopic sinus surgery subsequently. None of the patients treated during endoscopic sinus surgery developed any adverse events.
