    Local anesthesia offers safety benefits for laryngoscopy, unlike general anesthesia. A new infiltration method provides deep anesthesia for the tongue base, valleculae, and larynx, enabling suspension laryngoscopy.

    Area of Science:

    • Otolaryngology
    • Anesthesiology

    Background:

    • General anesthesia is trending for laryngoscopy, but local anesthesia offers patient safety and laryngeal function advantages.
    • Topical anesthesia is insufficient for suspension laryngoscopy due to incomplete sensory blockade.

    Purpose of the Study:

    • To describe an infiltration anesthesia method for achieving profound anesthesia of the tongue base, valleculae, and larynx.
    • To enable suspension laryngoscopy using local anesthesia.

    Main Methods:

    • A novel infiltration anesthesia technique was developed and applied.
    • The method targets the base of the tongue, valleculae, and larynx.

    Main Results:

    • Profound anesthesia of the targeted areas was achieved.

  • The described method facilitates suspension laryngoscopy.

    • Conclusions:

    • Local infiltration anesthesia is a viable alternative to general anesthesia for laryngoscopy.
    • This technique enhances patient safety and preserves laryngeal function during endoscopic procedures.
