[Initial experience with the Jones method of conjunctivo(dacryo)cystorhinostomy].
In obstruction of both lacrimal ducts at present the most frequently used method is conjunctivo(dacryo)cystorhinostomy using a Jones bypass cannula. The effectiveness of the procedure is 85-90%. The drainage cannulas can be straight or bent and are as a rule made from pyrex glass. The patients should be highly motivated and made familiar with possible complications, i.e. most frequently escape of the cannula. With regard to the necessary postoperative cooperation the operation is not recommended in young children. The authors performed in 1996-1997 a total of 8 conjunctivo(dacryo)cystorhinotomies. The lacrimal sac is opened into the nose under general anaesthesia by the endonasal route using endoscopes. In one instance the authors used a straight silicone cannula which fell out after three weeks. In the remaining patients they used a bent silicone cannula. Seven patients evaluate their condition after surgery as markedly improved and would be willing to have the operation again. One female patient (after escape of a straight cannula and later reinsertion of a bent cannula) would hesitate to have another operation. The authors evaluate their experience with this type of bypass operation as very satisfactory.
