Summary

This study introduces a new endoscopic inferior dacryocystorhinostomy (DCR) technique that preserves the lacrimal pump mechanism. The physiological operation demonstrates a high success rate over 90% for nasal lacrimal blockage.

Area of Science:

  • Ophthalmology
  • Otorhinolaryngology

Background:

  • Conventional dacryocystorhinostomy (DCR) often requires extensive bone removal, potentially compromising the lacrimal pump mechanism.
  • Nasal lacrimal blockage necessitates effective surgical interventions.

Purpose of the Study:

  • To describe a physiological endoscopic inferior dacryocystorhinostomy (DCR) operation for nasal lacrimal blockage.
  • To evaluate the safety, efficacy, and long-term success of this minimally invasive DCR technique.

Main Methods:

  • A novel endoscopic inferior DCR procedure marsupializing the inferior lacrimal sac and adjacent duct into the nose.
  • Surgical technique avoids extensive bone removal at the lacrimal fossa.
  • Evaluation of 81 consecutive cases.

Main Results:

  • The endoscopic inferior DCR procedure is safe and quick, not requiring sophisticated instruments.
  • Achieved a success rate exceeding 90% in 81 consecutive patients.
  • Success rates were maintained over time, with most patients exhibiting a wide lacrimal window and preserved superior sac remnant function.

Conclusions:

  • Endoscopic inferior DCR is a safe and effective surgical option for nasal lacrimal blockage.
  • This technique preserves the lacrimal pump mechanism, offering a high success rate.
  • The procedure is minimally invasive and suitable for routine clinical practice.
