Abstract Details


We compared to surgery success and reliability in patients performed transcanalicular Multidiode laser dacryocystorhinostomy (TCDCR) and external dacryocystorhinostomy (External DCR) with nasolacrimal duct obstruction.


Clinics of Ophthalmology, Istanbul Training and Research Hospital, Istanbul/Turkey


We performed TCDCR to 73 eyes of 64 patients with dacryostenosis in our clinic. External DCR performed with Dupuy-Dutemps-Bourguet technique to 107 eyes of 121 patients. Excluded criteria ; pediatric age group, recurrence cases, cases with adhesions in the sac dacryocystography, common canalicular stenosis, canalicular stenosis, neoplasms and dacryolith (s) of the lacrimal sac. Bicanalicular silicone intubation stenting was performed. Mitomycin-C was not used . Silicone stents were removed after 2 months postoperatively. Epiphora were evaluated with Munk scores. We considered successful to cases with Munk score of 0-1 and patency lacrimal irrigation.


: The mean age of the patients 56.7 ±14.3 years (37-76 years) and mean follow-up period was 14.2 ±2.2 months (range, 6-24 months) in TCDCR group. The mean age of the patients 59.6 ±13 years (35-74years) and the mean follow-up period was 18.3 ±2.3 months (range, 6-32 months) in external DCR group. Success rate 91.8% ( n= 67) in TCDCR group and 93.4% (n = 113) external DCR group. Achievement between the two groups was not statistically significant (p = 0.675).


External DCR is defined as the gold standard technique. TCDCR is an alternative technique in selected cases because high success rate of, low morbidity, shorter operative time, absence of any skin scar.
