title: [Dacryocystorhinostomy using Nd YAG laser by the intracanicular approach].
abstract: Endocanalicular dacryocystorhinostomy is a recent surgical procedure for stenosis of the naso-lacrymal duct, thanks to a laser filter fitted into the heart of 800 mu diameter metallic pin constituting a rigid armed laser probe. We create a lacrymo-nasal orifice from inside the lacrymal bag towards the nose, using the laser fiber. The Nd YAG used is the solid state mobilisable Ophtalas sp 32 giving out infrareds at 1064 nm or green at 532 nm. The indications are the stenosis of the naso-lacrymal duct, the failed classical dacryocystorhinostomy, the conjunctivodacryocystorhinostomy and the stenosis of the common canaliculus. This surgical procedure compared to the classical surgical technics appears to the very promising due to its simplicity, innocuousness, time saving. Our results, still inferior to the classical technique for all indications (success rate: 70%) are very good for the idiopathic stenosis of the naso-lacrymal duct (success rate: 87.5%).
