ObjectiveTo investigate the clinical effect of radical sinus surgery combined with nasal irrigation in the treatment of refractory sinusitis. MethodsA total of 78 patients with refractory sinusitis were selected, and they were randomly divided into control group and study group, with 39 cases in each group. The control group received functional endoscopic sinus surgery, while the study group received radical sinus surgery combined with nasal irrigation. The clinical efficacy, related clinical scores before and after treatment, and the complications and recurrence were compared between the two groups. ResultsThe study group yielded a higher total effective rate (92.31% vs. 71.79%), a lower incidence of complications (17.95% vs. 38.46%), and a lower recurrence rate (12.82% vs. 41.03%) as compared to the control group (all P＜0.05). After treatment, the Lund-Kennedy scores and VAS scores of overall symptoms in the two groups were lower than those before treatment, and the above scores of the study group were lower than those of the control group (all P＜0.05). ConclusionRadical sinus surgery combined with nasal irrigation can achieve a superior therapeutic effect for patients with refractory sinusitis, which can improve the clinical symptoms, relieve discomfort, and decrease the incidence of complications and recurrence in patients.
