Influence of hyaluronan nasal dressing on clinical outcome after endoscopic sinus surgery: A systematic review and meta-analysis.

INTRODUCTION: Hyaluronan nasal dressing might be promising in promoting reepithelialization after endoscopic sinus surgery (ESS). However, the results remain controversial. We conducted a systematic review and meta-analysis to explore the effects of hyaluronan nasal dressing on clinical outcome after ESS.

METHODS: Medical literature data bases were systematically searched. Randomized controlled trials (RCT) that assessed the effect of hyaluronan nasal dressing on the outcome after ESS were included. The results were searched and data were extracted and assessed for quality. The primary outcome was reepithelization. Meta-analysis was performed by using the random-effect model.

RESULTS: Four RCTs, which involved 352 patients, were included in the meta-analysis. Overall, compared with control intervention, hyaluronan nasal dressing significantly promoted reepithelization (odds ratio [OR] 3.18 [95% confidence interval {CI}, 1.33-7.59]; p = 0.009) and reduced edema (OR 0.45 [95% CI, 0.23-0.89]; p = 0.02) after ESS. However, hyaluronan nasal dressing failed to reduce synechia (OR 0.45 [95% CI, 0.19-1.03]; p = 0.06), crust (OR 1.00 [95% CI, 0.20-5.09]; p = 1.00), and infection (OR 0.84 [95% CI, 0.46-1.53]; p = 0.56) compared with the control group in patients who underwent ESS.

CONCLUSION: Compared with "Control intervention" indicates standard nasal dressing without hyaluronan, resorbable hyaluronan nasal dressing could significantly improve reepithelization and decrease edema but had no influence on synechia, crust, and infection after ESS.
