A new adjustable supraglottiscope improves transoral surgery of the supraglottic larynx. This instrument enhances visualization and control, making procedures easier and faster.

Area of Science:

  • Otolaryngology
  • Surgical Instrumentation

Background:

  • Conventional laryngoscopes are ill-suited for supraglottic laryngeal surgery.
  • Limited visualization and instrument access hinder transoral supraglottic procedures.

Purpose of the Study:

  • To introduce and evaluate a novel adjustable supraglottiscope for transoral supraglottic surgery.
  • To assess the impact of the new instrument on surgical visualization, control, and efficiency.

Main Methods:

  • Development and application of a new adjustable supraglottiscope.
  • Clinical use in various transoral supraglottic surgical scenarios.

Main Results:

  • The adjustable supraglottiscope provides wide exposure of the supraglottis and lower pharynx.

  • It allows side instrument introduction, true suspension, and endotracheal tube retraction.
  • Improved visualization, control, hemostasis, and precision were achieved.
  • Transoral supraglottic surgery duration and difficulty were significantly reduced.

    • Conclusions:

    • The adjustable supraglottiscope is a valuable tool for transoral supraglottic surgery.
    • It enhances versatility and efficiency in managing supraglottic larynx and lower pharynx lesions.
