Endoscopic Primary DCR Part 1 of 2


  • Epiphora
  • Chronic dacryocystitis


  • The maxillary line is an important intranasal landmark for identification of the lacrimal sac
  • Endoscopic visualization of lacrimal probes passed by an assistant verifies that the lacrimal sac has been entered
  • Visualization of the internal common punctum ensures an adequate opening into lacrimal sac has been made
  • A Silastic stent is placed

Keep in Mind:

  • Important to remove bone anterior to the maxillary line to ensure that the entire medial sac is opened
  • The top of lacrimal sac often extends above the attachment of the middle turbinate to the lateral nasal wall
