چکیده

To compare the surgical duration and clinical outcomes of nasolacrimal recanalization versus external dacryocystorhinostomy (DCR) in the treatment of failed nasolacrimal duct intubation.This is a retrospective, comparative, and interventional study. We evaluated the outcomes of 66 consecutive patients undergoing either nasolacrimal recanalization (n = 32) or DCR (n = 34) in a tertiary lacrimal disease referral center. Length of surgical duration, clinical outcomes, and rate of recurrence at 18 months postoperatively were compared.The mean surgical duration was 18.5 minutes (range, 15-25 minutes) for nasolacrimal recanalization and 48.2 minutes (range, 45-61 minutes) for DCR, respectively (P < 0.001). The rate of success was 84.4% in the recanalization group and 85.3% in the DCR group, respectively (P = 0.91). The time to recurrence was 2.6 ± 1.1 months in the recanalization group and 5.6 ± 2.1 months in the DCR group (P < 0.001). Five failed cases in each group received a secondary DCR surgery with the same resolution rate (40%). The absence of ocular discharge at baseline was a significant predictor for a successful outcome in the recanalization group (P = 0.04) but not in the DCR group (P = 0.63).Nasolacrimal recanalization is an effective, safe, and time-saving alternative to DCR for the treatment of failed nasolacrimal duct intubation. Clinicians should be cautious in patients with discharge.

Silicone Intubation Indications in External Dacryocystorhinostomy

External dacryocystorhinostomy (DCR) is the gold standard surgical technique for the treatment of nasolacrimal duct obstruction (1). Since its introduction by Gibbs in 1967, intubation with silicone tubes has been widely used in lacrimal duct surgery (2). However, effect of silicone intubation on patency of lacrimal system during external DCR in cases of primary nasolacrimal duct obstruction (N...

Monocanalicular versus bicanalicular intubation in external dacryocystorhinostomy for primary acquired nasolacrimal duct obstruction.

PURPOSE Monocanalicular intubation offers potential advantages over bicanalicular intubation including ease of removal and use of only one canaliculus. Recent reports suggest equal outcomes with both types of tubes for nasolacrimal intubation. This study aimed to evaluate the outcome of monocanalicular intubation during external dacryocystorhinostomy. METHODS Fifty-seven lacrimal systems of 5...

Long-term outcomes after transcanalicular laser dacryocystorhinostomy

The main objective of the present study was to prospectively evaluate long-term surgical success and safety in patients with nasolacrimal duct obstruction treated with a multidiode transcanalicular laser and bicanalicular silicone intubation stenting. 42 patients treated with transcanalicular laser dacryocystorhinostomy for nasolacrimal duct obstruction were prospectively enrolled. In all cases...

Transcanalicular Diode Laser-assisted Dacryocystorhinostomy for the Treatment of Primary Acquired Nasolacrimal Duct Obstruction.

Today's gold standard in the treatment of infrasaccal primary acquired nasolacrimal duct obstruction (PANDO) is external dacryocystorhinostomy (DCR), a relatively invasive procedure that can be performed after failure of recanalizing treatments. However, with progress in the field of diode laser technology, new approaches have emerged. Laser-assisted transcanalicular DCR with subsequent bicanal...
