A comparison of external and endonasal dacryocystorhinostomy in regard to patient satisfaction and cost.

Abstract

BACKGROUND: Definitive treatment of nasolacrimal duct obstruction is with external or endonasal dacryocystorhinostomy (DCR). Recent trials suggest surgical equivalency between techniques.
