Summary:
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.DCRmay be performed froman 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.
