This study compares dacryocystorhinostomy (DCR) techniques, finding similar lacrimal duct permeability. A modified approach using specific forceps and flaps offers improved mucosal recovery and cost-benefit, with minimal complications.

Area of Science:

  • Otolaryngology
  • Ophthalmology
  • Surgical Innovation

Background:

  • Dacryocystorhinostomy (DCR) is increasingly performed by otolaryngologists, utilizing endoscopic endonasal approaches.
  • Traditional DCR techniques and newer endoscopic methods show comparable outcomes in lacrimal duct permeability.

Purpose of the Study:

  • To introduce modifications to the DCR surgical technique.
  • To evaluate if these modifications enhance postoperative mucosal recovery and cost-effectiveness.
  • To compare the outcomes of a modified DCR technique against a conventional method.

Main Methods:

  • A retrospective comparison of two DCR groups: conventional (chisel osteotomy, no flaps; 96 cases) and modified (Smith-Kerrison forceps, with flaps; 40 cases).
  • Evaluation focused on lacrimal duct permeability, postoperative mucosal recovery, and complication rates.

Main Results:

  • Lacrimal duct permeability rates were similar between groups (92.7% vs 87.5%).
  • The modified technique demonstrated a more functional and less aggressive approach, potentially improving mucosal recovery and cost-benefit.
  • No major complications were observed; minor complications like eyelid hematoma occurred infrequently in both groups.

Conclusions:

  • Modified DCR technique using Smith-Kerrison forceps and flaps yields comparable permeability to conventional methods.
  • The modified approach offers advantages in postoperative mucosal recovery and cost-effectiveness.
  • The technique is safe, with a low incidence of minor complications.
