To present the anatomical and functional success rate of dacryocystorhinostomy (DCR) procedures done at a tertiary referral center in the UK between 2013 and 2017. Moreover, evaluate the use of intraoperative triamcinolone to improve the success rate.

The medical records of 293 patients who underwent external or endonasal DCR from January 2013 until January 2017 were retrospectively reviewed. Surgical and functional success rates were evaluated. Triamcinolone injection was used as adjunctive in selected cases where a high risk of failure was anticipated. Correlation between intraoperative triamcinolone use and success rate was evaluated. Possible adverse effects of triamcinolone were documented and indications for usage of triamcinolone were investigated.

314 cases from a total of 363 DCR’s were included in our study. Mean age was 62 years and mean duration of symptoms was 21 months.The mean follow up period was 10.53 months. Anatomical success rate was 93.9% although the functional success rate was 82.5%. Intraoperative triamcinolone was injected in nasal and lacrimal flaps in 51 patients. No adverse effects from the use of triamcinolone were noted to our cohort of patients. Regarding the patients that underwent surgery for NLDO or functional epiphora no statistical significance was found between use of triamcinolone and success rate however for the revisioanl endonasal operations the functional success rate was 50% with no use of triamcinolone increasing to 100% when triamcinolone was used.

Success rate of DCR in our study was comparable with national standards. Use of triamcinolone injection revealed a trend towards increase of success rates in redo endonasal DCR’s.
