title: [Endonasal dacryorhinocystostomy].
abstract: Endonasal dacryorhinocystostomy is a surgical procedure performed to re-establish continuity of the lacrimal duct by partial diversion followed by dilatation. A simultaneous rhinologic and ophthalmologic approach is used. This simple and elegant procedure that results in no residual scarring is indicated for any blockage of the lacrimal duct due to congenital or acquired causes. Except for children under 6 years of age and in patients in poor general condition, contra-indications are uncommon. Operative and postoperative complications are rare. After a review of the relevant anatomy the authors of this report describe the equipment and basic techniques used to perform dacryorhinocystostomy. Endonasal dacryorhinocystostomy was performed in 15 patients presenting chronic (n = 14) or acute (n = 1) dacryocystitis in Madagascar. At six months follow-up the procedure was successful in 14 cases and unsuccessful in one case due a cutaneous fistula. Because it is simple and well-tolerated and results in no residual scarring, endonasal dacryorhinocystostomy is the method of choice for treatment of lacrimal duct obstruction in tropical areas in general and in Black Africa in particular.
