Efficacy analysis of use of absorbable sinus drug stents in functional endoscopic sinus surgery

Abstract

Objective:To explore the efficacy of functional endoscopic sinus surgery（FESS） with an absorbable sinus drug stent in the treatment of chronic sinusitis. Method:107 patients with chronic sinusitis who underwent FESS were divided into two groups: 58 patients were set as stent group who were treated with sinus drug elution during surgery; 49 patients who did not receive a sinus drug stent were included in the non-stent group. The same postoperative treatment were used in the two groups. The patients were followed up for 1 month and reviewed 3 months after surgery. Efficacy is mainly evaluated by endoscopy. The evaluation indicators include whether the sinus mucosa is congested and edema, whether there is adhesion in the middle turbinate, whether vesicles or polyp-like mucosa are formed, whether the sinus mouth is stenosed or reoccluded, whether the sinus mucosa is epithelialized, and whether the patient had intervention after surgery. Result:Stents were successfully implanted in 58 patients in the stent group. The difference of the above six indexes between the stent group and the non-stent group was statistically significant at 1 month after operation. The postoperative complication rate and postoperative intervention rate were significantly lower in the stent group than in the control group（P<0.01）, the incidence of sinus mucosal epithelialization in the stent group was significantly higher than that in the non-stent group（P<0.01）. The sinus mucosal epithelialization were all completed in both groups after 3 months of surgery. The postoperative complication rate and postoperative intervention rate were significantly lower in the stent group than in the non-stent group（P<0.05 or P<0.01）. Conclusion:FESS combined with the absorption of sinus drug stents for the treatment of chronic sinusitis is safe and effective which can control the complications further after surgery while relieving the clinical symptoms of patients with sinusitis effectively.
