New techniques in suture-aided tear duct intubation

Area of Science:

• Ophthalmology
• Surgical Techniques

Background:

• Nasolacrimal duct intubation is crucial for treating nasolacrimal duct obstruction.
• Current suture pull-through techniques can present challenges with suture accessibility in the nasal cavity.

Purpose of the Study:

• To present modifications to the suture pull-through technique for nasolacrimal duct intubation.
• To describe an alternative method for joining tubing ends without using a knot.

Main Methods:

• Modified suture pull-through technique for improved suture manipulation within the nose.
• Development of a knotless method for securing the intubation tubing.

Main Results:

• Enhanced suture accessibility within the nasal cavity during intubation.
• A functional and reproducible knotless method for tubing end-joining was achieved.

Conclusions:

• The modified technique improves the ease and efficiency of nasolacrimal duct intubation.
• The knotless joining method offers a viable alternative to traditional knotting techniques, potentially reducing complications.
