[Localization of lacrimal drainage system obstruction by diaphanoscopy].
Endonasal dacryocystorhinostomy is the standard treatment for obstruction of the lacrimal drainage system. Localization of the stenosis can be difficult intraoperatively, especially in chronic sclerosing dacryocystitis or re-operations. We present a technique of intraoperative diaphanoscopic localization of the stenosis with the use of a special small light fiber that is inserting through the lacrimal points down to the stenosis. The lighted fiber illuminates the area, which has to be exposed endonasally and drain to the nose. This little addition contributes to a meticulous and straightforward operative technique.
