Endoscopic Dacryocystorhinostomy (DCR) has become an acceptable alternative to the open approach, with considerable data demonstrating comparable success rates and advantages such as avoiding skin incisions. Drug-eluting bio-absorbable materials are relatively new innovation in sinus surgery, the usefulness of such materials in Endoscopic DCR is yet to be described.A retrospective analysis of 253 endoscopic DCR procedures performed by a single surgical team from September 2011 to June 2020 was performed. At the end of 2013, a surgical modification took place with the introduction of steroid-eluting Spongostan to the intranasal surgical bed. As a result, 2 cohorts were compared before and after the modification. The first cohort consisted of 55 patients, and the second consisted of 187 patients, respectively. Patient demographics, clinical features, complications and outcomes were examined.A total of 242 procedures were evaluated after exclusion. In the first cohort of 55 patients (48 adults and 7 children), the overall and adult functional success rates were 83.6% and 83.3%, respectively. In the second cohort of 187 patients (167 adults and 20 children), where steroid-eluting Spongostan was used, the overall and adult functional success rates were 92.5% and 93.4%, respectively. These differences were statistically significant.This is a unique study presenting a single surgical team's experience over a 9-year period where a novel technique involving drug-eluted bio-absorbable material (Spongostan) was introduced midway through, creating 2 cohorts to compare. Success rates were significantly higher after applying steroid eluted Spongostan to our endoscopic DCR technique. |
