Summary

Merocel tamponade offers superior outcomes for mucosal flap fixation during endoscopic dacryocystorhinostomy (DCR) compared to gelfoam. This method resulted in a higher surgical success rate and fewer complications in DCR procedures.

Area of Science:

  • Ophthalmology
  • Surgical Innovation

Background:

  • Nasolacrimal duct obstruction (NLDO) is commonly treated with dacryocystorhinostomy (DCR).
  • Flap-based DCR techniques improve surgical outcomes but are susceptible to post-operative flap dislocation.

Purpose of the Study:

  • To compare the efficacy of gelfoam versus merocel tamponade for securing mucosal flaps in endoscopic DCR.
  • To evaluate which tamponade material leads to better surgical results and fewer complications.

Main Methods:

  • A comparative study involving 52 patients undergoing endoscopic DCR.
  • 26 patients received merocel tamponade for mucosal flap fixation.
  • 26 patients received gelfoam for mucosal flap fixation.

Main Results:

  • Merocel tamponade demonstrated a greater surgical success rate.
  • The merocel tamponade group experienced fewer post-operative complications.
  • Flap fixation was more stable with merocel tamponade.

Conclusions:

  • Merocel tamponade is a successful and effective material for mucosal flap fixation in endoscopic DCR.
  • Utilizing merocel tamponade can lead to improved surgical outcomes and reduced complications in DCR surgery.
