Background: Epiphoracan be extremely troublesome and a source of social embarrassment. There are various methods of performing dacryocystorhinostomy for the treatment of nasolacrimal duct obstruction. Present study is planned to evaluate the results of Endoscopic Endonasal DCR without silicon stent in patients with nasolacrimal duct obstruction at tertiary level health care center.
Materials & Methods: A hospital based prospective study done on 40 patients diagnosed as nasolacrimal duct obstruction or chronic dacryocystitis at department of ENT, at RVRS Medical College, Bhilwara Rajasthan, India during one year period.Patients were divided into two groups:Group I for Endonasal Endoscopic DCRwithout silicone stent (N=20)and Group II for conventional (external) DCR (N=20).Nasolacrimal Duct Obstruction Symptom Score (NLDO-SS) questionnaire was given and symptom score were calculated.Lacrimal syringing was performed in all the cases.Subsequent follow up done post-operatively at fourweek, 12 week & 6 month.
Results: The mean age was 45.51±11.43 years (range 15 to 77 years). The demographic variables such as age, sex, laterality, associated nasal pathology and additional procedure was statistically non significant. The mean surgical duration in group I was 40.23±9.45 minutes & in group II was 41.2±8.76 minutes, which was statistical non significant (P>0.05).The success rate of En DCR is 95%. Complete objective & symptomatic relief was seen in 19 (95%) cases, & 1(5%) reported no symptomatic relief after one month and 90% success rate after 6 month in both groups.
Conclusion: We concluded that endonasal DCR is a procedure that has recently gained by otorhinolaryngologists due to its minimal invasive nature, high patient satisfaction, and high success rates.
