Background: Epiphora is a medical condition where a patient suffers from excessive tearing due to the blockage in the nasolacrimal system. Our study evaluates the use of stent and drill on the success rate, recurrence rate of symptoms, and the duration of dacryocystorhinostomy operation.
Methodology: We have summarized the cases of 86 patients from both Otolaryngology and Ophthalmology departments, Suffering from epiphora and underwent dacryocystorhinostomy. The results were further categorized based on age, gender, history of recurrent infection, and positivity of the regurgitation test. Cases were then studied for the response toward the method employed and their effect on the success rate. All the analyses were statistically validated.
Results: We observed no statistical significance of using a bone drill on the success rate of dacryocystorhinostomy (DCR). Otolaryngologists mainly used the drill, and it significantly increased the operation time. Additionally, otolaryngologists took longer to operate than ophthalmologists. The average operation duration was significantly higher where the bone drill was used. We found no statistical relevance of using a stent based
on the long-term response of the patient. However, patients showed significant improvement in the immediate response after the operation was performed with a stent.
Conclusion: Our analysis indicates that the use of bone drill increases the average time taken to operate. However, using a bone drill does not significantly improve the success rate of DCR. Stenting, on the other hand, was found effective for immediate improvement in the symptom recurrence, but the effect was not long term and the patient might require revision surgery.
