Abstract

Objectives To evaluate the role of ologen implant with silicon tube implantation in dacryocystorhinostomy (DCR) surgery regarding the success rate. Background External DCR is the treatment option for most cases of lacrimal drainage obstruction, including distal canalicular obstruction, common canalicular obstruction, and nasolacrimal duct obstruction. Patients and methods This prospective comparative case–control study was carried out on 30 patients attending the Ophthalmology Department, Menoufia University Hospitals. Patients included were those with primary acquired nasolacrimal duct obstruction with a positive regurge test. Patients were randomly enrolled into two groups using the alternating choice technique. Group A included 15 patients who had DCR surgery to treat the obstruction with silicone tubes and ologen implants. Group B included 15 patients who had a DCR with silicone tubes only. Results Success rates regarding relief of symptomatic epiphora were 86.6% in group A and 93.3% in group B, and the time of dye disappearance test was 3.9 ± 1.033 min in group A and 3.87 ± 0.640 min in group B, with P values of 0.598 and 0.833, respectively. Apart from immediate mild postoperative hemorrhage that was encountered in two cases in group A and one case in group B, there were no significant complications in both groups. Conclusion This study shows that the application of ologen implants in external DCR surgeries may improve symptomatic epiphora without exposing the patients to more intraoperative or postoperative complications. However, the follow-up period was relatively short and the sample size is relatively small, and further work is required to verify the effect of ologen alone in external DCR surgeries.
