Area of Science:

  • Ophthalmology
  • Otorhinolaryngology
  • Minimally Invasive Surgery

Background:

  • Conventional lacrimal surgery can result in cutaneous scarring, significant surgical trauma, and bleeding.
  • Postoperative recovery and pain are often considerable with traditional approaches.

Purpose of the Study:

  • To evaluate the efficacy and benefits of a novel video-endoscopic, transnasal, laser-assisted lacrimal procedure.
  • To compare this technique with conventional lacrimal surgery in terms of trauma, recovery, and pain.

Main Methods:

  • Twenty video-endoscopic, transnasal, laser-assisted lacrimal procedures were performed on 18 patients (ages 3-88).
  • Both dacryocystorhinostomy and conjunctivodacryocystorhinostomy were accomplished using potassium titanyl phosphate or carbon dioxide lasers.
  • The video endoscope facilitated surgery across diverse intranasal structures.

Main Results:

  • The laser-assisted technique successfully avoided cutaneous scarring and reduced surgical trauma and bleeding.
  • Patients experienced shortened postoperative recovery times and lessened postoperative pain.
  • The procedure was adaptable to various intranasal variations.

Conclusions:

  • Video-endoscopic, transnasal, laser-assisted lacrimal surgery is a safe and effective alternative to conventional methods.
  • This minimally invasive approach offers significant advantages in patient recovery and comfort.
  • The technique serves as an excellent educational tool for training.
