This 59 year-old woman had had bilateral endonasal
dacryocystorhinostomy (DCR). She was symptom free for about 6 months but
returned to the clinic recently complaining of right epiphora. Syringing
revealed blockage in the right nasolacrimal system but patent in the left
system. A DCG was requested which revealed blockage of the right nasolacrimal
system. On the left side, the DCG demonstrated patent fistula between the
nasal cavity and the lacrimal sac.
She later underwent external DCR with good result. |
