Chronic inflammation in lacrimal sac tissue significantly impacts endoscopic endonasal dacryocystorhinostomy (En-DCR) outcomes. Severe inflammation is linked to higher rates of surgical failure, suggesting its role in En-DCR success.
Area of Science:
- Otolaryngology
- Ophthalmology
- Pathology
Background:
- Endoscopic endonasal dacryocystorhinostomy (En-DCR) is a surgical procedure to treat nasolacrimal duct obstruction.
- Factors influencing En-DCR success require further investigation.
Purpose of the Study:
- To investigate the correlation between chronic inflammation in lacrimal sac specimens and the surgical outcomes of En-DCR.
- To determine if histopathological features of chronic inflammation predict En-DCR success.
Main Methods:
- Analysis of 25 primary En-DCR cases and their lacrimal sac specimens.
- Histopathological examination for inflammatory cell infiltration, fibrosis, and capillary proliferation.
- Development of a 'chronic inflammation score' based on histopathological grading.
- Statistical comparison of inflammation scores with subjective and objective surgical outcomes.
Main Results:
- Overall En-DCR success rate was 60%.
- 90% of patients with unsatisfactory or unsuccessful outcomes exhibited severe chronic inflammation.
- Significant differences in inflammatory cell infiltration, fibrosis, capillary proliferation, and chronic inflammation score were observed between successful and unsuccessful outcomes (p < 0.05).
Conclusions:
- Histopathological features of chronic inflammation play a role in En-DCR outcomes.
- A chronic inflammation score can serve as a predictive indicator for En-DCR success.
