► Congenital
fistula of lacrimal bag
► Double
lacrimal point
► Endoscopic
dacryocystorhinostomy (DCR) phase. Left lachrymal bag exposed after
the resection of the ascending apophysis of the maxillary. (30є
optics).
► Situation
during the healing of the proximal lachrymal via. Note that both ends
of the catether emerge from the same place, the common canaliculo
opening.
► Situation
once the endoscopic DCR (dacryocystorhinostomy) has finished. The
mucous flap of the lower base has been replaced without occluding the
neo-ostium of the lachrymal via. Below, part of the middle cornet head.
(30є optics).
► Catheter
location in lachrymal tract (annular catetherisation). The catether
does not touch the conjunctiva but at the same time permits opening of
the eyelids. The catether remains from 3 to 4 weeks. (0є optics).
► Cicatrisation
phase after a left endoscopic DCR (dacryocystorhinostomy) at
approximately 2.5 weeks. The side wall of the lachrymal tract is seen
and the catether emerging from the common canaliculo. (30є
optics).
► The
same patient after removing the catether at 4 weeks. Small
granulations on the medial edge. Start of application of topic
corticoid associated to rinses with physiological serum. The
application of a collyrium (with corticoid and antibiotic) as
artificial tears continues for several weeks more. (30є optics).
► The
same patient six months after endoscopic DCR (dacryocystorhinostomy).
Note the relation between the middle cornet head and the lachrymal bag
opening, above and posterior (30є optics).
► Cicatrisation
phase after a left endoscopic DCR (dacryocystorhinostomy) at about 4
weeks. Ideal time to remove the catether. (30 є optics).
► Annular
catetherisation probe after endoscopic DCR (dacryocystorhinostomy). (0є
optics).
