Results of endoscopic endonasal dacryocystorhinostomy: A prospective cohort study

Abstract

Objective: To evaluate the success rate of endoscopic endonasal dacryocystorhinostomy. Method: The prospective cohort study was conducted at the Ophthalmology and Otorhinolaryngology departments, Shifa Foundation Community Health Centre, Islamabad, Pakistan, from October 2017 to September 2019, and comprised chronic dacryocystitis patients who underwent endoscopic endonasal dacryocystorhinostomy. Endoscopic dacryocystorhinostomy with or without lacrimal intubation was performed under general anaesthesia. The patients were followed up post-operative at 1 week, 1 month, 6 months and 12 months. Data was analysed using SPSS 20. Results: Of the 47 patients, 41(87.2%) were females. The overall mean age was 40.70±10.84 years (range: 25-66 years). Lacrimal intubation was performed in 31(66%) patients. Surgical success was achieved in 46(97.9%) patients. Of them, 37(78.7%) patients were completely symptom-free, while 9(19.1%) were partially symptomatic and were managed conservatively. Treatment failure requiring repeat surgical procedure was the case with 1(2.1%) patient. Procedure failure was more likely in patients with previous attacks of acute dacryocystitis (p=0.003). Conclusion: Endoscopic dacryocystorhinostomy was found to be a safe procedure with good anatomical and functional outcomes in chronic dacryocystitis patients.
