Background and Objectives: External DCR is an
effective and common surgical approach in treating nasolacrimal duct
obstruction. To investigate the relation between the times of silicone
tube removal after external dacryocystorhinostomy, related factors
and success rate of surgery. Method: In a retrospective study, 168 patients with
primary nasolacrimal duct obstruction (NLDO) which underwent
dacryocystorhinostomy (DCR) with intubation were evaluated. Demographic
information including age, gender, time of silicone tube remaining in the NLD,
follow up period and result of the operation were recorded. The result of
the surgery in first group (patients with tubes being lost before the planned
time) and second group (patients with tubes being removed after the planned
time) were extracted and compared. Failure of surgery was defined as
symptomatic epiphoria or infection in follow up period. Results: From 168
patients with complete follow up in17 cases tube was extruded or
had to be removed before planned 3 month period. Success rate was 82.3% in
first group and 92.1% in second group. There was no significant difference
statistically between two groups (P=0.18). 3 people the mentioned 17 patients
who were lost their tube earlier had undergone reoperation. Conclusion:
This study shows that the time of silicone tube removal has no effect on
success rate of surgery. Endoscopic evaluation of osteotomy site regarding
obstruction occurrence are suggested to estimate the appropriate time of
silicone tube removal.
