    Abstract:
    Here we describe a modified preserved nasal and lacrimal mucosal flap technique in endonasal endoscopic dacryocystorhinostomy (EES-DCR) for patients with epiphora secondary to primary acquired nasolacrimal duct obstruction (PANDO) and evaluate its outcomes. Twenty-five patients with PANDO were retrospectively reviewed. Modified preserved nasal and lacrimal mucosal flap technique in EES-DCR was applied in all 27 eyes of 25 patients. The patients were evaluated with objective (anatomical patency) and subjective (symptomatic cure) success rates within the duration of follow-up. In the present study, all of the patients' surgical procedures were successful. There were 2 cases of flap dislocation from the rhinostomy site 1 week post-operation. After a mean follow-up of 4.9 ± 1.8 months, the success rate of anatomical patency was 100% (27/27) and the success rate of symptomatic cure was 92.6% (25/27). No significant complications occurred intraoperatively. We concluded that the modified preserved nasal and lacrimal mucosal flap technique in EES-DCR for treating PANDO is simple and safe, can effectively cover the bare bone around the opened sac, and provide a similar or even better clinical outcome compared with other routine treatment techniques used for this condition.
