A new computer-guided scanner for CO2 laser surgery improves accuracy and reduces operating time by up to 30% compared to manual methods. This technology enhances precision in laryngeal surgeries for various lesions.

Area of Science:

  • Otolaryngology
  • Surgical Technology
  • Laser Surgery

Background:

  • Computer-guided systems are emerging for precise surgical interventions.
  • Carbon dioxide (CO2) laser surgery offers minimally invasive options for laryngeal procedures.
  • Manual guidance in laser surgery can limit accuracy and efficiency.

Purpose of the Study:

  • To clinically evaluate a novel computer-guided scanner for CO2 laser-assisted microincisions.
  • To compare the performance of the scanner-assisted system with a manual micromanipulator (Acuspot).

Main Methods:

  • A prospective study involving 155 patients with laryngeal lesions (benign and early cancers).
  • Comparison of operating times between scanner-assisted and manual laser incisions.
  • Measurement of laser-induced coagulation thickness on 41 surgical specimens.

Main Results:

  • Scanner-assisted incisions were significantly more accurate than manual ones.
  • Operating time was reduced by up to 30% with the scanner-assisted approach.
  • Coagulation thickness was minimal (<10 µm for phonomicrosurgery, <20 µm for other procedures).

Conclusions:

  • The computer-guided scanner provides enhanced accuracy for CO2 laser-assisted microincisions in the larynx.
  • This technology offers a more time-efficient and precise alternative to manual guidance in laryngeal surgery.
