Summary

Endoscopic revision dacryocystorhinostomy (DCR) offers a minimally invasive solution for recurrent tear duct obstruction after failed external DCR. This technique effectively addresses intranasal issues, providing relief for most patients.

Area of Science:

  • Ophthalmology
  • Otorhinolaryngology
  • Surgical Innovation

Background:

  • Recurrent lacrimal obstruction can occur after traditional external dacryocystorhinostomy (DCR).
  • Endoscopic nasal surgery enhances intranasal access to the lacrimal drainage system.

Purpose of the Study:

  • To evaluate the efficacy of endoscopic revision DCR for treating recurrent lacrimal obstruction post-external DCR.
  • To assess the feasibility of using endoscopic techniques to address intranasal pathologies contributing to obstruction.

Main Methods:

  • A cohort of 12 patients with recurrent epiphora after external DCR underwent endoscopic revision DCR.
  • Intranasal visualization and correction of pathologies like adhesions, enlarged middle turbinate, and ethmoid sinus disease were performed.
  • No skin incisions were required.

Main Results:

  • Complete relief of lacrimal obstruction was achieved in 9 out of 12 patients (75%).
  • Follow-up ranged from 7 to 25 months.
  • No intraoperative complications were reported.

Conclusions:

  • Endoscopic revision DCR is an effective treatment for recurrent epiphora following failed external DCR.
  • The technique allows for direct visualization and management of intranasal pathology.
  • It should be considered as an alternative to repeat external procedures.
