Title | Time will tell: Risk for second contralateral DCR in the future |
Abstract Nr. | 1049 |
Purpose | To investigate retrospectively a population of patients that underwent a dacryocystorhinostomy (DCR) for nasolacrimal duct obstruction between 2002 and 2010 the percentage of bilateral operations, and evaluate the time-lapse between the first DCR and the second contralateral DCR, both in primary and secondary nasal duct obstruction. |
Methods | retrospective study, with evaluation of status and questionnaire for general practitioners. |
Results | 794 DCR patients were identified of which 704 with a primary acquired nasolacrimal duct obstruction (PANDO) and 90 secondary nasolacrimal duct obstructions (SANDO). Most secondary obstructions occurred after nasal operationos (n= 43) or in trauma patients (n=22). Of the 704 PANDO patients 146 (20.5%) were operated bilateraly at presentation. Of the 557 unilateraly operated patients, 74 were operated on the contralateral side, with a mean time between the sides of 8 years (range 6 months and 46 years). Of the 90 SANDO patients, 9 were operated on the contralateral side in a second procedure. |
Conclusion | In 13% of patients with a PANDO that were operated unilateraly, an obstruction occurred within 8 years after the first operation. Contralateral nasolacrimal duct obstructions can occur very late, up to 46 years after the first operation. |
