Objective/Purpose
To compare the success rate of external Dacryocystorhinostomy (DCR) between suturing both flap (anterior and posterior) and anterior flap alone without intubation.

Materials/Patients
A total of 135 consecutive subjects aged between 12 year to 60 year having acquired nasolacrimal duct obstruction, between the period of December 2009 and November 2011, were enrolled.

Methods
All subjects underwent external DCR under local anesthesia without intubation. Subjects were randomized to have both flap DCR (group A) and anterior flap DCR with excision of posterior flap (group B). Subjects with canalicular disease and failed previous DCR were excluded. Postoperative subjective (epiphora) and objective (patency of passage by syringing) findings and complications were collected for analysis on day7, 1month, 3month 6month and 12month. Success was defined as significant relief of epiphora and patent passage at 12month visit.

Results and Conclusion
Group A consisted of 70 subjects (41 female and 29 male) and group B had 65 subjects (39 female and 26 male). One subject from group A and 2 subjects from group B lost follow-up and excluded from analysis. Sixty seven subjects out of 69 in group A and 61 subjects out of 63 in group B revealed significant relief of epiphora and patent passage at final visit. Success rate in group A was 97.1% and that of group B was 96.83% (p>.05). The success rate between the two groups was not statistically significant. One subject in group A had nasal bleeding on 1st postoperative day and was resolved with nasal pack. One subject from each group complained of visible scar.

The success rate of external DCR for acquired NLDO in adult seems to be similar with both flap suturing and suturing anterior flap alone without serious complication.
