Aims: To determine factors associated and management of functional failure after Dacryocystorhinostomy among patients attending the eye department at KCMC hospital Moshi Kilimanjaro, from January 2007 to July 2018.

Study Design: A retrospective cross-section hospital-based study.

Place and Duration of Study: Conducted at Eye Department Kilimanjaro Christian Medical Centre Hospital, between August 2018 and August 2019.

Methodology: We recruited 184 patients who underwent external DCR surgery from January 2007 to July 2018. The analysis was done using STATA version 14. Chi-square was used to establish the difference in proportions across groups, multivariable logistic regression models were used to determine the associated factors for functional failure. The 95% confidence intervals were constructed; associations were considered to be statistically significant when a P-value was less than 0.05.

Results: Out of 184 external DCR done, 37 (20.1%) had functional failure, 174 (94.6%) attained anatomical success while147 (79.9%) attained functional success. Fifty-one (27.4%) of cases had a primary function failure, of this 50% was managed by probing and irrigation. Functional failure was associated with postoperative complications (AOR=10.58 (95% CI: 2.24 - 49.88).

Conclusion: Functional failure after external Dacryocystorhinostomy was 20.1%, the anatomical success of external DCR was 94.6% and functional success was 79.9% in our study. The strongest associated factors for functional failure were a post-operative complication and increased age. Therefore, careful post-operative follow-up after DCR procedure should be emphasized to lacrimal surgeons. On the other hand, external DCR remains the surgical management options with good success.
