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 diagnostic contribution of the radiological investigation in patients with persistent or recurrent symptoms. In patients whose symptoms were referable to the operated side, dacryocystography was performed as part of further pre-operative assessment. In 42% of these patients it demonstrated an anatomical or physiological abnormality that explained the symptoms. However, no clear reason for the recurrence of symptoms was demonstrated in 58% of cases.
