Supiyaphun P Nasolacrimal duct injury is a well established complication of functional endoscopic sinus
surgery. In 1992, Bolger reported an incidence of nasolacrimal duct injuries in endoscopic sinus
surgery of up to 15 per cent, but there is no documentation in microscopic sinus surgery0
l.
Fluo-
rescein instillation into the lacrimal system
via
the punctum was done to determine the inci-
dence of nasolacrimal duct injuries in 16 patients who underwent 32 microscopic sinus proce-
dures. Only one patient exhibited nasolacrimal duct injury intraoperatively on the left side
(0.3%). He had complete healing of the nasolacrimal duct at 2 months and no postoperative
epiphora developed.
