Revision endoscopic dacryocystorhinostomy

Dacryocystorhinostomy (DCR) failures may occur after primary external or endoscopic approaches. Revision surgery is beneficial for many of these patients. Clinical experience suggests that endoscopic lacrimal surgery offers technical benefits over the traditional external approach that may aid in revision cases. Ultimately, the operative goals of revision endoscopic DCR are similar to that of primary surgery. Advancements in endoscopic technology and instrumentation have been helpful in achieving these procedural goals. This article describes the authors' rationale and technique for revision endoscopic DCR.
