Abstract:Objective To analyze the efficacy and recurrence rate of comprehensive standard treatment combined with functional endoscopic sinus surgery on moderate and severe polypoid-free chronic rhinosinusitis.Methods 92 patients with moderate or severe polypoid-free chronic rhinosinusitis from January 2017 to September 2018 were randomly divided into functional endoscopic sinus surgery. 46 patients in the control group and the comprehensive standard treatment combined with functional endoscopic sinus surgery were treated with the same drug treatment. The clinical treatment effect and recurrence rate were compared between the two groups.Results There were no significant differences in nasal sinus scores and nasal endoscopy scores between the two groups before treatment (P > 0.05). There was a statistically significant difference between the 6 months after treatment and the 12 months after treatment (P <0.05), the comparison between the groups was better than the control group, there was statistical difference (P < 0.05); there was no statistical difference between the two groups before treatment (P >0.05), 12 months after treatment the observation group was superior to the control group, and there was statistical difference (P < 0.05). The satisfaction and recurrence rates of the two groups were 95.65%, 4.35%, and 86.96%, 13.04%, respectively. The observation group was superior to the control group, there was statistical difference (P < 0.05).Conclusion Comprehensive standard treatment combined with functional endoscopic sinus surgery in the treatment of moderate and severe polypoid-free chronic rhinosinusitis can achieve the desired therapeutic effect and low recurrence rate, which is worthy of popularization.
