We call endonasal dacryocystorhinostomy to the surgical technique that has as purpose the treatment of the obstruction of the lacrimal system, through the nasal cavity, approaching it with the help of an optical microscope, surgical endoscopes or laser. In the surgical act the obstructed lacrimal route is communicated with the corresponding nostril, to improve the evacuation of tears. In many cases, a probe is placed in the tear line to try to ensure the permeability of the new orifice. This probe is maintained for a very variable time, which can reach several months, and will be withdrawn depending on the criteria of the surgeon and the evolution of the cicatricial process.
