The value of intubation dacryocystography after dacryocystorhinostomy

We retrospectively reviewed 104 dacryocystograms carried out on 72 patients who had previously undergone dacryocystorhinostomy, to assess the diagnost ic contribution of the radiological investigation in patients with persiste nt or recurrent symptoms. In patients whose symptoms were referable to the operated side, dacryocystography was performed as part of further pre-opera tive assessment. In 42% of these patients it demonstrated an anatomical or physiological abnormality that explained the symptoms. However, no clear re ason for the recurrence of symptoms was demonstrated in 58% of cases.
