BACKGROUND/AIMS
Endonasal laser
dacryocystorhinostomy (ELDCR) has many potential advantages over
conventional external DCR. Although the short term results of this
technique have been reported, little is yet known of the long term
results, and the occurrence of late rhinostomy failure. The aim of this
study was to examine the results at 3 and 12 months following ELDCR.
METHODThe notes of all consecutive ELDCRs
performed between November 1993 and May 1995 were retrieved.
Demographic information, details of surgery, and the postoperative
results were noted.
RESULTSELDCR procedures which did not undergo
lacrimal stenting showed a short term success rate of 67% at 3 months,
and a further failure rate of 9% at 12 months. ELDCRs which did
undergo lacrimal stenting showed a short term success rate of 82% at 3 months, and a further failure rate of 21% at 12 months. Lacrimal
intubation increased the long term success rate by 8%. The success
rate was lower in the presence of local risk factors for nasal mucosal scarring.
CONCLUSIONSELDCR requires some adjunctive
treatment to improve maintenance of the nasal mucosal ostia if it is to
compete successfully with external DCR on grounds other than cosmesis
and patient convenience.
