title: [Falk's lacrimal sac surgical technique for stenosis (author's transl)].
abstract: The lacrimal sac as such is sacrificed in Falk's extra-nasal dacrocystorhinostomy. It is opened along its entire extent and embedded in toto into the lateral nasal wall. This procedure proved to be successful in most kinds of lacrimal duct stenosis. Its indications have now been extended to include those with obliteration of the lacrimal canaliculi and where the sac is itself obliterated. In such cases a thin silicone tube passed into the lower lacrimal punctum through the inferion lacrimal canaliculus and into the nose.
