Paper Abstract

Intranasal Holmium:YAG laser dacryocystorhinostomy after failed external dacryocystorhinostomy were successfully performed in 6 patients. The inner wall of lacrymal sac is identified by the illumination of a fine fibroptic probe which is passed through the upper canaliculus and directed medially into the obstructed sac. The most bright spot as seen intranasally is marked as a target for laser penetration, using O.5-1J, 5-15w, 10-15 pulses/second. Through 400um quartz fiber delivery depending upon the consistency of the tissue. The new opening about 6mm in diameter is made with relative ease from inside of nasal cavity as the opening is only 40 42mm from the nostril. A silicone rod of 2 loops or 3 loops is introduced retrogradely into the lacrymal passage as a stent which should stay for 4 months or longer. Among the 6 patients, 5 cases were successful. The follow up period were 4-17 months after removal of silicone rods. One case was failed as the silicone rod was accidentally broken at 5 weeks after operation. The advantages of this operation are: avoidance of skin incision, deep sutures, bleeding and scarring.
