Endoscopic Primary DCR Part 1 of 2

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:

• 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
