Introduction Congenital nasolacrimal duct obstruction (CNLDO) causes excessive eye tearing or mucoid discharge. Twenty percent of one-year-olds globally have CNLDO. There are many sources that offer information to parents. This study evaluates the quality and accuracy of CNLDO-related YouTube videos. Methods The first 100 videos that appeared after typing "congenital nasolacrimal duct obstruction" in the YouTube search engine were evaluated. These videos were also analyzed and scored using the DISCERN, Journal of the American Medical Association (JAMA), and Global Quality Scoring (GQS) systems. Results Forty videos met the inclusion criteria. The mean DISCERN score was 47.3 ± 9.15, JAMA was 1.72 ± 0.87, and GQS was 3.1 ± 0.81. The duration of the videos uploaded by the non-physician group was significantly longer (p = 0.04). In addition, the JAMA score of the videos uploaded by the physician group was significantly higher than that of the other group (p = 0.03). Theoretical videos were longer than surgical videos (p = 0.02). DISCERN, JAMA, and GQS scores were statistically higher in the theoretical video group (p = 0.002, p = 0.04, and p = 0.03, respectively). Conclusion According to our research, the quality of YouTube videos about congenital nasolacrimal duct obstruction is average. This information source can be improved by making videos with more detailed information about the disease and theoretical information, as well as by having health professionals look over the content that has been uploaded.

Purpose: To evaluate the effect of postoperative nasal triamcinolone spray use in primary endoscopic dacryocystorhinostomy using The Lacrimal Symptom Questionnaire .Methods: This study included a series of 50 consecutive retrospective cases with primary endoscopic dacryocystorhinostomy and with silicone stent implantation who were followed up for 6 months postoperatively. Patients using nasal triamcinolone spray for 3 months postoperatively were included in the triamcinolone group. Patients not using triamcinolone were included in the control group. Lacrimal stents were removed 3 months postoperatively. The Lacrimal Symptom Questionnaire (Lac-Q) was performed in the preoperative and postoperative 6th month. Anatomical success, functional success, and changes in lacrimal symptom and social impact scores were compared between the two groups 6 months after surgery.Results: Results of 48 endoscopic dacryocystorhinostomies performed on 48 patients (23 triamcinolone group, 25 control group) meeting the inclusion criteria were analyzed. The anatomical success rate (95.7% vs. 84.0%, p = 0.350) and the functional success rate (91.3% vs. 76.0%, p = 0.249) were higher in the triamcinolone group, but this difference was not statistically significant. No complications were observed in the triamcinolone group, whereas complications developed in two patients in the control group (p = 0.490). The mean change in total lac-Q score was 11.0 in the triamcinolone group and 9.0 in the control group (p = 0.011). The mean change in social impact score was 4.0 in the triamcinolone group and 3.0 in the control group (p = 0.005). Mean change in lacrimal symptom score was 6.0 in the triamcinolone group and 6.0 in the control group (p =0.368)Conclusions: Our study indicated that postoperative use of triamcinolone spray increases the success rate of endoscopic dacryocystorhinostomy. also revealed that triamcinolone may also lead to greater improvement in quality of life scores than the control group using a validated questionnaire.
