[Results of the modified dacryocystorhinostomie described by Werb (author's transl)]

42 cases operated by the modified Werb's dacryocystorhinostomy with polyethylene tubing are reported. The postoperative follow-up was between 1 and 4 1/2 years. The success rate was 75%. The tube should remain at least 3-4 months. A longer time does not give significantly better results. On 2 unsuccessfully operated persons strong fibrous scar tissue was found during the reoperation at the site of the anastomosis of the tear sack with the nasal mucous membrane. This was probably induced by remaining bone fragments. This simple operative approach can be recommended as a first surgical intervention on patients with a presaccal tear duct stenosis.
