Powered endoscopic dacryocystorhinostomy (DCR) offers a high success rate for nasolacrimal obstruction. This technique with full sac exposure and mucosal anastomosis demonstrates excellent outcomes comparable to traditional methods.

Area of Science:

  • Ophthalmology
  • Otorhinolaryngology

Background:

  • Nasolacrimal duct obstruction causes epiphora and requires effective surgical intervention.
  • Endoscopic dacryocystorhinostomy (DCR) is a minimally invasive surgical approach.

Purpose of the Study:

  • To describe a specific technique of powered endoscopic DCR involving full sac exposure and primary mucosal anastomosis.
  • To report the perioperative and follow-up results of this powered endoscopic DCR procedure.

Main Methods:

  • A prospective, nonrandomized cohort study of 36 patients (47 procedures) undergoing primary or revision powered endoscopic DCR.
  • Data collected included operative and postoperative outcomes, with follow-up assessments via symptom evaluation and endoscopic visualization with fluorescein testing.

Main Results:

Related Experiment Videos

  • The procedure had a high success rate of 95.7% (45 of 47 DCRs patent) after a mean follow-up of 11 months.
  • The only surgical complication was orbital fat exposure in one case.

Conclusions:

  • Powered endoscopic DCR with full sac exposure and primary mucosal apposition is a safe and effective procedure.
  • The success rate is comparable to that of external DCR, offering a viable endoscopic alternative.
