Does the timing of silicone tube removal following external dacryocystorhinostomy affect patients' symptoms?
OBJECTIVE
To investigate whether the timing of silicone tube removal after external dacryocystorhinostomy (EXT-DCR) for lacrimal outflow obstruction affects outcome.


METHODS
Retrospective chart review and follow-up by telephone survey of 205 consecutive patients undergoing EXT- DCR. Long-term success was evaluated by telephone survey.


RESULTS
Full data was collected in 180 out of 205 DCRs. Ninety four tubes (52.3%) were removed routinely between 2 and 4 months after surgery, 24 tubes (13.3%) were removed before the planned 2-month period and 62 tubes (34.4%) were removed after the planned 4-month period. The three groups (early, routine and late) were comparable in terms of age, gender distribution, mode of anaesthesia, proportion of repeat EXT-DCRs and seniority of surgeon. The mean follow-up period was 3 years and 10 months. One hundred and twenty-eight of the 155 patients (82.5%) were contactable by phone. In the routine tube removal group, at the time of follow-up, 65.1% experienced complete symptom resolution, 25.4% experienced partial symptom resolution, 6.3% experienced no symptom resolution and 3.2% experienced worse symptoms. In the early tube removal group, at the time of follow-up, 63% experienced complete symptom resolution, 32% experienced partial symptom resolution and 5% experienced no change in symptoms. In the late tube removal group, at the time of follow-up, 70% experienced complete symptom resolution, 21.5% experienced partial symptom resolution and 8.5% experienced no symptom resolution. There was no statistically significant difference in the outcome of the three groups.


CONCLUSIONS
Our experience and this study suggest that timing of silicone tube removal does not influence surgical success in EXT-DCR regardless of the cause of early or late tube removal.
