title: [Contributions to the surgical technique of external dacryocystorhinostomy (author's transl)].
abstract: The authors describe some modifications of the surgical technique of external dacryocystorhinostomy. The preliminary exploration methods and their evaluation are considered. An arched skin incision is used for a more anatomical dissection to approach the lacrimal sac. The following bone trepanation is then made with burrs designed by Burch Barraquer. It should be rather large (15-20 mm), backwards and downwards in the nose bone. A running suture, with three external skin stiches as pexia, is used to tie the anterior muco-mucosal flaps together. This suture is them removed after approximately 12 days. Management and procedures in special cases as well as in reoperations are also discussed.?Author
