OBJECTIVE This study aimed to compare the outcomes and efficacy of canalicular trephination with monocanalicular stenting and canaliculodacryocystorhinostomy (canaliculoDCR) with silicone intubation. METHODS A prospective comparative study was done in 30 patients (30 eyes) with common canalicular blocks who were randomized into two groups. Fifteen patients underwent canalicular trephination with monocanalicular stenting and 15 patients underwent canaliculoDCR with silicone intubation. Common canalicular obstruction was diagnosed by preoperative syringing and the location of block was confirmed on probing. Stents were kept in both the groups for 3 months and followed up till 6 months postoperatively. Success was defined based on both anatomical and functional outcomes. Anatomical success was defined by the free passage of fluid on syringing with the fluid felt in the throat. Functional success was defined in terms of relief from epiphora based on the subjective opinion and its categorization by Kraft and Crawford's grading and the fluorescein dye disappearance test (FDDT). RESULTS Eighty percent of eyes in canalicular trephination group and 73.3% of eyes in canaliculoDCR group were anatomically patent on syringing at the final follow-up. Sixty-six percent of eyes in trephination group and 53.3% in canaliculoDCR group were reported to have absent epiphora (complete recovery). Ten eyes in both groups had Grade 0 and 1 FDDT indicating a functional success of 66.6% in both groups. CONCLUSIONS Canalicular trephination can produce results comparable to canaliculoDCR with silicone intubation in cases of common canalicular blocks. The average duration of surgery is significantly less in canalicular trephination which gives this procedure an added advantage.
