A novel technique to recanalize the nasolacrimal duct with endodiathermy bipolar probe

Abstract

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). 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.
