ABSTRACT
<p><b>OBJECTIVE</b>To explore the application of sinusitis mixture (SM) in endoscopic sinussurgery, thereby improving clinical curative rate of chronic sinusitis and nasal polyps.</p><p><b>METHODS</b>A totalof 50 chronic sinusitis patients were equally assigned to the experimental group (nasal douching by SM)and the control group (nasal douching by Compound Sodium Chloride Injection). Mucosa tissue 0.1 cmbefore natural opening was collected before surgery, at week 4, 12, and 24 after surgery. Changes ofmucosa cilia cells, goblet cells, stroma of mucosal membrane, inflammatory cells, and mucous glandwere observed. The numbers of goblet cells in the upper epithelia and ciliated cells, as well as their ratioswere calculated.</p><p><b>RESULTS</b>There was statistical difference in cavity cleaning time, cavity mucosal epithelization time, numbers of goblet cells in the upper epithelia and ciliated cells, as well as their ratio between the two groups (t = -2.342, -2.015, -2.145, respectively; P < 0.05).</p><p><b>CONCLUSION</b>SM could effectively promote and accelerate cleaning and mucosal epithelization of functional endoscopic sinus surgery, and significantly promote mucosal ciliary structure and function recovery of ostium-meatus nasicomplex.</p>
