Abstract:Objective To investigate the effects of endoscopic sinus surgery combined with glucocorticoid infiltration on long-term efficacy and nasal function in patients with chronic rhinosinusitis with nasal polyps. Methods From May 2015 to March 2018, 112 patients with chronic rhinosinusitis and nasal polyps in our hospital were selected as the study subjects. According to the random number table method, they were divided into the combined group and the control group, 56 cases in each group. The control group was treated with endoscopic surgery, and the combined group was treated with endoscopic surgery combined with glucocorticoid infiltration. The scores of the two groups before and 2 months after treatment, nasal ventilation function, nasal mucociliary clearance, and complications and recurrence were recorded. The clinical efficacy was analyzed. Results After treatment, the difference in Lund-Mackey, SNOT-20, and Lund-Kenndey scores between the patients in the combined group and the control group was statistically significant (P < 0.05); the complication rate and recurrence rate in the combined group were 5.36% and 3.57%, respectively. The complication rate and recurrence rate of the control group were 12.50% and 8.93%, respectively, and the differences were statistically significant (P < 0.05); the complication rate and recurrence rate in the combined group were lower than the total effective rate of the control group in the combined group of 92.86%, and the total effective rate of the control group was 83.93%, the difference was statistically significant (P < 0.05); after treatment, the difference between the nasal ventilation function index of the combination group and the control group was statistically significant (P < 0.05); the differences of the nasal mucociliary clearance function index of the combination group after treatment were compared with the control group by t test, and the difference was statistically significant (P < 0.05). Conclusion Endoscopic surgery combined with glucocorticoid infiltration for the treatment of chronic rhinosinusitis with nasal polyps is effective, can significantly improve the patient’s clinical symptoms, nasal ventilation function and nasal mucociliary clearance function, and has less complications and lower recurrence rate, which is worthy of clinical promotion.
