Area of Science:

  • Ophthalmology
  • Otorhinolaryngology

Background:

  • Nasolacrimal intubation is essential for treating nasolacrimal duct obstruction.
  • Retrieval of intubation probes can be challenging, potentially causing soft tissue injury and bleeding.

Purpose of the Study:

  • To describe a simple method for facilitating steel probe retrieval during nasolacrimal intubation.
  • To reduce complications associated with probe retrieval.

Main Methods:

  • Utilized a low-voltage device (ohmmeter) to confirm contact between the retrieval hook and the steel probe.
  • Applied the technique during monocanalicular and bicanalicular nasolacrimal intubation procedures.

Main Results:

  • The use of an ohmmeter greatly facilitated the retrieval of steel probes.
  • The method proved effective in simplifying a potentially tricky maneuver.

Conclusions:

  • Employing a low-voltage ohmmeter is a practical and effective technique to aid steel probe retrieval in nasolacrimal intubation.
  • This method can potentially minimize operative time and reduce associated soft tissue trauma and bleeding.
