Comparison of Sinus Distribution between Nasal irrigation and Nasal spray Using Fluorescein‐labeled in patients with Chronic Rhinosinusitis: A Randomized Clinical Trial

alexandrossfakianakis shared this article with you from Inoreader Comparison of Sinus Distribution between Nasal irrigation and Nasal spray Using Fluorescein‐labeled in patients with Chronic Rhinosinusitis: A Randomized Clinical Trial via Clinical Otolaryngology Abstract Objective This study aims to compare the potential sinus distribution between high-volume nasal irrigation and nasal spray in chronic rhinosinusitis (CRS) patients who have not undergone sinus surgery. Design and Setting A randomized clinical study was conducted at the Otolaryngology-Head & Neck Surgery Department, Ramathibodi Hospital, Faculty of Medicine, Mahidol University. Participants Forty patients undergoing endoscopic sinus surgery (ESS) for CRS. Thirty-eight patients met the inclusion criteria and were randomly assigned to receive nasal irrigation or nasal spray mixed with fluorescein sodium preoperatively. Main outcome measures The primary outcome was the mean difference in the staining score of fluorescein in all sinuses between the two groups. Results The total fluorescein staining score for all sinuses in the nasal irrigation group was significantly higher than the score from the nasal spray group, with a mean difference score of 2.90, 95%CI: 1.22-4.58, p-value 0.001. The most significantly affected sinuses were the maxillary and the anterior ethmoid sinuses, while the frontal and sphenoid sinuses had only minimal staining from both techniques. Conclusion Nasal irrigation is a potential route to deliver drugs into the sinus in unoperated CRS patients. However, it is not considered a superior method to nasal spray at the most challenging anatomical areas, i.e., the frontal and sphenoid sinuses. View on Web
