Introduction: Tearing and recurrent chronic conjunctival discharge are the most frequent
symptoms and signs of lacrimal pathway obstruction.Because conservative care is usually
ineffective in chronic conditions, the definitive treatment for the condition is surgery in which
the patency of the nasolacrimal pathway is restored. A dacryocystorhinostomy (DCR) is the
creation of a fistula from the lacrimal sac into the nose. Present study is planned to evaluate
the results of Endoscopic Endonasal DCR with or without silicon stent in patients with
nasolacrimal duct obstruction at tertiary level health care center.
Materials and Method: The present study was conducted among 60 cases that were
diagnosed as nasolacrimal duct obstruction or chronic dacryocystitis. The study population
was divided in three groups i.e., group I for endonasal endoscopic dacryocystorhinostomy
with silicon stent, group II for endonasal endoscopic dacryocystorhinostomy without silicon
stent and group III for conventional (external) DCR.Differences between the two groups were
assessed with the Pearson ChiSquare and Fisher’s exact test and differences were regarded as
statistically significant if a two-sided P-value was less than 0.05. Data are expressed as the
number of cases or mean with standard deviation (SD).
Results: The maximum number of patients 27 cases (45%) was in the age group of 41-50,
followed by 12 cases (20%) in the age group of 51-60. Group I had a mean age of 43.4 years,
range 15–77 years, and Group II had a mean age of 45.7 years, range 24–72 years. The two
groups were comparable in age wise distribution.We found intra operative bleeding was more
in conventional DCR in Group III 10 cases (50%) has more bleeding while in Group I, 2 case
(10%) and Group II 2 case (10%) has more bleeding. Though the success rate of Group I was
(95%) better than Group II (90%), and in Group III success rate is also (90%) it was not statistically

Conclusion: The present study concluded that a statistically significant difference was found
between the preoperative and one-week postoperative. Though the success rate of Group I was
(95%) better than Group II (90%), and Group III (90%) it was not statistically significant.
Furthermore, a longer follow-up time may give more reliable objective outcome information.
