【 摘 要 】

Aims: To evaluate a new approach for recanalization (RC) of nasolacrimal duct obstruction in the treatment of the symptomatic nasolacrimal duct obstruction (NLDO). Materials and Methods: A prospective, interventional, comparative study in 302 eyes of 209 patients of symptomatic nontraumatic NLDO. Eyes with previous failed surgery were excluded. One hundred and fifty-one eyes underwent RC with 20 G endodiathermy bipolar probe connected to a 7 W diathermy followed by bicanalicular intubation under direct visualization. One hundred and fifty-one eyes underwent standard external dacryocystorhinostomy (DCR). Follow-up was for 24 months and evaluation was done on basis of change in symptoms and lacrimal syringing. Data was analyzed by Chi-square test and unpaired t-test. P value < 0.05 was considered statistically significant. Results: Success defined as an asymptomatic patient or freely patent syringing was 92.7% (140 eyes) in RC group and 83.44% (126 eyes) in DCR group. Success was significantly more (P ≤ 0.01) in RC than DCR group. Surgical time was significantly less in RC than DCR (P ≤ 0.001). In RC group, RC could not be performed in three eyes and had to be later taken up for DCR. Intubation after RC was not achieved in four eyes; however these eyes had a patent pathway till 24 months. Twenty-two eyes had a premature extrusion of the tube; but the success rate in these (20 eyes) was comparable to the others within the group (P > 0.05). Two eyes in RC and one in DCR group had complications. Conclusions: RC with 20 G endodiathermy bipolar probe is a quick, simple, and effective alternative to standard external DCR.
