Aim: To describe a new and simple bicanalicular silicone intubation technique, which can be used during dacryocystorhinostomy (DCR) surgery. Method: In this method, a lacrimal canula is used to pass the silicone tube through the lacrimal canaliculi. A 26-Gauge curved lacrimal canula is inserted into one end of a silicone tube with an inner diameter of 0.50 mm and outer diameter of 0.94 mm. The lacrimal puncta are enlarged using a one-snip procedure. The canula is introduced together with the

The other canaliculus is intubated in a similar manner. The tubes are passed out through the rhinostomy site and nose, and tied inside the nose. (revision DCR in 13 eyes, primary DCR in 10 eyes, canalicular DCR in 7 eyes, and endonasal DCR in 2 eyes) using the described method. No significant difficulty was encountered in any case. During the follow-up, a slit punctum developed in 1 eye and prolapsus of the tube at the medial canthus in another eye; no other complication was observed. Result: Silicone intubation was performed in 32 DCR procedures in 30 patients Conclusion: This method eliminates the need for retrieval of a metal leader from the lacrimal canaliculi and rhinostomy site and facilitates silicone intubation during DCR. It is a relatively nontraumatic and inexpensive method that may be an alternative to the other intubation methods.
