Advantages of rinsing the nasal cavity with a large volume of fluid in the postoperative period in patients with severe nasal polyposis before instillation into the nose

Objective: to determine the effectiveness of rinsing the nasal cavity with a large volume of mineral-vegetable isotonic solution using an individual device in the postoperative period in patients with severe chronic rhinosinusitis with polyps and compare the results of the study with the effectiveness of copious instillation of the same solution into the nasal cavity. Material and methods. The study included 45 people aged 28-49 years after endoscopic pansinusotomy. In the postoperative period, 2 groups were identified: in group 1 ( n =33), the nasal cavity was rinsed using an individual device with a mineral-vegetable isotonic solution (recipe No.1) with a volume of 240 ml and a temperature of 36 °C 2 times a day. In group 2 ( n =12) - copious instillation of the same solution (20 ml in each half of the nose) was performed 4 times a day. The effectiveness of nasal breathing was evaluated according to the Visual Analog Scale and the Sino-Nasal Outcome Test 22 questionnaire and the degree of crust formation on days 5-6, 14.
