The fact that so many different surgical procedures in chronic nasolacrimal duct obstruction are in use, shows that we still do not have for this pathology a reliable surgical technique.

The endonasal dacryocystorhinostomy (endoDCR) is a scar-free surgery, but it has to be underlined that several different surgical procedures can be used: laser, non laser, endoscopic, microscopic, with or without stent.

We perform the endoDCR by an operative microscope, without laser and with a bicanalicular silicone stent implant.

This kind of endoDCR technique seems to be very useful particularly when acute dacryocystitis occurs, both because:

  • the pus accumulated can be easily drained from the lacrimal sac avoiding the arise of major complications such as orbital cellulitis and the lacrimal sac perforation, and
  • the impossibility to access to the lacrimal sac via the lacrimal puncta, due to the Rosenmuller valve occlusion.
