[Value of external dacryocystorhinostomy].
Present surgical techniques to distal obstruction of the nasolacrimal duct system are the external dacryocystorhinostomy (DCR) and alternatively the endonasal laser-assisted DCR and the transcanalicular laser-assisted DCR. Combining the own experiences and the overview of bibliography the different surgical techniques are compared. As criteria are used the success rate (long term patency rate), the perioperative conditions and the patient selection. The conclusion is that the success rates for conventional external lacrimal surgery are better than those for endonasal and transcanalicular laser-assisted DCR. Therefore at present the external DCR still remains the gold standard by which other methods are measured.
