Endoscopic dacryocystorhinostomy and retrograde nasolacrimal duct dilatation with cannulation: our experience.

Endoscopic endonasal dacryocystorhinostomy [EDCR] is considered to be a superior alternative technique to the conventional external dacryocystorhinostomy [DCR], both in primary and secondary cases. It is of particular value in children and young adults as it avoids an external scar. Sixteen cases of chronic dacryo-cystitis were treated by the endoscopic technique, including 8 revision cases of failed external approach. In all cases except one, a patent nasolacrimal fistula was noted, with a success rate of 93.7%. The authors share their experience in EDCR and review the relevant literature.
