Abstract
Abstract
Purpose: This study compared the success rate and complications of adjuvant use of mitomycin C (MMC) and triamcinolone (TA)-impregnated biodegradable nasal packing in endoscopic dacryocystorhinostomy(DCR). We also evaluated the efficacy of the combined use of intraoperative MMC and TA-impregnated biodegradablenasal packing for endoscopic DCR.
Methods: We retrospectively reviewed the data of 198 eyes from 148 patients who underwent endoscopic DCR for acquired nasolacrimal duct obstruction. The patients were randomly divided into three groups. Group A included patients treated without intraoperative MMC but with TA-impregnated nasal packing. Group B included patients treated without TA but with intraoperative MMC and normal saline-impregnated nasal packing. Group C included patients treated with intraoperative MMC with TA-impregnated nasal packing.
Results: The results revealed no significant difference in the overall success rates between groups A (86.8%) and B (89.2%) (p = 0.377). However, group C (97.5%) showed a higher overall success rate than groups A and B, with statistically significant differences. The incidence rate of granulomas was significantly lower in group C (5%) than in groups A (20.8%) and B (15.2%) (p = 0.009). Other complications, like crust, synechiae, and revision surgery, did not differ significantly between the three groups.
Conclusions: The combined use of intraoperative MMC and TA-impregnated absorbable nasal packing was effective in preventing granulomas and enhancing the surgical success rate.Additionally, single use of MMC or TA nasal packing was not statistically different.
