Modifications of the conjunctivodacryocystostomy procedure.

Area of Science:

• Ophthalmology
• Surgical Innovation
• Lacrimal System Surgery

Background:

• Nasolacrimal duct obstruction requires surgical intervention.
• Traditional conjunctivodacryocystostomy involves complex intranasal maneuvers.
• A simplified approach is needed to improve procedural efficiency and patient outcomes.

Purpose of the Study:

• To describe a modified conjunctivodacryocystostomy procedure.
• To evaluate the efficacy and safety of a simplified technique using pre-flanged polyethylene tubing.
• To assess complication rates and management in patients undergoing the modified procedure.

Main Methods:

• A modified conjunctivodacryocystostomy was performed on 36 patients (43 eyes).
• Polyethylene (PE-190) tubing was directly threaded over a Bowman probe into the nasolacrimal duct.
• The procedure avoided traditional intranasal maneuvers.

Main Results:

• The modified technique simplified the conjunctivodacryocystostomy procedure.
• 42 out of 43 inserted tubes remained functional postoperatively.
• Minor complications included tubing shortening (8 eyes) and occasional blockage (3 eyes), which were manageable.

Conclusions:

• The modified conjunctivodacryocystostomy offers a simplified and effective treatment for nasolacrimal duct obstruction.
• The technique demonstrates a high success rate with easily manageable complications.
• This approach represents a valuable alternative for lacrimal drainage surgery.
