PURPOSE: To describe the technique of non-endoscopic endonasal dacryocystorhinostomy (NEN-DCR), and its indications and results.
MATERIALS AND METHODS: In a prospective, non-randomized interventional case series, all consecutive cases presenting with epiphora between 2004 and 2006 were enrolled. Adult patients were divided into three subgroups: chronic nasolacrimal duct obstruction (NLDO), NLDO with dacryocystitis (NLDO-DC), and recurrent NLDO with previous failed external DCR (REV-DCR). All procedures were performed by one surgeon (first author). An endonasal DCR was performed through a nasal speculum without the use of an endoscope. Success was measured by both improvement of the epiphora and patency of the lacrimal system during irrigation.
RESULTS: Ninety-five patients (24 men, 71 women) underwent 99 NENDCR procedures; 54% of cases had NLDO, 32% had NLDO-DC, and 14% were REV-DCR. Mean duration of surgery was 30 minutes, and the average amount of intraoperative bleeding was 12 ml. After a minimum follow-up of 6 months, success was achieved in 96% of all patients, 94% in the NLDO group, 97% in the NLDO-DC group, and 92% in the REV-DCR group. The failure rate was 4% overall. Two patients failed from the NLDO group, one patient from the NLDO-DC group, and one patient from the REV-DCR group. No significant late complications were detected.
CONCLUSION: The success rate of NEN-DCR compares favorably with external DCR. The technique is also useful in cases of NLDO-DC and DCR-REV.
