Endoscopic Laser DCR

Running Time: 4:21

 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 an adequate opening into lacrimal sac has been made
• A silastic stent is placed

Keep in Mind:

• Laser is a tool for tissue removal which has both advantages and disadvantages
• Important to remove bone anterior to the maxillary line 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
