由于泪总管狭窄而形成的泪溢,相当常见,以往的修复方法,操作困难,且结果不尽良好。新近采用合成塑料橡皮管(silastie)以使狭窄的泪总管保持通畅,手术操作简易,效果满意。取5～6毫米长的合成塑料橡皮管(0.040″×0.090″),围绕其管周,用医用胶(vivosil)作两个小结节,此二结节相距3～4毫米。此管于术前24小时 Tears due to the narrowing of the common sores of the lacrimal duct are quite common and the previous methods of repair have been difficult to handle and the results have not been satisfactory.
