Abstract

PURPOSE
To evaluate the causes of failed dacryocystorhinostomy (DCR) and the effects of transcanalicular diode laser-assisted endonasal revision surgery according to the number of silicone tubes.
METHODS
Sixty-seven patients (70 eyes) who underwent revision surgery using transcanalicular diode laser for failed primary endonasal DCR at Sungmo Eye Hospital between March 2007 and December 2012 were studied retrospectively. The causes of failed DCR and the time of recurrence were evaluated. The revision surgeries were endoscopic removal of granuloma and membrane and synechiolysis with intubation of 1 or 2 silicone tubes. We compared the results of revision surgery with 1 silicone tube and 2 silicone tube intubations.
RESULTS
Recurrence occurred after a mean duration of 4.6 months following the first DCR. The causes of surgical failure were granuloma (35 eyes), membranous obstruction (23 eyes), synechia (7 eyes), and functional obstruction (5 eyes). We performed revision surgery with 1 silicone tube intubation in 45 eyes (group A) and 2 silicone tube intubations in 25 eyes (group B). The final success rates in groups A and B were 75.6% (34/45) and 84% (21/25), respectively (chi-square test, p = 0.828).
CONCLUSIONS
Transcanalicular diode laser-assisted endonasal revision surgery with 2 silicone tubes is not recommended.
