Comparative Effectiveness of Xylometazoline (0.1%) vs. Normal Saline (0.9%) Irrigation on Post-Septoplasty Healing: A Meta-Analysis of Randomized Trials
摘要
Nasal decongestants like xylometazoline are widely used in postoperative care following septoplasty, yet their effectiveness in improving healing outcomes remains unclear. This meta-analysis evaluates the impact of xylometazoline compared to normal saline on post-septoplasty outcomes, including bleeding, crusting, nasal obstruction, pain, and patient satisfaction. PubMed, Google scholar, Cochrane, Scopus, and Web of Science were searched for relevant articles. A systematic review and meta-analysis were conducted following PRISMA guidelines. Randomized controlled trials (RCTs) comparing xylometazoline to normal saline in post-septoplasty patients were included. Data were extracted for key outcomes, including visual analog scale (VAS) scores for pain, crusting, and bleeding, as well as patient-reported nasal obstruction and satisfaction. Pooled effect sizes were calculated using random and fixed-effects models, and heterogeneity was assessed via I² statistics. Four RCTs (n = 338) met inclusion criteria. Meta-analysis demonstrated a significant reduction in bleeding (MD = −1.80; 95% CI −2.15, −1.45; p < 0.00001) and crusting (MD = −1.89; 95% CI −4.05, 0.27; p = 0.09) in the xylometazoline group. Nasal obstruction also showed a trend toward improvement but was not statistically significant (p = 0.06). Pain scores did not differ significantly between groups (MD = 0.03; 95% CI −0.85, 0.92; p = 0.94). Heterogeneity was moderate to high (I² range: 36−98%). Xylometazoline use post-septoplasty significantly reduces postoperative bleeding and crusting, with a potential trend toward improved nasal obstruction. However, no significant effect on pain was observed. Given the moderate-to-high heterogeneity, further high-quality RCTs with standardized outcome measures are needed to confirm these findings.
