Abstract:Abstract: Objective To investigate the clinical effect of endoscopic sinus surgery combined with sihuang lavage solution in patients with chronic sinusitis, and its impact on inflammatory cytokines. Methods 64 cases of patients with chronic sinusitis were enrolled from May 2016 to March 2017, which were divided into control group (n = 32) and observation group (n = 32) randomly. The control group was treated with nasal endoscopic surgery, and the observation group was treated with nasal lavage with sihuang lavage solution after endoscopic sinus surgery. The levels of high-sensitivity C-reactive protein (hsCRP), tumor necrosis factors-α (TNF-α) and immunosorbent assay (IL-6) were measured. The complications during the follow-up were recorded. Results The effective rate of the observation group was 96.9%, which was higher than that of the control group (81.3%), and the difference was statistically significant (P < 0.05). After treatment, the levels of hsCRP, TNF-α and IL-6 in the observation group were lower than those in the control group (P < 0.05). There was no significant difference in the incidence of complications between the two groups (P > 0.05). Conclusion Endoscopic sinus surgery combined with sihuang lavage solution is better for chronic sinusitis patients, and it is helpful to reduce the level of inflammatory cytokines.
