Endoscopic Laser DCR


  • 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 that an adequate opening is made into the lacrimal sac
  • A Silastic stent is placed

Keep in Mind/Things to Remember:

  • Laser is a tool for tissue removal which has both advantages as well as disadvantages
  • Important to remove bone anterior to the maxillary line in order to ensure that the entire medial sac is opened
  • Revision cases can actually be easier than primary procedures because bone overlying the lacrimal sac has already been removed
