Intubation and stenting Some clinicians believe that partial stenosis of the<unk> <unk>  with symptomatic epiphora sometimes responds to surgical intubation of the entire lacrimal drainage system. This procedure should be performed only if the tubes can be passed easily. In complete<unk> , intubation alone is not effective, and a dacryocystorhinostomy should be considered. Dacryocystorhinostomy A dacryocystorhinostomy is the treatment of choice for most patients with acquired<unk> . Surgical indications include recurrent dacryocystitis, chronic mucoid reflux, painful distension of the lacrimal sac, and bothersome epiphora. For patients with dacryocystitis, active infection should be cleared, if possible, before a dacryocystorhinostomy is performed.
