Summary

Endoscopic laser-assisted dacryocystorhinostomy (DCR) offers a high success rate for tear drainage. This minimally invasive technique avoids scarring and reduces patient recovery time compared to traditional methods.

Area of Science:

  • Ophthalmology
  • Otolaryngology
  • Minimally Invasive Surgery

Background:

  • Dacryocystorhinostomy (DCR) aims to restore tear drainage from the lacrimal sac to the nasal cavity.
  • Endonasal techniques improve visualization and reduce complications compared to external approaches.

Purpose of the Study:

  • To evaluate the efficacy and outcomes of endoscopic laser-assisted DCR.
  • To present surgical technique, results, and factors contributing to success.

Main Methods:

  • 31 endoscopic laser-assisted DCR procedures performed on 23 patients over 31 months.
  • Utilized holmium:YAG or argon:HGM lasers.
  • Included adult, pediatric, and revision cases.

Main Results:

  • Achieved a 97% overall success rate with a mean follow-up of 16 months.
  • Successful outcomes in revision cases after failed external DCR.
  • Identified key technical factors for success: large rhinostomy, concurrent intranasal/sinus surgery, laser avoidance in lacrimal sac, and diligent postoperative care.

Conclusions:

  • Endoscopic laser-assisted DCR is a superior alternative to external DCR.
  • The procedure avoids cutaneous scarring, minimizes tissue trauma, and reduces postoperative morbidity.
