Abstract:Objective To study and analyze the effect of nasal endoscopic absorbable drug stent surgery on nasal microflora and prognosis in patients with chronic sinusitis with nasal polyps.Methods 80 patients with chronic sinusitis and nasal polyps from November 2018 to March 2021 were selected in this study. According to the random number table method, they were randomly divided into two groups, which were the experimental group and the control group. There were 40 people in each group. Patients in the control group were received nasal endoscopic Messerklinger minimally invasive surgery, while patients in the experimental group were received an absorbable sinus drug stent before the nasal endoscopic Messerklinger minimally invasive surgery. The hospitalization time, the recovery time of the nasal mucosa and the ventilation recovery time of the two groups of patients were compared, and the effects of different treatment methods on the nasal mucosa flora were compared. The curative effects were compared based on the clinical manifestations of all the patients after 3 weeks.Results The hospitalization time, the recovery time of the nasal mucosa, and the recovery time of the nasal cavity in the experimental group were significantly less than those in the control group (P < 0.05). The positive rates of Campylobacter and Enterococcus in the nasal cavity of the experimental group were significantly lower than those in the control group (P < 0.05); Pseudomonas, Haemophilus and Staphylococcus in the nasal cavity of the experimental group had no statistical significance compared with the control group after surgery (P > 0.05). The postoperative treatment effect of the experimental group was significantly better than that of the control group (P < 0.05).Conclusion The treatment of chronic sinusitis with nasal polyps with absorbable sinus drug stents under nasal endoscopy can significantly promote the epithelialization of the nasal mucosa and reduce the positive rate of Campylobacter and Enterococcus in the nasal cavity after surgery. The therapeutic effect is significant and it is worthy of clinical promotion application.
