Treatment of the fistula associated with dacryocystitis without excision but removing only the source of infection by endoscopic dacryocystorhinostomy. Twelve cases of fistulae associated with dacryocystitis were collected. The idea not to remove the fistulae but to exice the underlying lesion. To accomplish this goal, all cases under general anesthesia were treated not with the classical way by excision but with intranasal endoscopic dacryocystorhinostomy associated with intubation. Healing of the fistulae occur within 10- 21 days. No need for classical surgical interference for treating a fistula if a profitable intranasal endoscopic dacryocystorhinostomy was realized.
