Office-based videoendoscope-assisted laryngeal surgery offers an effective outpatient treatment for various laryngeal lesions. This minimally invasive technique improves vocal function for benign conditions and facilitates biopsy for tumors.

Area of Science:

  • Otolaryngology
  • Minimally Invasive Surgery
  • Laryngeal Pathology

Background:

  • Traditional laryngeal surgeries often require general anesthesia and hospitalization.
  • Limitations exist in visualizing and manipulating delicate laryngeal structures during conventional procedures.

Purpose of the Study:

  • To introduce and evaluate a novel videoendoscope-assisted laryngeal surgery technique performed with office-based equipment.
  • To assess the efficacy and advantages of this minimally invasive approach for treating laryngeal lesions.

Main Methods:

  • A flexible videoendoscope with an integrated charge-coupled device chip was transnasally inserted into anesthetized patients.
  • Specially designed fine-tipped instruments were utilized for lesion removal.
  • The procedure was performed on 114 patients with conditions including polyps, granuloma, and cancer.

Main Results:

  • Postoperative vocal function improved in patients with benign vocal fold lesions, confirmed by aerodynamic and perceptual analyses.
  • Biopsies of laryngeal tumors were successfully obtained.
  • The technique demonstrated applicability to outpatients, enabling functional voice monitoring and delicate bimanual manipulation with high-resolution imaging.

Conclusions:

  • Videoendoscope-assisted laryngeal surgery is a viable, minimally invasive outpatient procedure.
  • The technique offers improved visualization and functional outcomes compared to conventional methods.
  • This approach provides a safe and effective alternative for diagnosing and treating a range of laryngeal pathologies.
