—I was interested to read the article by Massaro et al1 in the August 1990 issue of the Archives describing the new approach to dacryocystorhinostomy (DCR) by using an endonasal laser technique. They are to be commended for the creative way that they have applied modern technology to an old procedure. The endonasal laser DCR procedure that they described causes a discrete fistula, avoids a scar, provides hemostasis, and improves the postoperative comfort of the patient. With their technique, a 20-gauge fiberoptic light pipe is passed through the canaliculus into the medial lacrimal sac. Using a nasal endoscope, the transilluminated area is then treated with an argon laser that is delivered through a 300-μm quartz fiberoptic laser catheter. Gonnering et al2 have since described another 18 patients who underwent a similar procedure, five using the carbondioxide laser and 13 patients using the potassium titanyl phosphate
