Dacryocystorhinostomies fail in a large percentage of cases because of obstruction of the newly made canal by granulation tissue and scar contracture. A tapered silicone sponge implant * has been used in 12 successive operations for chronic dacryocystitis without failure (Fig 1).
The purpose of this communication is to demonstrate the use of this material. The operative technique was a modification of the Dupuy-Dutemps procedure.† All operations were performed under local anesthesia.
After the bony opening is made, an H-shaped incision is made into the mucous membrane of the nose to create anterior and posterior flaps. A similar incision is then made in the lacrimal sac after putting it on the stretch with a Bowman probe inserted through the lower canaliculus. The posterior flap of the sac is now sutured to the posterior flap of the H-incision of the nasal mucosa using small curved Davis and Geck No. Cl needles with
