title: Intranasal visualization for nasolacrimal duct intubation.
abstract: OBJECTIVE
  To improve intranasal visualization of nasolacrimal procedures we use a self-retaining nasal speculum with or without a sinuscope.
  
  
  CONCLUSIONS
  Placement and retrieval of silicone stents can be accomplished with less trauma than with a blind sweep technique. Additionally, the valve of Hasner can be seen and the creation of false passages avoided.
