[Conjunctivocystorhinostomy--seven years of experience--part I (Description of the surgery, groups of patients)].

The principle of conjunctivocystorhinostomy according to Jones consists in creating new way (tunnel) between the conjunctival sac and the nasal cavity where the drainage of tears is possible through a hollow tube made from allogenic material implanted into the tunnel. The main indication for performing the conjunctivocystorhinostomy is the obliteration of the proximal part of both lacrimal canaliculi. The operation consists of two parts--dacryorhinostomy (DCR) and the insertion of the draining tube. DCR may be performed from an external access, or from an endonasal access, which is preferred by the authors. Authors present altogether 74 surgeries, which were performed during the period of 1996-2002 in 59 patients, (55 women, 19 men) mostly in the group of 51-60 years of age. During the surgery, they use the glass tubes only, because, in contrast to the silicone ones, they become not to be obstructed. In 11 cases the loss of the tubing occurred. To prevent the possibility of the loss and the migration of the tube, the authors fixate it always with a stitch to the lower eyelid.
