Long-term outcomes in primary powered endoscopic dacryocystorhinostomy

Area of Science:

• Ophthalmology
• Otorhinolaryngology

Background:

• Epiphora, or excessive tearing, significantly impacts quality of life.
• Dacryocystorhinostomy (DCR) is a surgical procedure to restore tear drainage.
• Powered endoscopic DCR offers a minimally invasive approach to DCR.

Purpose of the Study:

• To evaluate the long-term anatomical and functional success of primary powered endoscopic dacryocystorhinostomy (DCR).

Main Methods:

• Retrospective review of 90 primary powered endoscopic DCR procedures performed between 2003 and 2012.
• Inclusion required a minimum 12-month follow-up post-stent removal.
• Success defined by patent ostium, free dye flow, and epiphora resolution.

Main Results:

• 97.7% anatomical success and 95.5% functional success achieved at long-term follow-up.
• Mean follow-up was 21.8 months.
• Low complication rate, with no intraoperative issues and minimal postoperative complications.

Conclusions:

• Powered endoscopic DCR is a safe procedure with excellent long-term outcomes.
• Adjunctive endonasal procedures should be considered when necessary.
• This technique provides a reliable solution for chronic epiphora.
