Abstract: Objective To explore the effect of different packing materials on sinus mucosa with chronic rhinosinusitis after endoscopic sinus surgery. Methods A total of 167 patients with chronic rhinosinusitis were divided into the fragmentable nasal dressing group A(n=93)and the swell sponge group B(n=74). Using Lund-Mackay CT scoring system, visual analogue scales(VAS)and Lund-Kennedy endoscopic scoring system, all patients were assessed in recover in pre-operation period, and the second week, the fourth week, and the twelfth week after the surgery. The data were analyzed by SPSS18.0 statistics software to compare the differences of outcomes of sinus mucosa. Results There was no difference about Lund-Mackay CT scores, the VAS scores and Lund-Kennedy endoscopic scores in two groups before surgery(P>0.05). About Lund-Kennedy endoscopic scoring, the scores of the two groups presented significant difference(P<0.01). Comparing with the scores of the second week, the scores of group A of the fourth week, and the twelfth week were lower than those of the group B(P<0.01). The VAS scores of group A were all significantly different from those of group B at same period(P<0.01), and the scores of group A at the post-operative 4 and 12 week were lower than those of group B. 5 cases of group A and 7 cases of group B had sinus region oedema seriously, ves hyperplasy and polypus recurrence. After individualized treatment, sinus mucosa presented recovery tendency. Conclusion Applying of fragmentable nasal dressing can promote preferable outcomes of sinus mucosa with chronic rhinosinusitis after endoscopic sinus surgery.
