Endoscopic Laser DCR

Indications:

• Epiphora
• Chronic dacryocystitis

Highlights:

• 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
