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.
报告了42例行改良韦布氏泪囊鼻腔造口术并置入聚乙烯管的病例。术后随访时间为1至4年半。成功率为75%。置管应至少保留3至4个月。保留更长时间并不会显著改善效果。在2例手术未成功的患者再次手术时，在泪囊与鼻黏膜吻合处发现了致密的纤维瘢痕组织。这可能是由残留的骨碎片引起的。这种简单的手术方法可推荐作为泪囊前泪道狭窄患者的首次手术干预。
