Endoscopic laser dacryocystorhinostomy (DCR) offers a skinless intranasal approach for blocked tear ducts. This safe and effective holmium:YAG laser procedure successfully treated 85% of patients, avoiding complications.

Area of Science:

  • Ophthalmology
  • Otolaryngology

Background:

  • Nasolacrimal duct obstruction (NLDO) often requires surgical intervention.
  • External dacryocystorhinostomy (DCR) involves a skin incision.
  • Endoscopic techniques offer a minimally invasive alternative.

Purpose of the Study:

  • To evaluate the safety and efficacy of endoscopic laser-assisted dacryocystorhinostomy (DCR) using a holmium:YAG laser.
  • To assess the procedure's success rate in relieving NLDO.
  • To identify and address potential causes of DCR failure.

Main Methods:

  • Forty-six endoscopic laser DCR procedures were performed on 40 patients.
  • The holmium:YAG laser was utilized for its bone-cutting and coagulation properties.
  • Intranasal pathologies contributing to NLDO were identified and managed concurrently.

Main Results:

  • The surgery achieved an 85% success rate in relieving lacrimal obstruction.
  • No intraoperative or postoperative complications were reported.
  • Endoscopic visualization facilitated the correction of contributing factors like ethmoid sinus disease.

Conclusions:

  • Endoscopic laser DCR is a safe and effective treatment for NLDO.
  • The procedure avoids skin incisions, offering a cosmetic advantage.
  • It provides a viable alternative to external DCR, with potential for addressing concurrent sinonasal issues.
